title: Dependence on the birth season of the level of haemagglutination inhibition antibodies against Japanese encephalitis virus in the Japanese population.
abstract: According to the frequency of haemagglutination inhibition (HI) antibodies against Japanese encephalitis (JE) virus the Japanese population born during the years of JE epidemic falls into 2 groups. The population born during the epidemic season of JE (from July to October) showed a lower rate of HI antibody positivity to JE virus than those born during the non-epidemic season (from November to June). This phenomenon was not related to the birth place of investigated subjects and was not related to JE vaccination.
