[Evaluation of mass influenza prevention effectiveness using an inactivated chromatographic vaccine in Leningrad]
Abstract:
The work presents the evaluation of the effectiveness of mass immunization with inactivated chromatographic vaccine carried out in Leningrad during the influenza A (H3N2) epidemic of 1979--1980. These prophylactic measures were shown to cause a statistically significant decrease in morbidity rate among the vaccinees and the whole population (morbidity rate decreased 1.41 times among the whole population, 1.99 times among persons aged 8 years and over and 3.1 times among the vaccinees at industrial enterprises). The economic effect of 8.4 million roubles was achieved. To evaluate the apidemiological effectiveness of the above-mentioned antiepidemic measures, an original complex of techniques has been developed; such techniques can also be used for the evaluation of other similar measures.
