Abstract (Summary)
ABSTRACT Study of the vaccine coverage in children below 3 years old in Catalonia. INTRODUCTION: At present vaccines available have very high proven efficacy, but effectiveness in protecting population depends not only on the efficacy of the vaccines but also of the immunization coverage being attained by vaccination programs. Universal vaccination is one of the most efficient public health strategies since it has achieved a drastic reduction in the incidence of many vaccine-preventable diseases. OBJECTIVE: The goal of this study was to assess vaccine coverage of the vaccines included in the systematic immunization schedule for children younger than 3 years in Catalonia and the variables associated with this coverage. METHODOLOGY: A retrospective transversal descriptive observational study through a stratified random survey has been carried out by sanitary region and by type of town, rural or urban. The sampled population was 630 children born in October of 2001 registered in the chosen municipalities. RESULTS: The results showed that in more than 94% of the 630 children had received 4 doses of DTPa/w and OPV, than 95% had received 3 doses of MenC, than 90% had received 4 doses of Hib and more than 98% had received one dose of MMR. No differences were detected neither among the sanitary regions of Catalonia, type of residence (urban or rural), coverage according to type of vaccine and number of doses, nor in vaccination schemes studied. Coverage in the immigrant population was lower than in the autochthonous one. Association was observed among being immigrant and showing smaller coverage, except in the case of 4 doses of OPV and of Hib. CONCLUSIONS: Homogeneity of the vaccine coverage is observed in the territory, but there is lesser coverage in the immigrant population, especially in newcomers. Follow up on vaccine coverage is essential in order to evaluate immunization programs. Efforts increasing vaccination coverage in the immigrant population and increasing the coverage of booster doses in autochthonous population have to be carried out.
