This study will assess the efficacy of a new intradermal formulation of the trivalent inactivated influenza vaccine compared to the standard intramuscular vaccine in HIV-infected men who have sex with men in Bangkok, Thailand. Relative efficacy of the two different formulations of influenza vaccine will be assessed by comparing immunologic responses to vaccine between the two study arms.
