Abstract

The risk of acquiring hepatitis B infection through exposure for blood or its product is highest among health care workers. The most important approach for the prevention of occupational HBV infection is the use of hepatitis B vaccine among HCWs at risk. The present study was undertaken to assess the immune status of HBV vaccinated health care workers. A total of 268 HCWs of Adichunchanagiri Hospital and Research Centre attached to AIMS, B.G.Nagara were enrolled for the study .The study group includes doctors (113), medical & nursing students (61), nurses (59), technicians (15), group D workers (12) and others (8). The serum samples of the participants were tested for Anti-HBsAb levels using ELISA kit (Diasorin, Italy). Anti HBsAb titre of ≥ 10mIU/ml was considered as immune and < 10 mIU /ml as non-immune. The mean age of the study group was 29.49 years. Of the 268 participants 54.85% were female and 45.14% male. 23.5% had history of complete vaccination and 76.49% had incomplete vaccination (1/2 doses). 72.01% were immune and 27.98% non immune. There is a need for stringent and clear policies for HBV screening, vaccination and post vaccination assessment.
