Audit of hepatitis B immunization at the genitourinary medicine department in Middlesbrough, UK

The outcomes of hepatitis B immunization programme at the genitourinary medicine (GUM) department in Middlesbrough during a period of five years were examined. The majority of those immunized were male homosexuals who had earlier requested an HIV test. All participants had preimmunization hepatitis B serology, and were negative. The default rate was high at 20/42 (47.6%). However, among those who completed all the processes, seroconversion rate was high at 21/22 (95.5%). The only non-responder was a man who was HIV-positive. The type of vaccine and immunization regimen are discussed.
