[Testing for the safety, reactogenicity and antigenic properties of a live thermostable mumps vaccine made from the Leningrad-3 strain].

A live mumps vaccine (LMV) from strain Leningrad-3 with a new stabilizer LS-18 was tested for reactogenicity and antigenic potency. Examinations of vaccinated children for vaccination reactions showed its complete areactogenicity and safety. LMV induced synthesis of virus-neutralizing antibodies in 78-82% of the vaccinees.
