BACKGROUND OF THE INVENTION

[0003] Herpes viruses are a leading cause of human disease. Herpes viruses cause lifelong, latent infections that can remain silent for long periods of time, and periodically reactivate.

There are 8 human herpesviruses - Herpes Simplex Virus 1 (HSV-1), Herpes Simplex Virus 2 (HSV-2), Varicella-Zoster, Cytomegalovirus, Epstein Barr, Human Herpesvirus 6, Human Herpesvirus 7, and Kaposi's Sarcoma Associated Virus.

[0004] The high prevalence of HSV infection in the U.S., together with the medical and psychological impacts of the disease, makes HSV an important candidate for the development of an effective vaccine. Genital herpes (GH) disease is caused by the herpes simplex viruses (HSVs). HSV-2 is the primary cause of recurrent genital lesions and infects between 10 and 50% of the population worldwide, and in the US, it is estimated that 15% of the population is infected (for review, see (29). HSV-1 infects approximately 60% of the US population and is associated with recurrent orolabial lesions, encephalitis, and keratitis, and is an increasingly common cause of primary GH disease (28). Of great importance worldwide are the findings that genital HSV-2 infection significantly increases the risk of acquisition and transmission of HIV- 1 (for review, see (7, 8, 1 1)). Thus, there is a need in the art for treatments of Herpes viruses, including HSV causing GH. Provided herein are solutions to these and other problems in the art. BRIEF SUMMARY OF THE INVENTION

DETAILED DESCRIPTION OF THE INVENTION

[0009] The abbreviations used herein have their conventional meaning within the chemical and biological arts. [0010] The term "vaccine" is used according to its plain ordinary meaning within medicine and immunology and refers to a composition including an antigenic component for

administration to a subject (e.g. human), which elicits an immune response to the antigenic component. In embodiments a vaccine is a therapeutic. In embodiments, a vaccine is prophylactic. In embodiments a vaccine includes one or more adjuvants. [0011] The term "prime-boost" or "prime boost" as applied to a methodology of administering vaccines is used according to its plain ordinary meaning in virology and immunology and refers to a method of vaccine administration in which a first dose of a vaccine or vaccine component is administered to a subject or patient to begin the administration (prime) and at a later time (e.g. hours, days, weeks, months later) a second vaccine is administered to the same patient or subject (boost). The first and second vaccines may be the same or different but are intended to both elicit an immune response useful in treating or preventing the same disease or condition (e.g. infection by HV, HSV, HHV-1, HHV-2, HHV-3, HHV-4, HHV-5, HHV-6, HHV-7, or HHV-8). In embodiments the prime is a DNA vaccine including one or more viral genes or portions thereof and the boost is a vaccine including one or more viral genes or portions thereof, one or more viral proteins or portions thereof, or one or more inactivated or attenuated viruses. In embodiments, the prime is one or more attenuated or inactivated viruses and the boost is a DNA vaccine including one or more viral genes or portions thereof, one or more viral proteins or portions thereof, or one or more inactivated or attenuated viruses. In embodiments the prime is one or more viral proteins or portions thereof and the boost is a DNA vaccine including one or more viral genes or portions thereof, one or more viral proteins or portions thereof, or one or more inactivated or attenuated viruses. In embodiments, the prime is a vaccine including an inactivated virus (e.g. HV, HSV, HHV-1, HHV-2, HHV-3, HHV-4, HHV-5, HHV-6, HHV-7, or HHV-8) and the boost is a second dose of the same vaccine as the prime.

[0013] An "inactivated Herpes virus" is a herpesvirus which is no longer able to produce evidence of growth or infect a subject. An inactivated Herpes virus thus cannot replicate but remains sufficiently intact to elicit an immune response as described herein. A herpes virus may be inactivated using techniques known in the art including but not limited to heat, radiation (e.g. UV, infrared, alpha, beta, gamma, X-ray, visible, microwave), ultrasonic vibration, or chemical treatment (e.g. formalin). The term "chemical treatment" or "chemical inactivation" as applied to inactivation of a virus (e.g. HV, HSV, HHV-1, HHV-2, HHV-3, HHV-4, HHV-5, HHV-6, HHV-7, or HHV-8), refers to a method of inactivating (as defined herein) a virus including contacting the virus with a chemical agent, wherein the contacting causes the inactivation of the virus.

[0014] The term "formalin" is used according to its plain ordinary meaning in Chemistry and refers to an aqueous solution including formaldehyde (e.g. 37% by mass). The components of formalin are typically designed to be in sufficient quantities to inactivate a virus. In some embodiments, formalin may include methanol.

[0018] The terms "lipopolysaccharide-adjuvant" and "LPS-adjuvant" are used interchangeably herein and refer to a lipopolysaccharide or molecule derived from a lipopolysaccharide commonly employed as part of a vaccine formulation. The LPS-adjuvant may be designed to increase the immune response of a subject when administered to the subject as a component of a vaccine or method of vaccination relative to the absence of the lipopolysaccharide molecule. An LPS-adjuvant may include a portion of an LPS or, in embodiments, an LPS. An LPS-adjuvant may include a modified portion of an LPS (e.g. chemical modification including, for example, additional substituents or bound to a component that is not a portion of an LPS). Thus, in certain instances, an LPS-adjuvant includes a component that is a portion of an LPS and another component that is not a portion of an LPS. An LPS-adjuvant may include a component that corresponds to a portion of an LPS, but which is chemically synthesized. The term

"lipopolysaccharide" and "LPS" are used according to their plain meaning in biology, biochemistry, and immunology and refer to a molecule comprising one or more lipids and one or more polysaccharides covalently bonded together.

[0025] An "antigen" is used in accordance with its plain ordinary meaning within immunology and refers to a molecule that elicits an immunological response or binds to receptor or antibody thereby eliciting an immunological response. The terms "antigenic" or "antigenicity" are used in accordance with their plain ordinary meaning within immunology and refer an immunological response elicited from an antigen. Thus, "antigenic" and "antigenicity" may refer to specific immunological response from a specified subject. In embodiments, the antigenicity is associated with an immunological response from a bird, reptile, or fish. In embodiments, antigenicity is associated with immunological response from a mammal such as, for example, a mouse, rat, guinea pig, rabbit, cow, dog, cat, chimpanzee or human. In embodiments, antigenicity is associated with immunological response from a mouse, rat, guinea pig, or rabbit. In

embodiments, antigenicity is associated with immunological response from a human. The term "antigenic site" therefore refers to a residue of-, a modification of-, a portion of-, or the full- length of- a polynucleotide or polypeptide that elicits an immunological response as described above. In embodiments, an antigenic site is a polypeptide sequence or amino acid residues within a recombinant-Herpes virus protein described herein, including embodiments thereof. [0026] The terms "bind", "bound", "binding", and other verb forms thereof are used in accordance with their plain ordinary meaning within enzymology and biochemistry and refer to the formation of one or more interactions or contacts between two compositions that may optionally interact. Binding may be intermolecular or intramolecular.

[0027] The term "deactivated" when used in reference to a recombinant-Herpes virus protein refers to a protein with decreased activity related to the wild type. The decreased activity may be caused by a modification (e.g. chemical modification or amino acid mutation including, for example, substitution or deletion of an amino acid residue), which decreases the activity of the recombinant-Herpes virus protein compared to a corresponding unmodified recombinant-Herpes virus protein. In embodiments, the activity of the recombinant-Herpes virus protein is decreased by at least 20% 30%, 40%, 50%, 60%, 70%, 80%, 90%, 95%, or 100% activity compared to its corresponding unmodified recombinant-Herpes virus protein.

The modification may be a "deactivating mutation" (e.g. a mutations which deactivates the protein as described above). The modification may be a modification, for example, which increases expression of the recombinant-Herpes virus protein, increases the solubility of the recombinant- Herpes virus protein, alters the translocation or secretion of a recombinant-Herpes virus protein, alters folding of the recombinant-Herpes virus protein, or otherwise alters the activity and/or function of the recombinant-Herpes virus protein. Modification of proteins described herein may be through chemical modification (e.g. chemical conjugation to residues in the protein, and posttranslational modifications known in the art such as thioesterification, glycosylation, formylation, acetylation, methylation, carboxylation, amidation, phosphorylation, lipodation (i.e. addition of a lipid moiety to a polypeptide), oxidation, or reduction.

[0029] As defined herein, the term "inhibition", "inhibit", "inhibiting" and the like in reference to an interaction which negatively affects (e.g. decreases) the activity or function of the protein. In embodiments inhibition refers to reduction of a disease or symptoms of disease. In embodiments inhibition refers to reduction of the growth, proliferation, or spread of a virus (e.g. HV (e.g. an HV selected from the group consisting of HHV-1, HHV-2, HHV-3, HHV-4, HHV-5, HHV-6, HHV-7, and HHV-8)). In embodiments inhibition refers to preventing the infection of a subject by a virus (e.g. HV (e.g. an HV selected from the group consisting of HHV-1, HHV-2, HHV-3, HHV-4, HHV-5, HHV-6, HHV-7, and HHV-8)). In embodiments, inhibition refers to a reduction in the activity of a signal transduction pathway or signaling pathway. Thus, inhibition includes, at least in part, partially or totally blocking stimulation, decreasing, preventing, or delaying activation, or inactivating, desensitizing, or down-regulating the signaling pathway or enzymatic activity or the amount of a protein. [0030] The term "modulate" is used in accordance with its plain ordinary meaning and refers to the act of changing or varying one or more properties. "Modulation" refers to the process of changing or varying one or more properties. For example, as applied to the effects of a modulator on a target, to modulate means to change by increasing or decreasing a property or function of the target or the amount of the target.

[0031] A nucleic acid (such as a polynucleotide), amino acid (such as a polypeptide), or a cell is "recombinant" when it is artificial or engineered, or derived from or contains an artificial or engineered protein or nucleic acid (e.g. non-natural or not wild type). For example, a polynucleotide that is inserted into a vector or any other heterologous location, e.g., in a genome of a recombinant organism, such that it is not associated with nucleotide sequences that normally flank the polynucleotide as it is found in nature is a recombinant polynucleotide. A protein expressed in vitro or in vivo from a recombinant polynucleotide is an example of a recombinant polypeptide. Likewise, a polynucleotide sequence or polypeptide sequence that does not appear in nature, for example a variant of a naturally occurring gene, is recombinant.

[0032] An "endogenous-Herpes virus protein" refers to a protein that is encoded by a Herpes virus and is within or associated with the virus particle. An endogenous-Herpes virus protein may refer to a protein encoded by a Herpes virus, is within or associated with the virus particle, and has function in, for example, forming the envelope, capsid, or matrix (i.e. tegument) of a virus particle, or, for example, in regulating the expression of early or late viral genes (e.g.

immediate early proteins, early proteins, early-late proteins, or late proteins). A "corresponding endogenous -Herpes virus protein" refers to an endogenous-Herpes virus protein having sequence identity (e.g. at least 70%, 75%, 80%, 85%, 90%, 95%, 96%, 97%, 98%, 99% or 100%) to a recombinant-Herpes virus protein. In embodiments, the sequence identity refers to the full- length of the polypeptide. In embodiments, the sequence identity refers to a contiguous length of the polypeptide (e.g. about 100, 200, 300, 400, 500, 600, 650, 700, 750, 800, 850, 900, 950, 1000, 1100, 1200, 1300, 1400, 1500, or 1600 amino acids).

[0043] "Nucleic acid" or "oligonucleotide" or "polynucleotide" or grammatical equivalents used herein means at least two nucleotides covalently linked together. The term "nucleic acid" includes single-, double-, or multiple-stranded DNA, RNA and analogs (derivatives) thereof. Oligonucleotides are typically from about 5, 6, 7, 8, 9, 10, 12, 15, 25, 30, 40, 50 or more nucleotides in length, up to about 100 nucleotides in length. Nucleic acids and polynucleotides are a polymers of any length, including longer lengths, e.g., 200, 300, 500, 1000, 2000, 3000, 5000, 7000, 10,000, etc. In embodiments, the nucleic acids herein contain phosphodiester bonds. In embodiments, nucleic acid analogs are included that may have alternate backbones, comprising, e.g., phosphoramidate, phosphorothioate, phosphorodithioate, or O- methylphosphoroamidite linkages (see Eckstein, Oligonucleotides and Analogues: A Practical Approach, Oxford University Press); and peptide nucleic acid backbones and linkages. Other analog nucleic acids include those with positive backbones; non-ionic backbones, and non-ribose backbones, including those described in U.S. Patent Nos. 5,235,033 and 5,034,506, and Chapters 6 and 7, ASC Symposium Series 580, Carbohydrate Modifications in Antisense Research, Sanghui & Cook, eds. Nucleic acids containing one or more carbocyclic sugars are also included within one definition of nucleic acids. Modifications of the ribose-phosphate backbone may be done for a variety of reasons, e.g., to increase the stability and half-life of such molecules in physiological environments or as probes on a biochip. Mixtures of naturally occurring nucleic acids and analogs can be made; alternatively, mixtures of different nucleic acid analogs, and mixtures of naturally occurring nucleic acids and analogs may be made. [0044] A particular nucleic acid sequence also encompasses "splice variants." Similarly, a particular protein encoded by a nucleic acid encompasses any protein encoded by a splice variant of that nucleic acid. "Splice variants," as the name suggests, are products of alternative splicing of a gene. After transcription, an initial nucleic acid transcript may be spliced such that different (alternate) nucleic acid splice products encode different polypeptides. Mechanisms for the production of splice variants vary, but include alternate splicing of exons. Alternate

polypeptides derived from the same nucleic acid by read-through transcription are also encompassed by this definition. Any products of a splicing reaction, including recombinant forms of the splice products, are included in this definition.

[0045] Nucleic acid is "operably linked" when it is placed into a functional relationship with another nucleic acid sequence. For example, DNA for a pre-sequence or secretory leader is operably linked to DNA for a polypeptide if it is expressed as a preprotein that participates in the secretion of the polypeptide; a promoter or enhancer is operably linked to a coding sequence if it affects the transcription of the sequence; or a ribosome binding site is operably linked to a coding sequence if it is positioned so as to facilitate translation. Generally, "operably linked" means that the DNA sequences being linked are near each other, and, in the case of a secretory leader, contiguous and in reading phase. However, enhancers do not have to be contiguous. Linking is accomplished by ligation at convenient restriction sites. If such sites do not exist, then synthetic oligonucleotide adaptors or linkers are used in accordance with conventional practice.

[0046] The term "expression" includes any step involved in the production of the polypeptide including, but not limited to, transcription, post-transcriptional modification, translation, post- translational modification, and secretion. [0047] The terms "polypeptide," "peptide" and "protein" are used interchangeably herein to refer to a polymer of amino acid residues, wherein the polymer may optionally be conjugated to a moiety that does not consist of amino acids. The terms apply to amino acid polymers in which one or more amino acid residue is an artificial chemical mimetic of a corresponding naturally occurring amino acid, as well as to naturally occurring amino acid polymers and non-naturally occurring amino acid polymer.

[0048] The term "peptidyl" and "peptidyl moiety" means a monovalent peptide.

[0049] The term "amino acid" refers to naturally occurring and synthetic amino acids, as well as amino acid analogs. Naturally occurring amino acids are those encoded by the genetic code, as well as those amino acids that are later modified, e.g., hydroxyproline, γ-carboxyglutamate, and O-phosphoserine. Amino acid analogs refers to compounds that have the same basic chemical structure as a naturally occurring amino acid, i.e., an a-carbon that is bound to a hydrogen, a carboxyl group, an amino group, and an R group, e.g., homoserine, norleucine, methionine sulfoxide, methionine methyl sulfonium. Such analogs have modified R groups (e.g., norleucine) or modified peptide backbones, but retain the same basic chemical structure as a naturally occurring amino acid. Amino acid mimetics refers to chemical compounds that have a structure that is different from the general chemical structure of an amino acid, but that functions in a manner similar to a naturally occurring amino acid. An oligomer comprising amino acid mimetics is a peptidomimetic. A peptidomimetic moiety is a monovalent peptidomimetic.

[0050] Amino acids may be referred to herein by either their commonly known three letter symbols or by the one-letter symbols recommended by the IUPAC-IUB Biochemical

Nomenclature Commission. Nucleotides, likewise, may be referred to by their commonly accepted single-letter codes. [0051] An amino acid or nucleotide base "position" is denoted by a number that sequentially identifies each amino acid (or nucleotide base) in the reference sequence based on its position relative to an N-terminus (or 5'-end). Due to deletions, insertions, truncations, fusions, and the like that must be taken into account when determining an optimal alignment, in general the amino acid residue number in a test sequence determined by simply counting from the N- terminus will not necessarily be the same as the number of its corresponding position in the reference sequence. For example, in a case where a variant has a deletion relative to an aligned reference sequence, there will be no amino acid in the variant that corresponds to a position in the reference sequence at the site of deletion. Where there is an insertion in an aligned reference sequence, that insertion will not correspond to a numbered amino acid position in the reference sequence. In the case of truncations or fusions there can be stretches of amino acids in either the reference or aligned sequence that do not correspond to any amino acid in the corresponding sequence.

[0052] The terms "numbered with reference to" or "corresponding to," when used in the context of the numbering of a given amino acid or polynucleotide sequence, refers to the numbering of the residues of a specified reference sequence when the given amino acid or polynucleotide sequence is compared to the reference sequence. [0053] A "conservative substitution" as used with respect to amino acids, refers to the substitution of an amino acid with a chemically similar amino acid. Amino acid substitutions which often preserve the structural and/or functional properties of the polypeptide in which the substitution is made are known in the art and are described, for example, by H. Neurath and R.L. Hill, 1979, in "The Proteins," Academic Press, New York. The most commonly occurring exchanges are isoleucine/valine, tyrosine/phenylalanine, aspartic acid/glutamic acid, lysine/arginine, methionine/leucine, aspartic acid/asparagine, glutamic acid/glutamine, leucine/isoleucine, methionine/isoleucine, threonine/serine, tryptophan/phenylalanine, tyrosine/histidine, tyrosine/tryptophan, glutamine/arginine, histidine/asparagine,

histidine/glutamine, lysine/asparagine, lysine/glutamine, lysine/glutamic acid,

phenylalanine/leucine, phenylalanine/methionine, serine/alanine, serine/asparagine,

valine/leucine, and valine/methionine. The following eight groups each contain amino acids that are conservative substitutions for one another: 1) Alanine (A), Glycine (G); 2) Aspartic acid (D), Glutamic acid (E); 3) Asparagine (N), Glutamine (Q); 4) Arginine (R), Lysine (K); 5) Isoleucine (I), Leucine (L), Methionine (M), Valine (V); 6) Phenylalanine (F), Tyrosine (Y), Tryptophan (W); 7) Serine (S), Threonine (T); and 8) Cysteine (C), Methionine (M) (see, e.g., Creighton,

Proteins (1984)). In some embodiments, there may be at least 1, at least 2, at least 3, at least 4, at least 5, at least 6, at least 7, at least 8, at least 9, at least 10, at least 15, at least 20, at least 25, at least 30, at least 35, or at least 40 conservative substitutions. In some embodiments, there may be 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 15, 20, 25, 30, 35, or 40 conservative substitutions. [0054] The term "amino acid substitution set" or "substitution set" refers to a group of amino acid substitutions. A substitution set can have 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 1 1, 12, 13, 14, 15, or more amino acid substitutions. A "point mutation" refers to mutation of a single residue in a polynucleotide or polypeptide sequence. [0055] The term "isolated" refers to a nucleic acid, polynucleotide, polypeptide, protein, or other component that is partially or completely separated from components with which it is normally associated (other proteins, nucleic acids, cells, etc.). In embodiments, an isolated polypeptide or protein is a recombinant polypeptide or protein. [0056] An amino acid or peptide is "heterologous" to another sequence with which it is operably linked if the two sequences are not associated in nature.

[0057] "Identity" or "percent identity," in the context of two or more polynucleotide sequences or polypeptide sequences, refers to two or more sequences or subsequences that are the same or have a specified percentage of amino acid residues that are the same (e.g., share at least about 70%, at least about 75%, at least about 80%, at least about 85%, at least about 88% identity, at least about 89%, at least about 90%, at least about 91%, at least about 92%, at least about 93%, at least about 94%, at least about 95%, at least about 96%, at least about 97%, at least about 98%, or at least about 99% identity) over a specified region to a reference sequence, when compared and aligned for maximum correspondence over a comparison window, or designated region as measured using a sequence comparison algorithms or by manual alignment and visual inspection.

[0058] Optimal alignment of sequences for comparison and determination of sequence identity can be determined by a sequence comparison algorithm or by visual inspection (see, generally, Ausubel et al, infra). When optimally aligning sequences and determining sequence identity by visual inspection, percent sequence identity is calculated as the number of residues of the test sequence that are identical to the reference sequence divided by the number of non-gap positions and multiplied by 100. When using a sequence comparison algorithm, test and reference sequences are entered into a computer, subsequence coordinates and sequence algorithm program parameters are designated. The sequence comparison algorithm then calculates the percent sequence identities for the test sequences relative to the reference sequence, based on the program parameters as known in the art, for example BLAST or BLAST 2.0. For example, comparison can be conducted, e.g., by the local homology algorithm of Smith & Waterman, 1981, Adv. Appl. Math. 2:482, by the homology alignment algorithm of Needleman & Wunsch, 1970, J. Mol. Biol. 48:443, by the search for similarity method of Pearson & Lipman, 1988, Proc. Nat'l. Acad. Sci. USA 85:2444, or by computerized implementations of these algorithms (GAP, BESTFIT, FASTA, and TFASTA in the Wisconsin Genetics Software Package, Genetics Computer Group, 575 Science Dr., Madison, Wis.). Thus alignment can be carried out for sequences that have deletions and/or additions, as well as those that have substitutions, as well as naturally occurring, e.g., polymorphic or allelic variants, and man-made variants.

[0059] The phrase "substantial sequence identity" or "substantial identity," in the context of two polypeptide sequences, refers to a sequence that has at least 70% identity to a reference sequence. Percent identity can be any integer from 70% to 100%. Two polypeptide sequences that have 100% sequence identity are said to be "identical." A polypeptide sequence is said to have "substantial sequence identity" to a reference sequence when the sequences have at least about 70%, at least about 75%, at least 80%, at least 85%, at least 90%, at least 91%, at least 92%, at least 93%, at least 94%, at least 95%, at least 96%, at least 97%, at least 98%, or at least 99% or greater sequence identity as determined using the methods described herein, such as BLAST using standard parameters as described above.

[0060] The term "sulfated polysaccharide" is used according to its plain ordinary meaning in biochemistry and glycobiology and refers to two or more covalently bonded monosaccharides (including nitrogen containing monosaccharides), wherein one or more of the monosaccharides is sulfated. In embodiments, a sulfated polysaccharide may be a synthetically made or modified sulfated polysaccharide or a synthetically sulfated polysaccharide. Examples include, but are not limited to, heparin, heparan sulfate, and dextran sulfate.

[0061] The term "sulfonated polysaccharide" is used according to its plain ordinary meaning in biochemistry and glycobiology and refers to two or more covalently bonded monosaccharides (including nitrogen containing monosaccharides), wherein one or more of the monosaccharides is sulfonated. In embodiments, a sulfonated polysaccharide may be a synthetically made or modified sulfonated polysaccharide or a synthetically sulfonated polysaccharide.

Non-limiting examples include humans, other mammals, bovines, rats, mice, dogs, monkeys, goat, sheep, cows, deer, and other non-mammalian animals. In some embodiments, a patient is human. In some embodiments, a patient or subject in need thereof or a patient in need thereof, refers to a living organism (e.g. human) at risk of developing, contracting, or having a disease or condition (e.g. HV (e.g. an HV such as, for example, HHV-1, HHV-2, HHV-3, HHV-4, HHV-5, HHV-6, HHV-7, and HHV-8) or infection or disease associated with an HV (e.g. an HV such as, for example, HHV-1, HHV-2, HHV-3, HHV-4, HHV-5, HHV-6, HHV-7, and HHV-8)).

[0065] An "effective amount" is an amount sufficient for a compound to accomplish a stated purpose relative to the absence of the compound (e.g. achieve the effect for which it is administered, treat a disease, reduce spread of HV (e.g. an HV such as, for example, HHV-1,

HHV-2, HHV-3, HHV-4, HHV-5, HHV-6, HHV-7, and HHV-8), reduce one or more symptoms of a disease or condition (e.g. lesions, virus production, lytic cycle)). An example of an

"effective amount" is an amount sufficient to contribute to the treatment, prevention, or reduction of a symptom or symptoms of a disease, also be referred to herein as a "therapeutically effective amount." A "reduction" of a symptom or symptoms (and grammatical equivalents of this phrase) means decreasing of the severity or frequency of the symptom(s), or elimination of the symptom(s). A "prophylactically effective amount" of a composition (vaccine) is an amount of a composition that, when administered to a subject, will have the intended prophylactic effect, e.g., preventing or delaying the onset (or reoccurrence) of an injury, disease (e.g. HV (e.g. an HV such as, for example, HHV-1, HHV-2, HHV-3, HHV-4, HHV-5, HHV-6, HHV-7, and HHV-8) infection), pathology or condition, or reducing the likelihood of the onset (or reoccurrence) of an injury, disease, pathology, or condition, or their symptoms. The full prophylactic effect does not necessarily occur by administration of one dose, and may occur only after administration of a series of doses (e.g. prime-boost). Thus, a prophylactically effective amount may be

administered in one or more administrations. The exact amounts will depend on the purpose of the treatment, and will be ascertainable by one skilled in the art using known techniques (see, e.g., Lieberman, Pharmaceutical Dosage Forms (vols. 1-3, 1992); Lloyd, The Art, Science and Technology of Pharmaceutical Compounding (1999); Pickar, Dosage Calculations (1999); and Remington: The Science and Practice of Pharmacy, 20th Edition, 2003, Gennaro, Ed.,

Lippincott, Williams & Wilkins).

[0066] As used herein, the term "administering" means oral administration, administration as a suppository, topical contact, intravenous, intraperitoneal, intramuscular, intralesional, intrathecal, intranasal, intradermal, mucosal, intrarectal, intravaginal, topical, transcutaneous (e.g. as in

Combadie ^' re ,PLoS ONE 5(5): el0818), or subcutaneous administration, or the implantation of a slow-release device, e.g., a mini-osmotic pump, to a subject. In embodiments, the administration is intramuscular or subcutaneous administration. Administration may be by any route, including parenteral and transmucosal (e.g., buccal, sublingual, palatal, gingival, nasal, vaginal, rectal, or transdermal). Parenteral administration includes, e.g., intravenous, intramuscular, intra-arteriole, intradermal, subcutaneous, intraperitoneal, intraventricular, and intracranial. Other modes of delivery include, but are not limited to, the use of liposomal formulations, intravenous infusion, transdermal patches, etc.

[0067] By "co-administer" it is meant that a composition described herein is administered at the same time, just prior to, or just after the administration of one or more additional therapies, for example HV (e.g. HHV-1, HHV-2, HHV-3, HHV-4, HHV-5, HHV-6, HHV-7, or HHV-8) infection therapies such as antiviral drugs (e.g. acyclovir, famciclovir, valacyclovir) or a different HV (e.g. HHV-1, HHV-2, HHV-3, HHV-4, HHV-5, HHV-6, HHV-7, or HHV-8) vaccine (e.g. DNA vaccine, DNA vaccine including different genes, isolated protein vaccine, different inactivated virus vaccine). The vaccine compositions herein can be administered alone or can be coadministered to the patient. Coadministration is meant to include simultaneous or sequential administration of the compounds individually or in combination (more than one composition) and includes vaccine administration in a prime-boost method. Thus, the preparations can also be combined, when desired, with other active substances (e.g. to reduce metabolic degradation, increase immune response (e.g. adjuvant)). The compositions described herein can be delivered transdermally, by a topical route, transcutaneously, formulated as applicator sticks, solutions, suspensions, emulsions, gels, creams, ointments, pastes, jellies, paints, powders, and aerosols. The vaccine compositions herein can be delivered intramuscularly or subcutaneously via administration of an HV vaccine. An "administration device" as used herein refers to a device used to administer the vaccine compositions described herein. Administration devices include, but are not limited, to devices for oral, topical, inhalation, or injection of the vaccine

compositions described herein. Exemplary administration devices include, but are not limited to, ampoules, droppers, patches, sprays, pumps, IV lines, syringes.

[0068] The term "administer (or administering) an HV vaccine" means administering a composition that prevents or treats an HV (e.g. HHV-1, HHV-2, HHV-3, HHV-4, HHV-5, HHV-6, HHV-7, or HHV-8) infection in a subject. Administration may include, without being limited by mechanism, allowing sufficient time for the HV (e.g. HHV-1, HHV-2, HHV-3, HHV- 4, HHV-5, HHV-6, HHV-7, or HHV-8) vaccine to induce an immune response in the subject or to reduce one or more symptoms of a disease (e.g. HHV-1, HHV-2, HHV-3, HHV-4, HHV-5, HHV-6, HHV-7, or HHV-8 infection).

[0069] The terms "dose" and "dosage" are used interchangeably herein. A dose refers to the amount of active ingredient given to an individual at each administration. For the present methods and compositions provided herein, the dose may generally refer to the amount of disease (e.g. HV (e.g. HHV-1, HHV-2, HHV-3, HHV-4, HHV-5, HHV-6, HHV-7, or HHV-8) infection) treatment. The dose will vary depending on a number of factors, including the range of normal doses for a given therapy, frequency of administration; size and tolerance of the individual; severity of the condition; risk of side effects; and the route of administration. One of skill will recognize that the dose can be modified depending on the above factors or based on therapeutic progress. The term "dosage form" refers to the particular format of the

pharmaceutical or pharmaceutical composition, and depends on the route of administration. For example, a dosage form can be in a liquid form for nebulization, e.g., for inhalants, in a tablet or liquid, e.g., for oral delivery, or a saline solution, e.g., for injection. [0070] "Pharmaceutically acceptable excipient" and "pharmaceutically acceptable carrier" refer to a substance that aids the administration of an active agent to and absorption by a subject and can be included in the compositions of the present invention without causing a significant adverse toxicological effect on the patient. Non-limiting examples of pharmaceutically acceptable excipients include water, NaCl, normal saline solutions, lactated Ringer's, normal sucrose, normal glucose, binders, fillers, disintegrants, lubricants, coatings, sweeteners, flavors, salt solutions (such as Ringer's solution), alcohols, oils, gelatins, carbohydrates such as lactose, amylose or starch, fatty acid esters, hydroxymethycellulose, polyvinyl pyrrolidine, and colors, and the like. Such preparations can be sterilized and, if desired, mixed with auxiliary agents such as lubricants, preservatives, stabilizers, wetting agents, emulsifiers, salts for influencing osmotic pressure, buffers, coloring, and/or aromatic substances and the like that do not deleteriously react with the compounds of the invention. One of skill in the art will recognize that other pharmaceutical excipients are useful in the present invention. [0071] The term "preparation" is intended to include the formulation of the active compound with encapsulating material as a carrier providing a capsule in which the active component with or without other carriers, is surrounded by a carrier, which is thus in association with it.

Similarly, cachets and lozenges are included. Tablets, powders, capsules, pills, cachets, and lozenges can be used as solid dosage forms suitable for oral administration. [0072] The term "vaccinate", or additional verb forms thereof, refers to administering a vaccine to a subject (e.g. human) and eliciting an antigen specific immune response, wherein the antigen is included in the vaccine. The term "vaccinate" may also refer to eliciting an antigen specific immune response against an administered antigen. In some embodiments, vaccinate is to provide prophylaxis against a disease or infectious agent (e.g. HV, HSV, HHV-1, HHV-2, HHV-3, HHV-4, HHV-5, HHV-6, HHV-7, or HHV-8).

[0073] The term "virus particle" is used according to its plain ordinary meaning within virology and refers to a virion including the viral genome (e.g. DNA, RNA, single strand, double strand), viral capsid and associated proteins, and in the case of enveloped viruses (e.g. HV, HSV, HHV-1, HHV-2, HHV-3, HHV-4, HHV-5, HHV-6, HHV-7, or HHV-8), an envelope including lipids and optionally components of host cell membranes, and/or viral proteins.

[0074] The term "plaque forming units" is used according to its plain ordinary meaning in virology and refers to a unit of measurement based on the number of plaques per unit volume of a sample. In embodiments the units are based on the number of plaques that could form when infecting a monolayer of susceptible cells. Plaque forming unit equivalents are units of measure of inactivated virus. In embodiments, plaque forming unit equivalents are derived from plaque forming units for a sample prior to inactivation. [0075] The term "viral shedding" is used according to its plain ordinary meaning in medicine and virology and refers to the production and release of virus from an infected cell. In embodiments, the virus is released from a cell of a subject. In embodiments virus is released into the environment from an infected subject. [0076] The term "lesion" is used according to its plain ordinary meaning within medicine and refers to an abnormality or damage to the tissue of a subject.

[0077] "Contacting" is used in accordance with its plain ordinary meaning and refers to the process of allowing at least two distinct species (e.g. compositions, vaccines, virus,

biomolecules, or cells) to become sufficiently proximal to react, interact or physically touch. It should be appreciated; however, the resulting reaction product can be produced directly from a reaction between the added reagents or from an intermediate from one or more of the added reagents which can be produced in the reaction mixture. In embodiments, contacting refers to allowing radiation (e.g. UV, gamma) to interact with matter (e.g. virus, virus component, virus protein, virus nucleic acid). In embodiments, contacting refers to allowing the vaccine compositions described herein to interact with a host immune system to elicit an immunological response.

[0078] The term "contacting" may include allowing two species to react, interact, or physically touch, wherein the two species may be a composition (e.g. vaccine) as described herein and a cell, virus, virus particle, protein, enzyme, or patient. In embodiments contacting includes allowing a composition described herein to interact with a protein or enzyme that is involved in a signaling pathway. In embodiments contacting includes allowing a composition described herein to interact with an HV (e.g. an HV selected from the group consisting of HHV-1, HHV-2, HHV- 3, HHV-4, HHV-5, HHV-6, HHV-7, and HHV-8). In embodiments contacting includes allowing an agent described herein to interact with an HV (e.g. an HV selected from the group consisting of HHV-1, HHV-2, HHV-3, HHV-4, HHV-5, HHV-6, HHV-7, and HHV-8) and inactivate the HV (e.g. an HV selected from the group consisting of HHV-1, HHV-2, HHV-3, HHV-4, HHV-5, HHV-6, HHV-7, and HHV-8).

[0079] The term "associated" or "associated with" as used herein to describe a disease (e.g. a virus associated disease, HV associated disease, HSV associated disease, HHV-1 associated disease, HHV-2 associated disease, HHV-3 associated disease, HHV-4 associated disease, HHV- 5 associated disease, HHV-6 associated disease, HHV-7 associated disease, or HHV-8 associated disease) refers to a disease caused by, characterized by, or a symptom of the disease is caused or characterized by, what is described as disease associated or what is described as associated with the disease. For example, a disease associated with HSV2 or HSV2 infection may be a disease that results (entirely or partially) from HSV2 or HSV2 infection. As used herein, what is described as being associated with a disease, if a causative agent, could be a target for treatment of the disease. For example, a disease associated with HSV2 or HSV2 infection, may be treated with an HSV2 vaccine as described herein (including embodiments). For example, a disease associated with HSV2 may be a disease that a subject with HSV2 or HSV2 infection is at higher risk of developing as compared to a subject without HSV2 or HSV2 infection.

[0080] "Control" or "control experiment" is used in accordance with its plain ordinary meaning and refers to an experiment in which the subjects or reagents of the experiment are treated as in a parallel experiment except for omission of a procedure, reagent, or variable of the experiment. In some instances, the control is used as a standard of comparison in evaluating experimental effects. In embodiments, a control is the measurement of HV (e.g. an HV selected from the group consisting of HHV-1, HHV-2, HHV-3, HHV-4, HHV-5, HHV-6, HHV-7, and HHV-8) infection or one or more symptoms of HV (e.g. an HV selected from the group consisting of HHV-1, HHV-2, HHV-3, HHV-4, HHV-5, HHV-6, HHV-7, and HHV-8) infection in the absence of a composition (e.g. vaccine) as described herein (including embodiments).

II. Pharmaceutical compositions

[0126] In embodiments, the vaccine composition is formulated as a pharmaceutical composition. The pharmaceutical composition includes an inactivated Herpes virus as described herein including embodiments thereof, a recombinant-Herpes virus-protein as described herein including embodiments thereof, a vaccine adjuvant as described herein including embodiments thereof, and a pharmaceutically acceptable excipient.

[0127] The pharmaceutical composition may include an inactivated Herpes virus as described herein, including embodiments thereof, a recombinant-Herpes virus-protein as described herein including embodiments thereof, a LPS-adjuvant or an aluminum-based mineral salt adjuvant, and a pharmaceutically acceptable excipient. The pharmaceutical composition may include an inactivated Herpes virus as described herein, including embodiments thereof, a recombinant- Herpes virus-protein as described herein including embodiments thereof, a LPS-adjuvant and an aluminum-based mineral salt adjuvant, and a pharmaceutically acceptable excipient. The pharmaceutical composition may include an inactivated Herpes virus as described herein, including embodiments thereof, a recombinant-Herpes virus-protein as described herein including embodiments thereof, a MPL and an aluminum-based mineral salt adjuvant (e.g.

aluminum hydroxide or aluminum phosphate) , and a pharmaceutically acceptable excipient.

[0128] The pharmaceutical compositions described herein, including embodiments thereof can be administered alone or can be coadministered to the patient. Coadministration is meant to include simultaneous or sequential administration of the compositions individually or in combination (more than one composition). Thus, the preparations can also be combined, when desired, with other active substances (e.g. to reduce metabolic degradation, increase immune response (e.g. adjuvants)). An example of co-administration of the vaccine compositions described herein is a prime-boost method of administration.

[0129] The pharmaceutical compositions described herein can be prepared and administered in a wide variety of oral, parenteral and topical dosage forms. Oral preparations include tablets, pills, powder, dragees, capsules, liquids, lozenges, cachets, gels, syrups, slurries, suspensions, etc., suitable for ingestion by the patient. The pharmaceutical compositions described herein thereof can also be administered by injection, that is, intravenously, intramuscularly, intracutaneously, subcutaneous ly, intraduodenally, or intraperitoneally. Also, the pharmaceutical compositions described herein can be administered by inhalation, for example, intranasally. Additionally, the pharmaceutical compositions described herein can be administered

transdermally. It is also envisioned that multiple routes of administration (e.g., intramuscular, oral, transdermal, mucosal, intranasal, intrarectal, intravaginal, subcutaneous, transcutaneous, topical, intradermal) can be used to administer the compositions of the invention.

[0130] For preparing the pharmaceutical compositions described herein from the vaccine compositions described herein, including embodiments thereof, pharmaceutically acceptable carriers may be added which can be either solid or liquid. Solid form preparations include powders, tablets, pills, capsules, cachets, suppositories, and dispersible granules. A solid carrier can be one or more substances, which may also act as diluents, flavoring agents, binders, preservatives, tablet disintegrating agents, or an encapsulating material. [0131] In powders, the carrier is a finely divided solid in a mixture with the finely divided active component (e.g. a vaccine composition). In tablets, the active component is mixed with the carrier having the necessary binding properties in suitable proportions and compacted in the shape and size desired. The powders and tablets preferably contain from 5% to 70% of the active compound.

[0132] Suitable solid excipients include, but are not limited to, magnesium carbonate;

magnesium stearate; talc; pectin; dextrin; starch; tragacanth; a low melting wax; cocoa butter; carbohydrates; sugars including, but not limited to, lactose, sucrose, mannitol, or sorbitol, starch from corn, wheat, rice, potato, or other plants; cellulose such as methyl cellulose,

hydroxypropylmethyl-cellulose, or sodium carboxymethylcellulose; and gums including arabic and tragacanth; as well as proteins including, but not limited to, gelatin and collagen. If desired, disintegrating or solubilizing agents may be added, such as the cross-linked polyvinyl pyrrolidone, agar, alginic acid, or a salt thereof, such as sodium alginate.

[0133] Dragee cores are provided with suitable coatings such as concentrated sugar solutions, which may also contain gum arabic, talc, polyvinylpyrrolidone, carbopol gel, polyethylene glycol, and/or titanium dioxide, lacquer solutions, and suitable organic solvents or solvent mixtures. Dyestuffs or pigments may be added to the tablets or dragee coatings for product identification or to characterize the quantity of active composition (i.e., dosage). Pharmaceutical preparations of the vaccine compositions described herein can also be used orally using, for example, push-fit capsules made of gelatin, as well as soft, sealed capsules made of gelatin and a coating such as glycerol or sorbitol.

[0134] For preparing suppositories, a low melting wax, such as a mixture of fatty acid glycerides or cocoa butter, is first melted and the active composition is dispersed homogeneously therein, as by stirring. The molten homogeneous mixture is then poured into convenient sized molds, allowed to cool, and thereby to solidify.

[0135] Liquid form preparations include solutions, suspensions, and emulsions, for example, water or water/propylene glycol solutions. For parenteral injection, liquid preparations can be formulated in solution in aqueous polyethylene glycol solution.

[0136] When parenteral application is needed or desired, particularly suitable admixtures for the compounds of the invention are injectable, sterile solutions, preferably oily or aqueous solutions, as well as suspensions, emulsions, or implants, including suppositories. In particular, carriers for parenteral administration include aqueous solutions of dextrose, saline, pure water, ethanol, glycerol, propylene glycol, peanut oil, sesame oil, polyoxyethylene-block polymers, and the like. Ampules are convenient unit dosages. The vaccine compositions described herein, including embodiments thereof can also be incorporated into liposomes or administered via transdermal pumps or patches. Pharmaceutical admixtures suitable for use herein are well- known to those of skill in the art and are described, for example, in Pharmaceutical Sciences (17th Ed., Mack Pub. Co., Easton, PA) and WO 96/05309, the teachings of both of which are hereby incorporated by reference. [0137] Aqueous solutions suitable for oral use can be prepared by dissolving the active component (e.g. vaccine compositions described herein, including embodiments, examples) in water and adding suitable colorants, flavors, stabilizers, and thickening agents as desired.

Aqueous suspensions suitable for oral use can be made by dispersing the finely divided active component in water with viscous material, such as natural or synthetic gums, resins, methylcellulose, sodium carboxymethylcellulose, hydroxypropylmethylcellulose, sodium alginate, polyvinylpyrrolidone, gum tragacanth and gum acacia, and dispersing or wetting agents such as a naturally occurring phosphatide (e.g., lecithin), a condensation product of an alkylene oxide with a fatty acid (e.g., polyoxyethylene stearate), a condensation product of ethylene oxide with a long chain aliphatic alcohol (e.g., heptadecaethylene oxycetanol), a condensation product of ethylene oxide with a partial ester derived from a fatty acid and a hexitol (e.g.,

polyoxyethylene sorbitol mono-oleate), or a condensation product of ethylene oxide with a partial ester derived from fatty acid and a hexitol anhydride (e.g., polyoxyethylene sorbitan mono-oleate). The aqueous suspension can also contain one or more preservatives such as ethyl or n-propyl p-hydroxybenzoate, one or more coloring agents, one or more flavoring agents and one or more sweetening agents, such as sucrose, aspartame or saccharin. Formulations can be adjusted for osmolarity.

[0138] Also included are solid form preparations that are intended to be converted, shortly before use, to liquid form preparations for oral administration. Such liquid forms include solutions, suspensions, and emulsions. These preparations may contain, in addition to the active component, colorants, flavors, stabilizers, buffers, artificial and natural sweeteners, dispersants, thickeners, solubilizing agents, and the like.

[0139] Oil suspensions can contain a thickening agent, such as beeswax, hard paraffin or cetyl alcohol. Sweetening agents can be added to provide a palatable oral preparation, such as glycerol, sorbitol or sucrose. These formulations can be preserved by the addition of an antioxidant such as ascorbic acid. As an example of an injectable oil vehicle, see Minto, J.

Pharmacol. Exp. Ther. 281 :93-102, 1997. The pharmaceutical formulations described herein can also be in the form of oil-in-water emulsions. The oily phase can be a vegetable oil or a mineral oil, described above, or a mixture of these. Suitable emulsifying agents include naturally - occurring gums, such as gum acacia and gum tragacanth, naturally occurring phosphatides, such as soybean lecithin, esters or partial esters derived from fatty acids and hexitol anhydrides, such as sorbitan mono-oleate, and condensation products of these partial esters with ethylene oxide, such as polyoxyethylene sorbitan mono-oleate. The emulsion can also contain sweetening agents and flavoring agents, as in the formulation of syrups and elixirs. Such formulations can also contain a demulcent, a preservative, or a coloring agent.

[0140] The pharmaceutical compositions described herein are preferably in unit dosage form. In such form the preparation is subdivided into unit doses containing appropriate quantities of the active component. The unit dosage form can be a packaged preparation, the package containing discrete quantities of preparation, such as packeted tablets, capsules, and powders in vials or ampoules. Also, the unit dosage form can be a capsule, tablet, cachet, or lozenge itself, or it can be the appropriate number of any of these in packaged form.

[0141] Some compositions may have limited solubility in water and therefore may require a surfactant or other appropriate co-solvent in the composition. Such co-solvents include:

Polysorbate 20, 60 and 80; Pluronic F-68, F-84 and P-103; cyclodextrin; polyoxyl 35 castor oil; or other agents known to those skilled in the art. Such co-solvents are typically employed at a level between about 0.01 % and about 2% by weight.

[0142] Viscosity greater than that of simple aqueous solutions may be desirable to decrease variability in dispensing the formulations, to decrease physical separation of components of a suspension or emulsion of formulation and/or otherwise to improve the formulation. Such viscosity building agents include, for example, polyvinyl alcohol, polyvinyl pyrrolidone, methyl cellulose, hydroxy propyl methylcellulose, hydroxyethyl cellulose, carboxymethyl cellulose, hydroxy propyl cellulose, chondroitin sulfate and salts thereof, hyaluronic acid and salts thereof, combinations of the foregoing, and other agents known to those skilled in the art. Such agents are typically employed at a level between about 0.01% and about 2% by weight. Determination of acceptable amounts of any of the above adjuvants is readily ascertained by one skilled in the art.

[0143] The compositions of the present invention may additionally include components to provide sustained release and/or comfort. Such components include high molecular weight, anionic mucomimetic polymers, gelling polysaccharides and finely-divided drug carrier substrates. These components are discussed in greater detail in U.S. Pat. Nos. 4,91 1,920; 5,403,841 ; 5,212,162; and 4,861,760. The entire contents of these patents are incorporated herein by reference in their entirety for all purposes.

[0144] Pharmaceutical compositions described herein include compositions wherein the active ingredient (e.g. vaccine compositions described herein, including embodiments) is contained in a therapeutically or prophylactically effective amount, i.e., in an amount effective to achieve its intended purpose. The actual amount effective for a particular application will depend, inter alia, on the condition being treated. When administered in methods to treat a disease, such compositions will contain an amount of active ingredient effective to achieve the desired result, e.g., prevent Herpes virus (e.g. HSV, HHV-1, HHV-2, HHV-3, HHV-4, HHV-5, HHV-6, HHV- 7, or HHV-8) infection, prevent HSV (e.g. HSV1 and/or HSV2) infection, prevent HCMV infection and/or reducing, eliminating, or slowing the progression of disease symptoms (e.g. Herpes virus (e.g. HSV, HHV-1, HHV-2, HHV-3, HHV-4, HHV-5, HHV-6, HHV-7, or HHV-8) infection, HSV (e.g. HSV1 and/or HSV2) infection, or HCMV infection). Determination of a therapeutically or prophylactically effective amount of a composition of the invention is well within the capabilities of those skilled in the art, especially in light of the detailed disclosure herein.

[0145] The dosage and frequency (single or multiple doses) administered to a mammal can vary depending upon a variety of factors, for example, whether the mammal suffers from another disease, and its route of administration; size, age, sex, health, body weight, body mass index, and diet of the recipient; nature and extent of symptoms of the disease being treated (e.g. HV (e.g. HSV, HHV-1, HHV-2, HHV-3, HHV-4, HHV-5, HHV-6, HHV-7, or HHV-8) infection, HSV (e.g. HSV1 and/or HSV2) infection, or HCMV infection), kind of concurrent treatment, complications from the disease being treated or other health-related problems. Other therapeutic regimens or agents can be used in conjunction with the methods and compositions of Applicants' invention. Adjustment and manipulation of established dosages (e.g., frequency and duration) are well within the ability of those skilled in the art.

[0146] For vaccine compositions described herein, the therapeutically effective amount can be initially determined from cell culture assays. Target concentrations will be those concentrations of active composition(s) that are capable of achieving the methods described herein, as measured using the methods described herein or known in the art.

[0147] As is well known in the art, therapeutically or prophylactically effective amounts for use in humans can also be determined from animal models. For example, a dose for humans can be formulated to achieve a concentration that has been found to be effective in animals. The dosage in humans can be adjusted by monitoring compositions effectiveness and adjusting the dosage upwards or downwards, as described above. Adjusting the dose to achieve maximal efficacy in humans based on the methods described above and other methods is well within the capabilities of the ordinarily skilled artisan.

[0148] Dosages may be varied depending upon the requirements of the patient and the composition being employed. The dose administered to a patient, in the context of the present invention should be sufficient to effect a beneficial therapeutic or prophylactic response in the patient over time. The size of the dose also will be determined by the existence, nature, and extent of any adverse side-effects. Determination of the proper dosage for a particular situation is within the skill of the practitioner. Generally, treatment is initiated with smaller dosages which are less than the optimum dose of the compound. Thereafter, the dosage is increased by small increments until the optimum effect under circumstances is reached.

[0149] Dosage amounts and intervals can be adjusted individually to provide levels of the administered composition effective for the particular clinical indication being treated or prevented. This will provide a therapeutic or prophylactic regimen that is commensurate with the severity of the individual's disease state.

[0150] Utilizing the teachings provided herein, an effective prophylactic or therapeutic treatment regimen can be planned that does not cause substantial toxicity and yet is effective to treat the clinical symptoms demonstrated by the particular patient. This planning should involve the careful choice of active composition by considering factors such as composition potency, relative bioavailability, patient body weight, presence and severity of adverse side effects, preferred mode of administration and the toxicity profile of the selected agent. This planning may include a prime boost vaccine administration as described herein. [0151] The ratio between toxicity and therapeutic effect for a particular composition is its therapeutic index and can be expressed as the ratio between LD ₅₀ (the amount of composition lethal in 50% of the population) and ED5 ₀ (the amount of composition effective in 50% of the population). Compositions that exhibit high therapeutic indices are preferred. Therapeutic index data obtained from cell culture assays and/or animal studies can be used in formulating a range of dosages for use in humans. The dosage of such compositions preferably lies within a range of plasma concentrations that include the ED5 ₀ with little or no toxicity. The dosage may vary within this range depending upon the dosage form employed and the route of administration utilized. See, e.g. Fingl et al, In: THE PHARMACOLOGICAL BASIS OF THERAPEUTICS, Ch.1, p.l, 1975. The exact formulation, route of administration and dosage can be chosen by the individual physician in view of the patient's condition and the particular method in which the composition is used. III.

V. Examples:

[0244] Several subunit vaccines have been clinically tested for efficacy, and significant protection was not achieved until HSV glycoprotein D2 (gD2), which can elicit neutralizing antibodies, was formulated with a Thl promoting adjuvant containing monophosphoryl lipid A (MPL) and alum (MPL/Alum). In the first large trial involving HSV-2 discordant couples, this vaccine was protective against disease only in HSV-1 and -2 seronegative women. However, in a follow-up phase III study, this vaccine showed limited protection against genital disease caused by HSV-1 and no protection against HSV-2 disease. [0245] The limited efficacy of these vaccines suggests that neutralizing antibodies may be necessary, but alone, appear insufficient for a vaccine development strategy (2). Thus, without being bound by any particular theory, T cell responses is likely a necessary component to efficacious vaccine development. In the mouse intravaginal HSV-2 challenge model, CD4 ⁺ T cells and IFN-γ are important mucosal effectors (19) and CD8 ⁺ T cells are associated with control of ganglionic infection (14). Additionally, CD4 ⁺ T cell loss correlates with HSV-2 shedding in HIV- 1 -infected individuals, and HSV-2-specific CD4 ⁺ and CD8 ⁺ T cells localize to genital herpes lesions and can clear infected skin keratinocytes (15, 30). Recent transcriptional analysis of CD8+ T cells residing in biopsies of resolved genital lesions at the dermal-epidermal junction proximal to sensory neuron endings demonstrated highly expressed genes for activation, proliferation, antiviral activity, and metabolism, suggesting an active role of these resident T cells for HSV-2 immunosurveillance (23). Together, these data suggest that an effective HSV-2 vaccine likely relies on robust induction of both HSV-2-specific antibody and T cell responses.

[0246] The unique platform discovered herein works for vaccines that can be used for the treatment or prevention of herpesvirus infections. Principles used for making vaccines against acute virus infections (i.e. influenza) cannot be used for designing vaccines against the herpesviruses, which cause persistent infections. In vaccine development for acute viruses, a significant inclusion criterion has been which given viral protein can generate a strong antibody or T-cell response during natural infection. In contrast, immunity following natural infection of persistent viruses may suppress dissemination of the virus and disease, but the virus persists. The herpesviruses are masters at immune evasion and can prevent the host from mounting a fully protective response. During persistent viral infections, the most visible populations of immune cells in infected individuals may be immunodominant, but not immunoprotective. Thus vaccination must be more effective in generating protection than natural infection. In this regard, the identified targets of the CD4 and CD8 T cells that are dominant specifically in HSV seropositive/asymptomatic individuals and HSV exposed/seronegative subjects are likely important. [0247] While past studies into the specificities of T cells against HSV have identified several viral antigens that are elicited in seropositive individuals, more recent studies have identified T cell specificities that predominate in either asymptomatic individuals or HSV exposed individuals who remained seronegative, do not shed virus, but have HSV specific T cells (reviewed in (16)). Notably, among the T cell specificities identified are those against the immediate early (IE) HSV proteins ICPO (ubiquitin ligase) and ICP4 (transcriptional activator), with CD4+ and CD8+ T cells that react to epitopes found from these IE antigens of both HSV-2 and HSV-1 (16). In addition, HCMV homolog proteins such as IE1 and IE2 likely react in a similar manner. Thus, eliciting immunogenic response using immediate early proteins results in eliciting 1) protective T cells against ICPO and ICP4 (and IE1 and IE2) as well as 2) protective T and B cell responses to gD2 (or gB), and 3) a broad range of T and B cell responses against an inactivated HSV-2 particle (or HCMV particle) in adjuvant vaccine that has been demonstrated to be highly protective in mouse and guinea pig models. Significantly enhanced control of virus after either prophylactic or therapeutic vaccination can be achieved by providing virus specific immunity both at the mucosal site of entry as well as at the ganglia/mucosal interface. [0248] Applicants discovered, inter alia, that the combined use of novel T cell antigens, such as gD2, gB, ICPO, ICP4, IE1 and IE2, with a highly protective viral particle boost in an adjuvant contributes to the first significant protection against HSV-1 and -2 in clinical trials. ICPO and ICP4 have been strongly implicated to be key T cell targets in individuals that are protected against either symptomatic GH or in HSV exposed but seronegative individuals. In addition, it has recently been reported that ICP4 can contribute to a protective, therapeutic HSV-2 vaccine in guinea pigs (25). These IE proteins also have a potential advantage as target antigens due to their immediate expression after viral infection allowing cytotoxic T cells to lyse infected cells before expression of immune evasive proteins and production of daughter virus (16). gD2 is a major target of neutralizing antibody. Furthermore, heterologous prime-boost immunization has been shown in animal models and clinical trials to elicit broader and more potent immune responses and increased protection (18), including the first positive protection data for a vaccine against HrV-1 (12). Thus, it is likely that antibody and T cell specificities in addition to those that are elicited by mono- or divalent subunit vaccines are needed for optimal neutralization of virus and elimination of infected cells. Indeed, a highly protective Hepatitis A virus vaccine that is formalin-inactivated and aluminum hydroxide adsorbed is one example of an inactivated viral vaccine where this strategy has been successful (24). Additionally, the inactivated HSV-2 boost contains the highly immunogenic Thl adjuvant MPL and aluminum hydroxide (licensed in Cervarix) which enhances both antibody and T cell responses.

[0249] A successful vaccine against HSV disease and shedding should elicit both protective T cell and antibody responses. Combined with recent data demonstrating the presence of T cells specific for the IE proteins ICPO and ICP4 in asymptomatic/seropositive or in seronegative, HSV-2 exposed populations make these, and other immediate early proteins, highly attractive candidate antigens. Herein, it was discovered that cell immunity against ICPO and ICP4 and immunity against gD2 can significantly augment the already high-level protection that is elicited by inactivated HSV-2 particles in MPL/Alum adjuvant.

[0250] Immunization by DNA prime-inactivated virus particle in adjuvant boost is highly protective against primary and recurrent genital HSV-2. Because of the importance for T cell mediated immunity in the control of HSV-2 infection as shown by both animal models and clinical data, the conserved, essential genes of HSV-2 might also provide T cell-mediated protection for both HSV and HCMV (20). To measure protection against both primary and recurrent infection and disease, a guinea pig model was utilized to evaluate the ability of DNA priming with candidate T cell targets including UL5 (helicase-primase) and UL30 (DNA polymerase) or UL29 (single stranded DNA binding protein) and UL52 (another subunit of the helicase-primase) to augment the protection provided by subsequent boosts with inactivated HSV-2 particles (FI-HSV2). The FI-HSV2 was formulated with a MPL/Alum adjuvant and a plasmid expressing the truncated, secreted form of gD2 (gD2t) was included in the DNA prime. Immunization with gD2t, UL5, UL30 DNAs - FI-HSV2 immunized animals was highly protective against both acute and recurrent lesions with a 97% reduction in the number of days with recurrent lesions after i.vag. challenge when compared with mock controls (FI-Mock). Notably, this group also had the lowest number of days with any level of recurrent disease compared to either the Mock or gD2 subunit control groups. Based on these results with DNA priming with the non-structural virus antigens, T cell responses to relevant T cell antigens of HSV-2 were examined for the ability to augment the protection afforded by the inactivated virus particle vaccine.

[0251] The FI-HSV2/MPL/Alum component alone was reasonably protective. However, to simplify the vaccination regimen, the purity and delivery of the FI-HSV2 was enhanced and optimize. Herein, a rapid method for producing HSV-2 was developed that greatly increased the HSV-2 particle to protein ratio. Immunization with these formalin treated particles in

MPL/Alhydrogel provided significant 3 Log reductions in vaginal virus titers at the peak of shedding after both short-term (3 week) or long-term (9 week) challenge (21). To test the protection of this preparation against challenge and re-challenge, groups of mice were immunized with the highly pure FI-HSV2 with MPL and alum adjuvants Alhydrogel (Alh) and Adju-Phos (AdP). Significantly, approximately 3 Log reductions in the peak vaginal virus titers relative to mock controls were found in all of the FI-HSV2 groups. Indeed, 5 of 8 of the FI- HSV2/MPL/Alh i.m. group were completely protected against detectable vaginal virus after both challenge and long-term re-challenge. These results are striking in that protective immunity was durable enough to completely protect against virus shedding after a second, long-term lethal challenge.

[0252] Formulation with MPL/Alum dramatically enhances immunogenicity and protection from challenge of the inactivated HSV-2 particle vaccine. The inactivated or solubilized envelope glycoprotein HSV-2 vaccines that were previously tested in human subjects were formulated either without adjuvant or with alum only, and these formulations showed only limited immunogenicity and protective efficacy (29). We therefore examined the contribution to immunogenicity and high level protection that the MPL/Alum provides and characterized the types and levels of immune responses in mice. Mice were immunized either i.m. or s.c. with inactivated HSV-2 particles in either phosphate buffered saline (DPBS) or formulated with MPL and Alhydrogel (A1H). We found that formulation of inactivated HSV-2 particles with

MPL/Alhydrogel and i.m. delivery resulted in high levels of virus specific CD4+/IF -g+ T cells, high levels of total IgG; a high-level, balanced IgGl and IgG2a response; and high levels of virus neutralizing antibodies. This formulation and route resulted in the high levels of protection against acute disease, peak virus shedding, and latent virus load and HSV-2 DNA in DRG, with the majority of mice completely protected against vaginal virus shedding and all mice protected from measurable HSV-2 DNA in ganglia. [0253] An efficacious herpes simplex virus vaccine was developed consisting of highly purified inactivated HSV-2 virions, which contain over 50 different proteins that can generate an immunological response (rather than using just a single glycoprotein). Importantly, the virions are specifically formulated in MPL/Alum adjuvant for the vaccine. The formulation with the adjuvants is the critical component for the highest level of protective efficacy. In some cases, this vaccine can be administered as part of a heterologous prime boost with DNA encoding viral proteins in the priming step.

[0254] Protection against HSV-2 shedding in guinea pigs can be significantly augmented by the addition of a recombinant-Herpes virus proteins, such as recombinant gD2 protein to the inactivated HSV-2 particle in the vaccine composition including MPL/Alum. It was also discovered that a higher purity inactivated HSV-2 particle in vaccine composition provides complete protection against lesion development after both challenge and long-term (> 4 months) re-challenge and can result in very low-level or undetectable (<4 PFU) virus shedding following both challenges. In addition, complete protection against lesion development, >3 Log reductions in virus replication, and rapid clearance of infectious virus was demonstrated following heterologous challenge with each of 2 additional U.S. strains of HSV-2. The addition to the above vaccine of a 10 to 50-fold excess (the excess is relative to the amount of viral protein in the inactivated virus preparations) of soluble specific proteins encoded by the virus that generate neutralizing antibodies and directed T cell responses, such as envelope and immediate early proteins would increase the protective efficacy.

[0255] Guinea pigs were vaccinated 3 times as follows: mock virion in MPL/Alum;

inactivated virus (FI-HSV2) in MPL/Alum; gD2 in MPL/Alum; and FI-HSV2 plus gD2 in MPL/Alum. They were then challenged intravaginally with HSV-2, and viral shedding was measured. The data show the amount of virus detected at the peak of the infection. See Figure 1. We found that adding HSV-2 glycoprotein D to the vaccine greatly increases protective efficacy and generates sterilizing immunity in 40% of guinea pigs. The remaining animals show even greater reduction in titer than achieved with the inactivated virus or gD2 alone in adjuvant. Without being bound by any particular theory, the vaccine efficacy appears based on the demonstrated importance of T cells for eradication of infected cells. This likely involves the addition of the HSV-2 proteins (e.g. ICP0 and ICP4) that are key T cell targets found in individuals who are infected but asymptomatic or in HSV-2 exposed/seronegative individuals. It is also likely that a similar response would be obtained in HCMV individuals using homologous immediate early proteins such as IE1 and IE2. The proteins are administered as part of a prime- boost vaccination to augment the protective T cell and antibody responses that are elicited by the inactivated virus alone (plus gD2) in adjuvant. With neutralizing and cellular responses to these antigens, it may be possible to develop a prophylactic and therapeutic vaccine for humans that controls virus both at the mucosal site of entry during the initial infection as well as at the ganglia/mucosal interface during reactivation in already infected individuals.

[0256] Using homologous and heterologous prime-boost combinations may optimize T cell responses against ICPO and ICP4 in the mouse and determine whether protection afforded by the been reported to reactivate latent HSV (13), null mutations were introduced to allow for their eventual clinical use. Specifically, the following mutations were introduced to inhibit function: 1) ICP4, express only the C terminal half that has peptides recognized by seropositive individuals (aa 600 to 1318) and change aa 1063 to 1070, i.e., ADWPADGP to CAWPAAAP which completely inactivates function (6); and 2) ICPO, mutate the RING finger (which confers E3 ubiquitin ligase activity) at C126G and C166A to abrogate latent virus reactivation or transcription (10). The production of high purity HSV-2 virions for inactivation by release from infected Vero cells by dextran sulfate, subsequent purification, and formalin inactivation is as previously described (21, 22).

[0257] Formulations for homologous or heterologous prime-boost immunizations are as follows. For DNA vaccination, 20 μg of each endotoxin-free gD2, ICP4, and ICPO plasmid (or 60 μg of empty pVAX1.2 vector as control) are mixed in Tris-buffered saline for i.m. injection into the tibialis anterior. To formulate inactivated virus, gD2 protein, ICPO protein, and ICP4 protein with MPL/Alhydrogel, the inactivated HSV-2 (10 ⁷ PFU equivalents per dose, ca. 0.5 -1 μg protein), an equal volume of inactivated Mock, or gD2, ICPO and ICP4 proteins (5 μg of each protein per dose) is diluted with DPBS and MPL (Sigma, 12.5 μg per dose) and Alhydrogel (125 μg equivalent to ca. 54 μg Al per dose) is added and mixed to facilitate adsorption prior to i.m. immunization as above. Groups of mice are given homologous or heterologous prime-boost immunizations, 4 weeks apart as follows: 1) pVAX - inactivated Mock negative control, homologous groups 2) inactivated HSV-2, 3) ICPO + ICP4 DNAs, 4) gD2 + ICPO + ICP4 DNAs, 5) inactivated HSV-2 + ICPO + ICP4 protein, 6) inactivated HSV-2 + gD2 + ICPO + ICP4 protein, or heterologous groups 7) ICPO + ICP4 DNA/inactivated HSV-2, 8) gD2 + ICPO + ICP4 DNAs/inactivated HSV-2, 9) ICPO + ICP4 DNA/inactivated HSV-2 + ICPO + ICP4 protein, or 10) gD2 + ICPO + ICP4 DNAs/inactivated HSV-2 + gD2 + ICPO + ICP4 protein.

[0258] Blood samples (0.2 mL) are collected by orbital bleed: 1) one day prior to the second immunization; 2) one day prior to HSV-2 challenge and 3) one day prior to euthanasia. Immune sera are analyzed for HSV-2 virion-specific IgG, IgGl, and IgG2a ELISA, gD2-specific IgG ELISAs, and neutralizing antibody assays, which are performed essentially as described (22). Vaginal washes and measurement of mucosal IgG and IgA are performed essentially as described (27). [0259] To evaluate cellular immune responses, 4 mice were sacrificed 10 days following the last immunization and another 4 mice were sacrificed 5 days post-infection to assess boosting of primed cellular responses by challenge infection. ELISPOT assay detecting IFN-ywere performed essentially as described (1). Antigen selection for the ELISPOT assay includes 15- mer peptides overlapping by 11 aa of gD2, ICPO, and ICP4 proteins as presented by the vaccines. For groups immunized with inactivated HSV-2, splenocytes are stimulated with UV-inactivated HSV-2 as described (5). To confirm whether T cell responses are either CD4 ⁺ and/or CD8 ⁺ in origin, splenocyte populations are enriched for the specific T cell population using Dynal beads (Invitrogen) according to manufacturer's instructions.

[0260] On days -7 and -1 relative to challenge, the remaining 8 mice from each group are treated with medroxyprogesterone. Three weeks after the last immunization, mice are intravaginally (i.vag.) challenged with virus (9). Briefly, the mice are inoculated by micropipette- based instillation of 15 of virus suspension containing 10 LD ₅₀ doses of HSV-2 strain G into the vaginal vault.

[0261] Vaginal washes are collected 1 day postchallenge for cytometric bead array analysis of Thl/Th2 cytokines (eBiosciences) to quantify and characterize the rapid mucosal cytokine response to HSV-2 among vaccine groups.

[0262] Acute phase disease and survival are assessed as described (21). Animals are scored daily for disease up to 21 days post challenge based on the published severity scale and vaginal swabs are collected on days 2 and 4 postchallenge and stored for high sensitivity (2 PFU per swab) plaque assay on Vero cells (22).

[0263] The significance of the survival data is calculated using Kaplan Meier Log Rank test and/or Fisher's exact test. Total disease burden is calculated by disease score area under the curve (AUC). CD4+ and CD8+ IFN-g ELISPOT levels, total disease burden, vaginal virus titers, vaginal cytokine levels, and antibody measurements are compared by Kruskal Wallis nonparametric analysis of variance plus Dunn's pairwise nonparametric comparison tests.

[0264] The guinea pig model mimics human HSV-2 infection and disease as infected hosts have episodes of recurrent disease and lesions. The frequency of recurrent episodes was shown to increase with the level of HSV-2 DNA load established in DRG (17). However, vaccine induced responses were shown to differentially protect against recurrent disease and virus shedding irrespective of DNA load (4). We found that immunization of guinea pigs with inactivated HSV-2/MPL/Alhydrogel resulted in protective responses against acute disease and reduced latent HSV-2 DNA in DRG (22). Animals that had received prior priming with plasmid DNAs expressing gD2 and conserved, essential HSV-2 proteins UL5 and UL30 showed the greatest reductions in all recurrent HSV-2 disease (22). The advantages of co-immunization with gD2 and ICPO and ICP4 may be fully realized during the recurrent phase since specific T cell immunity may provide additional control of ganglionic virus or limit the spread of virus during recurrent infection.

[0265] Groups of 10 female Hartley guinea pigs/group, 4-6 weeks of age, (300-400 g) are immunized in heterologous or homologous formats. For DNA vaccination, 20 μg of each endotoxin-free gD2, ICP4, and ICPO plasmid (or 60 μg of empty pVAX1.2 vector as control) are mixed in Tris-buffered saline for i.m. injection into the tibialis anterior. Protein-based vaccines are given by i.m. injection in the tibialis anterior with either 10 ^s PFU equivalents of inactivated HSV-2, an equal volume of inactivated mock, or 5 μg each of gD2, ICPO, and ICP4 proteins. MPL/Alhydrogel groups receive 50 μg MPL and 500 μg of Alhydrogel (equivalent to 238 μg Al). Groups are given homologous or heterologous prime-boost immunizations, 4 weeks apart as follows: 1) pVAX - inactivated Mock negative control, homologous groups 2) inactivated HSV- 2, 3) ICPO + ICP4 DNAs, 4) gD2 + ICPO + ICP4 DNAs, 5) inactivated HSV-2 + ICPO + ICP4 protein, 6) inactivated HSV-2 + gD2 + ICPO + ICP4 protein, or heterologous groups 7) ICPO + ICP4 DNA/inactivated HSV-2, 8) gD2 + ICPO + ICP4 DNAs/inactivated HSV-2, 9) ICPO + ICP4 DNA/inactivated HSV-2 + ICPO + ICP4 protein, or 10) gD2 + ICPO + ICP4

DNAs/inactivated HSV-2 + gD2 + ICPO + ICP4 protein. [0266] Blood samples (0.2-0.3 mL) (saphenous vein puncture) are collected: 1) one day prior to each of the two immunizations; 2) one day prior to HSV-2 challenge and 3) one day prior to euthanasia. Immune sera are stored at -20 °C until testing for HSV-2 virion-specific and gD2- specific IgG, IgGl, and IgG2 ELISA titers, and for HSV-2 neutralizing antibody by plaque reduction as described (22). Vaginal washes and measurement of mucosal IgG and IgA are performed essentially as described (27). Three weeks after last immunization, guinea pigs are anesthetized and i.vag. challenged with 5 x 10 ⁵ PFU of HSV-2 strain G by means of micropipette and sterile, wide-bore tip. [0267] A vaginal wash is performed on anesthetized guinea pigs on day 1 postchallenge for ELISA determination of IFN-γ and IL-2 levels using a guinea pig specific ELISAs (Uscn Life Sciences, Inc.) following manufacturer's protocols.

[0268] Efficacy is evaluated in acute phase (0-14 days post-challenge) lesion formation and viral shedding as described (22). Animals are scored daily for acute lesion formation for 14 days post-challenge based on the published severity scale. To measure acute vaginal viral shedding, vaginal swabs are collected on days 1, 3, 5, 7, 9, and 12 post-challenge and stored in buffer at -80 °C until titration by plaque assay on Vero cell monolayers. To measure recurrent shedding, daily swabs are collected for 21 days starting 4 weeks after challenge and stored for qPCR

quantification of HSV-2 DNA. Animals are scored daily for lesion formation during the recurrent phase (days 15 - 60). At the end of the experiment, the lumbosacral dorsal root ganglia (DRG) are isolated and the amount of HSV-2 latent DNA determined by qPCR as described (22).

[0269] Guinea pigs are i.vag. infected with 5 x H PFU of HSV-2 strain G and scored for disease. Surviving animals are randomized into 10 groups by matched disease severity (area under the curve) and immunized on days 21 and 35 as above. Lesions are scored to day 90 postinfection to measure the cumulative number of recurrent lesions and total disease burden in each immunization group. Swabs are collected daily for 1 week before and 3 weeks after the second immunization to measure shedding frequency by qPCR quantification of HSV-2 DNA. At the conclusion of the experiment, animals are sacrificed and DRGs are harvested and stored for qPCR as above.

[0270] Protection between groups is assessed by statistical analyses (2 -tailed) of the following outcomes of infection. Infection rates, rates of primary lesion development, and rates of recurrent lesion development are each compared by Fisher's exact test. Primary disease burden (as measured by area under the curve (AUC) of disease severity scores, number of recurrent lesion episodes, recurrent disease days, summed recurrent disease scores, vaginal virus shedding levels through day 12, and HSV-2 DNA copies in swabs and DRG are analyzed by Kruskal-Wallis nonparametric one-way analysis of variance followed by pair- wise comparisons using Dunn's multiple comparison tests.
