Abstract:

The qualitative performance and timely completion, prior to the onset of a regular outbreak, of a triple immunization encompassing the largest number of collectives, are considered the main conditions for exposing the epidemiological effectiveness of live influenza vaccine. The results of the immunization of 12,600 adult persons, distributed among 33 separate collectives, were studied during two successive epidemics of influenza type A2 and B in January -- April 1962. In January--February 1962 in the majority of these collectives an outbreak of type A2 influenza took place, and beginning with March a wave of influenza type B emerged. During this a significantly more intense incidence rate with type A2 and B influenza was observed in the control noninoculated collectives than in the collectives which were encompassed by the almost complete administration of live influenza vaccine.
