Background
Hepatitis B virus (HBV) infection is a major occupational hazard among healthcare workers (HCWs), particularly in resource‐limited settings where vaccination coverage remains low. This study aimed to assess hepatitis B vaccination coverage and associated factors among healthcare workers.
Methods
An institution‐based cross‐sectional study was conducted from September 20 to November 3, 2025, among 448 healthcare workers. Participants were selected using a census sampling method. Data were collected using a structured, pretested questionnaire and analyzed using SPSS version 25. Binary and multivariable logistic regression analyses were performed to identify factors associated with vaccination status. Statistical significance was declared at p < 0.05.
Results
Only 170 (37.9%) participants were fully vaccinated against HBV. Good knowledge and favorable attitude were observed in 68.4% participants who responded appropriately for at least 70% of knowledge related questions and 79.9% of participants who responded appropriately for at least 70% of attitude related questions. Factors significantly associated with vaccination included infection prevention training (AOR = 8.44; 95% CI: 2.00–12.65), good knowledge of HBV infection (AOR = 2.29; 95% CI: 1.60–3.11), knowledge of HBV vaccination (AOR = 4.29; 95% CI: 1.40–13.14), and favorable attitude (AOR = 3.62; 95% CI: 1.89–4.14).
Conclusion
Hepatitis B vaccination coverage among HCWs was low. Strengthening institutional vaccination programs, improving access to free vaccines, and enhancing infection prevention training are essential to improve coverage.
