Abstract

Introduction: The vaccination against Hepatitis B is, undoubtedly, necessary for the baby within the first year of age. It is the most effective way to prevent such disease. Checking the population is, therefore, indispensable. Objectives: Assess the one-year-of-age population in Trindade-GO, concerning Hepatitis B vaccionation cover, and analyze the indicators on that pathology. Methods and materials: The research has been taken under a retrospective epidemiologic study, with data from DATASUS information system, from 2002 to 2012. Methodological steps, such as identification of the vaccination cover evolution; comparison of unborn number with the first vaccination doses number; as well as the first doses number with the third doses number have been taken. Also the analysis of: Hepatitis B case incidence; the occurrence according to age; and the identification of deaths related to Hepatitis B. Results and discussion: A high age heterogeneity has been observed, ranging from 70.22% to 134.63%. It was found in most of the years evaluated vaccination coverage unsatisfactory. The number of unborn has been higher than the doses, except on 2011 – indication that a significant number of unborn has not received the vaccine. During six years the first does have been higher than the third ones – evidencing an interruption in the program schedule. The incidence of 90 cases is heterogeneous and with predominance of intrahepatic biliary and liver malignant neoplasm as causa mortis. Conclusion: the low coverage indicates that a substantial number of children has not been immunizied – allowing an increase on the population death and the loss of control on the malady. Verified the need to employ a best measure to ensure the application of the first dose at birth. The results hereafter may be a good help to understand the problem, as well as to promote planning and real actions of intervention.
