To study the efficacy of standard hepatitis B (HB) vaccination in methadone-maintained former intravenous drug users.
HB vaccine was administercd to subjects at 0,1 and 6 months.
Two university-affiliated methadone maintenance clinics.
Forty-three HB-unexposed former heroin addicts in methadone maintenance treatment for heroin addiction.
HB surface antibody (anti-HBs) response to the vaccine was assessed at 0,1,6 and >= 12 months ; anti-HIV-1 status was also assessed.
Thirty-seven patients (86%) completed the 6-month vaccination series.
Of the 30 anti-HIV-1 scronegative patients who then completed the entire 12-month protocol, 21 (70%) seroconverted (anti-HBs ratio>2.1) and 19 (63%) were protected (anti-HBs ratio>10).
One was HB-protected at 12 months but later lost immunity.
Ten anti-hepatitis C antibody-positive patients completed the 12-month study and six were protected ; thus, there was no significant relationship between hepatitis C status and HB vaccine respouse.
Standard HB vaccination is both feasible and effective.
