Drug addicts represent the group of young adults with the lowest response to hepatitis B virus (HBV) vaccine. A study was carried out on 110 current intravenous heroin users attending the service providing assistance to intravenous drug users (IVDUs) (SERT) in Padua: 66.4% of them were found anti-hepatitis C virus (HCV)-positive and 33.6% were anti-HBc positive; 29.9% were positive for both. The subjects were vaccinated with 10 microg of yeast-derived vaccine at months 0, 1 and 2 (fast schedule). The overall response rate was 66.4%. Response seems to be affected by positivity to anti-HBc, but not to HCV infection.

Abstract
Drug addicts represent the group of young adults with the lowest response to hepatitis B virus (HBV) vaccine. A study was carried out on 110 current intravenous heroin users attending the service providing assistance to intravenous drug users (IVDUs) (SERT) in Padua: 66.4% of them were found anti-hepatitis C virus (HCV)-positive and 33.6% were anti-HBc positive; 29.9% were positive for both. The subjects were vaccinated with 10 microg of yeast-derived vaccine at months 0, 1 and 2 (fast schedule). The overall response rate was 66.4%. Response seems to be affected by positivity to anti-HBc, but not to HCV infection.
