Document Type and Number:
WIPO Patent Application WO/2017/084635
Kind Code:
The present invention relates to an oral universal influenza vaccine comprising recombinant lactic acid bacteria which express proteins including but not limited to ferritin protein plus highly-conserved stem fragment of hemagglutinin (HA) proteins expressed in all known influenza viruses. The present invention also relates to the recombinant protein comprising the highly-conserved stem fragment of HA and ferritin proteins.
