STUDY OF THE EFFECT OF MEASLES VACCINATION ON THE EPIDEMIC PROCESS OF THE DISEASE

Abstract

Before measles vaccination programs were introduced, measles was almost universal among children. With the introduction of measles vaccination and the increase in vaccination coverage, the incidence of this disease has decreased in the years of the outbreak of the disease, and the period of repeated registration of the epidemic situation has been extended. Measles has been eliminated in many countries by achieving a very high level of immunity to measles in the population, but periodic measles outbreaks may re-emerge if this level of immunity is not maintained.
