Hepatitis B vaccination of men who have sex with men: experience with an accelerated course of vaccination in a genitourinary medicine clinic.

An accelerated course of hepatitis B vaccination was offered to men who had sex with men attending a genitourinary medicine clinic. The uptake and completion rates of the vaccine between 1 November 2002 and 28 February 2004 were compared with data for 1994. The uptake of vaccine was significantly higher during the former audit period than the latter (310 [98%] of 315 versus 146 [74%]). There was, however, no significant difference in completion rates between the two audit periods: 220 (73%) of the 302 men who initiated the accelerated schedule, compared with 118 (81%) of the 146 men who completed the standard course in 1994. Innovative means of ensuring completion of vaccination are needed.
