title: [An epidemiologic and immunologic study of measles under conditions of massive immunization against that infection].
abstract: Massive measles immunization in Riga led to a marked reduction of measles incidence and to a change of the principal regularities of the epidemic process in this infection. Among those who contracted the disease there was an increase in the percentage of schoolchildren; affection with measles of children attending creches and kindergartens and the intensity of the spread of the infection in them diminished. Selective examination of the immunological efficacy of the living measles vaccine prepared of the (see article) and applied in 1967--1972 demonstrated the presence of specific stimulation of the antibody formation in about 90% of the persons vaccinated. The intensity of humoral immunity in the persons vaccinated did not diminish with the advance of time after the vaccination, and 6--7 years after the vaccination over 90% of the vaccinated individuals were reliably protected from measles. The presence of numerous negative results in carrying out the vaccinations in individual institutions is apparently attributed chiefly to disturbances of the storage regimen of transportation and of the use of the vaccine.
