Many healthcare workers (HCWs) remain unvaccinated against hepatitis B virus (HBV). Even vaccinated HCWs may have low anti-HBs titers, necessitating booster doses and screening.
Area of Science:
- Occupational health
- Immunology
- Infectious disease epidemiology
Background:
- Healthcare workers (HCWs) face a high risk of hepatitis B virus (HBV) infection.
- Assessing HBV immunization and anti-HBs titers in HCWs is crucial for occupational safety.
Purpose of the Study:
- To evaluate the hepatitis B virus (HBV) immunization status among healthcare workers (HCWs).
- To determine the anti-hepatitis B surface antibody (anti-HBs) titers in vaccinated HCWs.
Main Methods:
- Prospective examination of anti-HBs titers in 464 enrolled HCWs.
- Comparison of titers based on vaccination timing (within or beyond 5 years) and booster dose status (<1 year vs. >1 year).
Main Results:
- 49.6% of HCWs were vaccinated, with doctors showing the highest vaccination rate (92.5%).
- Among vaccinated HCWs, 59.2% had anti-HBs titers >100 mIU/mL, but 30% had titers <10 mIU/mL.
- Mean anti-HBs titers were significantly lower in those vaccinated >5 years ago and those who received a booster dose >1 year ago.
Conclusions:
- A substantial proportion of HCWs are unvaccinated or have suboptimal anti-HBs titers.
- Routine anti-HBs titer measurement, booster administration, and HBsAg screening should be mandatory for HCWs.
- Ensuring adequate HBV immunity in HCWs is essential to prevent occupational transmission.
