[Vaccination coverage of 2-year-old children: a cross-sectional study in the city of Barcelona].

The results of a vaccination coverage cross-sectional survey of two year old children in the city of Barcelona (Spain) are presented. A sample of the cohort born in 1986 was surveyed. Vaccination coverage is 93.16% for measles, 92.02% for mumps, 91.25% for rubella. Up to 91.25% children had received four doses of polio vaccine and 94.67% three doses, while 91.63% had received four doses of DTP vaccine and 95.06% three doses. These results suggest vaccination coverage in Barcelona has improved, but a volume of unvaccinated persons exists which, coupled with vaccine failures may allow the persistence of vaccine-preventable disease which should be eradicated.
