Abstract
Background and Aims: the Aim of the study was to find the level of protection among the healthcare workers (nurses, doctors, housekeeping staff and general duty assistants) by doing Anti-HBsAb titer and vaccinate those who were not properly immunized against HBV infection.
Materials and Methods: The study was approved by the Institutional review board of the Hospital. The study group included doctors, nurses, technical staff and lab attendants. Anti-HBs antibody titer was done on Vitros 3600 (OCD, USA). Tests were performed according to manufacturer’s instruction. Vaccine provided was Engerix B (GSK Glaxo, Belgium). Vaccination was provided to all employees had titer below 10 miu/ml.
Results: 489 of 794(61.5%) HCW had no history of previous vaccination and only 293 (36.9%) subjects had complete vaccination. Only 60.8 % (482/794) of the total subjects had titer above 10 miu/ml and were protected against Hepatitis B. Around 80.6% (246/305) of those who were fully vaccinated and 40.8% (237/489) of those who were not vaccinated previously had protective anti-HBs titers(>10 miu/ml). Majority (86.8%, 271/312) who had titer below 10 miu/ml were unvaccinated. Two of eight employees who had history of needle stick injury in past were found non-immune to Hepatitis-B infection.
Conclusion: Despite being involved in the procedures with high chances of infections through needle stick or other exposures, only one third of health care workers were vaccinated against hepatitis B. We recommend that all the HCWs should be vaccinated for Hepatitis B and their anti-HBs levels determined at regular intervals.
