Introduction: Hepatitis B (HB) vaccination for health-care workers is essential for World Health Organization’s goals achievement of viral hepatitis (VH) elimination. However, recent studies showed low vaccination adherence by these professionals and lack of knowledge about HB vaccination adherence of community health workers (CHW). Objective: To identify the adherence of CHW to HB vaccination; to determine the causes of non-adherence; to investigate whether the prevalence of vaccination is different among surveyed towns, and to verify whether years practiced as CHW have any association with vaccination adherence. Methods: This cross-sectional study included five towns (T) of a Brazilian state. Data were collected at VH educational meetings, in which CHW answered a questionnaire. The proportions Z-test and the likelihood ratio test were used for statistical analysis. Significance was set at p<0.05. Results: The sample included 516 CHW. Most CHW (86.8%) reported to have taken the vaccine, but only 59.7% affirmed having taken all doses, and 28.1% correctly answered the number of doses. 24.4% of CHW pointed the unknowing about HB vaccine importance as the main reason for non-adherence. T4 and T5 showed higher vaccination prevalence than T2 and T1. Vaccination adherence was higher among individuals with more years working as CHW. Conclusion: CHW demonstrated low adherence to HB vaccination and pointed the lack of knowledge about HB vaccine importance as the main reason for that. There were differences in vaccination prevalence among the towns and adherence was positively associated with professional experience.
