Abstract:
The study presented here was conducted in order to evaluate the impact of Norway's childhood immunization program against measles, which was implemented in 1969. In the study, the level of measles immunity was measured among 1,405 military conscripts belonging to the first childhood immunization cohorts that were offered two doses of the measles, mumps and rubella vaccine. The overall seroprevalence of measles antibodies in this cohort was 89.3%. Two commercially available antibody assays were used, and the discordance between the two assays was 10.5%. Similar levels of immunity to measles were detected in earlier studies of Norwegian conscripts belonging to different childhood immunization cohorts.
