A Study of HIV in Newly Infected Individuals

The purpose of this study is to see how HIV reacts in the immune systems of patients who have recently been infected with HIV. This study also examines HIV's resistance to anti-HIV drugs in newly infected patients. Certain populations are good candidates for participation in HIV vaccine trials. These groups include men who have sex with men, IV drug users, and women at risk of getting HIV through heterosexual contact. Learning how HIV behaves in these populations once they become infected can help with the planning of future HIV vaccine studies.
