| Outline of Final Research Achievements |
The characteristics of natural immunity against norovirus were analyzed by long-term molecular epidemiological study involving systematic surveillance covering all age groups and routes of infection was performed in the province of Osaka, Japan.There was evidence at both the facility and individual levels that genotype-specific herd immunity lasted long enough to influence the endemic norovirus genotype in the next season. Thus, norovirus circulates through human populations in a uniquely dynamic fashion. We contribute to the basic knowledge of the norovirus vaccine development.
