Hepatitis B vaccination status and associated factors among health care workers in Burkina Faso

Introduction. The purpose of this study was to evaluate anti-HBV vaccination status and factors associated with vaccination against HBV among health care workers in Burkina Faso. Methods. In August and September 2010, we conducted a cross-sectional study on health care workers having practiced in a health facility for at least three months. Data were collected using a selfadministered questionnaire. Blood samples were collected from consenting participants to search for anti-HBs antibodies, markers of immune status. Results. A total of 452 health care workers were surveyed. Among the respondents, 47.7 % had received at least one dose of HBV vaccine. The full immunization coverage against HBV was estimated at 10.9 %. Factors associated with vaccination status were age (p = 0.005), occupation (p = 0.005), and seniority in the profession (p = 0.001). Anti-HBs was found in 61.6 % of respondents, with significant differences (p = 0.01) between subjects who received at least one dose of vaccine (76.7 %) and those who reported never having been vaccinated (50.3 %). Conclusion. Hepatitis B vaccination coverage among health care workers is low in Burkina Faso, hence the need to promote vaccination against HBV in health facilities.
