[Vaccination coverage of school children].

The results of an immunization coverage survey among first grade schoolchildren (six-year old) in public and subsidized schools of the Sant Martí district of Barcelona (Spain) are shown. Vaccination coverage is assessed by immunization cards or other valid documents and through the computerized immunization register of the City. Estimated vaccination coverage is 76% for measles, 65.9% for rubella and 65.9% for mumps. Up to 74.7% of the children have received five doses of polio vaccine, and 83.5% at least four doses, while 72.5% have received five doses of D.T.P. or D.T. and 83.4% four doses. Slight differences among the four neighborhoods in the district are seen, probably related to socioeconomic level and to the pattern of use of health services.
