| Outline of Final Research Achievements |
We generated recombinant measles virus (rMV) expressing the hemagglutinin (HA) protein of HPAIV (H5), and examined protective efficacy of the candidate vaccine in the monkey infection model by the challenge with a HPAIV (H5N1). Cynomolgus monkeys inoculated with the candidate vaccine produced anti-H5 HA antibodies and recovered earlier from influenza symptoms than unvaccinated monkeys after the challenge with the HPAIV strain. In addition, vaccination tended to suppress viral shedding. Moreover, even in monkeys possessing pre-existing anti-MV antibodies, the vaccination with the candidate induced the production of antibodies against H5 HA. These results suggest that the rMV expressing H5 HA is a good candidate vaccine against HPAIV infection to reduce disease severity.
