[Immunoprophylaxis of epidemic parotitis].

Specific prophylaxis against epidemic parotitis is considered to be necessary. It is epidemiologically justifyable at first to conduct selective immunization with the monovaccine of children aged over one year (in creches and kindergartens) and schoolchildren (and 10-year-olds inclusively) who had had no epidemic parotitis, and later to vaccinate children over one year newly-admitted to the creches, kindergartens and schools. In order to bring to the minimum the risk of supervention of the living parotitis vaccine on the asymptomatic infectious process it is necessary to conduct the vaccination at the period between the end and the beginning of the stable seasonal rise, which in Leningrad falls on the period between the second decades of August and October.
