Awareness and Practice of Complete Hepatitis B Vaccination and Anti-HBs Testing in Vaccinated Health Care Workers .

摘要

Background: Hepatitis B is a serious and common infectious disease affecting millions of people worldwide. Health Care Workers (HCW) are at an increased risk of occupational exposure to HBV and the incidence is 2-4 times higher than in the general population. Despite potential risks, awareness and vaccine compliance is poor among the HCWs. Aim: To assess the awareness of complete Hepatitis B vaccination, anti-HBs testing & protective titres and determine the anti HBs titres amongst vaccinated HCWs. Material & Methods: A total of 500 Health care workers of both sexes in the age group from 20- 60 years vaccinated against Hepatitis B were tested for anti-HBs titres by quantitative ELISA. Results: The rate of complete immunization was 81.4% in doctors, 63.3% in nursing staff and 90% in the technical staff. Amongst the 500 participants, 70.8% had received all the doses and 29.2% incomplete doses of the vaccine. Titres of ≥ 10 mIU/ml were demonstrated in 84.4% of HCWs who received all the doses and in 65.7% those who defaulted. Conclusions: The results of the study indicate lack of awareness about complete HB vaccination and the importance of post vaccination testing in HCWs.
