OBJECTIVE: to determine the prevalence of serological markers of infection by hepatitis B virus (HBV) among workers at a research institute in eastern Amazon, state of Pará, Brazil. METHODS: descriptive study, carried between 2007 and 2009, with workers who agreed to participate through interview and investigation of serological markers of hepatitis B by immu-noenzymatic techniques. RESULTS: among 528 individuals surveyed, was found the prevalence of 0,4% of surface antigen of HBV, 8.0% of antibodies against hepatitis B core antigen/antibody against the surface antigen of VHB, 2.5% antibodies against hepatitis B core isolated antigen and 28.8% antibodies against surface antigen of isolated HBV, 68.4% susceptible to HBV that corresponded to non-vaccinated individuals. CONCLUSION: the research identified inadequate prevalence of seroconversion below the average reported by the Ministry of Health, in which three doses of the vaccine should confer protection of approximately 90.0% in adults.
