title: [Comparative study of the immunogenicity of the inactivated hepatitis A vaccine Hep-A-in-vac from experimental and clinical data].
abstract: Comparative analysis of the specific activities of various batches of Hep-A-in-Vac vaccine showed that the immunologic efficacy of the agent directly depended on the content of hepatitis A virus antigen in the vaccine dose. The results of studying the immunogenicity of the agent on volunteers are compatible with the results of experimental studies and indicate that the test of guinea pigs adequately assesses this characteristic. Assessment of the immunogenic properties of Hep-A-in-Vac prepared using improved technology indicates that Russian vaccine injected three times in a dose containing at least 40 U EIA ensures 87.5% seroconversion in adult seronegative volunteers with the mean geometrical titer of antibodies to hepatitis A virus equal to 683 mIU/ml.
