Brief Summary
Investigators in the Division of Infectious Diseases are carrying out a study to determine if human immunodeficiency virus (HIV)-seropositive patients receiving the Seasonal Influenza vaccination develop an adequate antibody response. The study group will consist of individuals seen in the Infectious Diseases Clinic who are HIV-seropositive and receive the Seasonal Influenza vaccine.

Outcome Measures
Primary Outcomes (1)
Change in antibody levels
The primary endpoint will be to measure the change from baseline in vaccine-strain specific antibody levels. Titers of \> or = 40 U will be considered protective and a \> 4-fold rise in antibody titer will be considered an adequate response in previously antibody-negative patients. Data from this study will assist in defining the efficacy of the influenza vaccine in the HIV-infected population and the ability of HIV-infected patients to generate an appropriate immune response, as well as maintain an appropriate response, to the influenza vaccine.
Pre-, 3 weeks post-, 3 months post- vaccine
Study Arms (1)
HIV positive
