[BDSP. Notice produite par INIST YR0xN60K. Diffusion soumise à autorisation]. A measles epidemic occurred in Romania with 32,915 cases and 21 deaths reported between November 1996 and June 1998, despite high vaccination coverage since the early 1980s. Most cases were unvaccinated children aged1 year. Waning immunity was not identified as a risk factor since vaccine effectiveness was similar for children vaccinated 6-8,9-11, and 12-14 years in the past. Because specific groups were not at risk for vaccine failure, an immunization campaign that targets all school-aged children who lack two doses may be an effective strategy for preventing outbreaks. A mass campaign followed by increased first-dose coverage should provide the population immunity required to interrupt indigenous measles virus transmission in Romania.
