| Outline of Final Research Achievements |
Annual flu vaccination protects from seasonal influenza virus infection but doesn’t fully have effects on emerging new viruses such as avian H5 influenza virus. Vaccine against broad spectrum of influenza virus strains is ideal. Twenty years ago, a Japanese scientist isolated a “universal antibody” in the first time in the world. This antibody can block infections of several influenza virus strains. Using this unique antibody as a template, we design artificial peptide antigen in silico for universal vaccine. We expect that this antigen can induce the universal antibody-like antibodies to protect from various influenza virus strains. We gained a proof-of-concept data that some of synthetic peptides bind to the universal antibody and could induce neutralizing antibodies against two influenza virus strains.
