Popis: Controlled field clinical trials of Avaxim vaccine from hepatitis A (Pasteur-Merrier-Connot) were carried out in adults and children aged 3-14 years to evaluate its reactogenicity and antigenic properties. The vaccine was weakly reactogenic both in adults and children. A single injection of the vaccine resulted after 1 month in the production of anti-HAV antibodies in 77.4% initially seronegative adults and 94.5% children. In adults the mean geometrical titer of antibodies was 95 mIU/ml and in children 165 mIU/ml, which was 5-8 times higher than the protective titer. These data recommend Avaxim vaccine for practical public health.
