Efficacy of Shanvac-B recombinant DNA hepatitis B vaccine in health care workers of Northern India.

Abstract

The presence of HBsAg in HCWs indicates that a high proportion of HCWs are infected with HBV and HCV in India. Recombinant indigenous vaccine Shanvac-B is highly efficacious in HCWs, and its immunogenicity is significantly higher in females than in males. However, pre-vaccination screening of HCWs is strongly recommended in India.
