Assessment of hepatitis B vaccination status among healthcare workers in South Delhi: a cross-sectional study

Background: Healthcare workers (HCWs) are at increased risk of hepatitis B virus (HBV) infection due to occupational exposure to blood and body fluids, particularly needle-stick injuries. Hepatitis B vaccination is a safe and effective preventive measure recommended for all HCWs. Methods: A hospital-based cross-sectional study was conducted in 2018 among 539 healthcare workers using a structured questionnaire. Participants included doctors (including interns and postgraduate students), nurses, laboratory technicians, and other healthcare staff exposed to blood and body fluids during patient care. Vaccination status was categorized as complete (three doses), partial (one or two doses), and unvaccinated. Data were analyzed using descriptive statistics. Ethical clearance was obtained from the Institutional Ethics Committee. Results: Among 539 participants, 379 (70.32%) were fully vaccinated, 115 (21.33%) were partially vaccinated, and 45 (8.34%) were unvaccinated. Vaccination coverage was highest among nurses (84.18%), followed by doctors and internees (69.79%) and laboratory technicians (63.46%). Coverage was lowest among other healthcare workers, with 41.07% unvaccinated. Conclusions: Although most healthcare workers were vaccinated, gaps remain, particularly among supportive staff. Strengthening institutional vaccination policies and awareness programs is necessary to achieve complete coverage and reduce occupational risk of HBV infection.
