title: Active and passive immunization against HIV type 1 infection in chimpanzees.
abstract: Several vaccine strategies have been developed to prevent primary infection with human immunodeficiency virus (HIV), and some of the candidate vaccines have been tested in chimpanzees to determine their safety, efficacy, and to delineate immune correlates of protection. To date, more than 25 vaccines representing active and passive immunization strategies have been evaluated in the chimpanzee model. Efficacy of a given vaccine was based on protection against primary infection with HIV after intravenous or mucosal challenge with cell-free or cell-associated virus. Based on the results from a majority of the studies, neutralizing antibodies appear to play a major role in preventing primary infection with HIV.
