title: [Epidemiological effectiveness of an inactivated three-component flu vaccine with an increased concentration of hemagglutinin in the inoculation dose].
abstract: The work presents the results of the evaluation of mass immunization of working adults with inactivated trivalent influenza vaccine under the conditions of an epidemic caused by influenza viruses A (H1N1), A (H3N2) and B. This immunization produced no effect on influenza morbidity in the groups of vaccinees in comparison with those of nonvaccinated persons. The index of effectiveness was 1.0 and less. The ineffectiveness of mass immunization was due to a high level of natural immunity to influenza and the extensive use of influenza vaccine in past years.
