title: [Immunoepidemiological observations on the duration of post-vaccinal immunity in children vaccinated against measles].
abstract: In the course of 4 years the authors carried out an immunological and epidemiological observation over 4719 children which attended creches, kindergartens and schools, and were vaccinated with live measles vaccines L-16 and ASC in 1967--1972. A stable persistence of immunity was revealed in the majority of children vaccinated against measles which responded to the vaccination by the formation of humoral antibodies. Among these groups an insignificant number of persons with the appearance of measles sensitivity was noted during the observation period. The quality of the preparation, conditions of its storage, use, and different errors during the vaccination influenced the efficacy of the vaccination. Children immunized with the low-immunogenic series of the vaccine whose blood sera failed to display any specific antibodies in the reaction with 1 AU of the antigen, as a rule, were the ones that contracted the disease.
