OBJECTIVE: the study aims to evaluate the hepatitis B vaccination coverage among people younger than 20 years in 22 cities of the Third Regional Health Office, during 2007. METHODOLOGY: data were obtained from the Information System for Evaluating the Immunization Program; hepatitis B vaccination coverage was defined as the percentage of the target-population that received the third dose of the vaccination scheme; the denominator employed for children younger than five years was the number of livebirths obtainedfrom the Live Birth Information System; for the remaining age groups, the authors used the population estimative of the Brazilian Institute of Geography and Statistics Foundation. RESULTS: the results of the study show high vaccination coverage among children under one year of age; however, as age increases, the vaccination coverage shows a reduction in almost all municipalities, pointing out to a need for reevaluation of current strategies employed by health services. CONCLUSION: this study may serve as a guide for the planning of strategic actions of vaccination in the public health services of the municipalities in order to achieve broad vaccination coverage and, periodically, monitor its development.
