The human immunodeficiency virus (HIV) type 1 Tat protein plays a key role in the life cycle of the virus and in pathogenesis and is highly conserved among HIV subtypes. On the basis of this and of safety, immunogenicity, and efficacy findings in monkeys, Tat is being tested as a vaccine in phase 1 trials. Here, we evaluated the incidence and risk of progression to advanced HIV disease by anti-Tat serostatus in a cohort of 252 HIV-1 seroconverters. The risk of progression was lower in the anti-Tat-positive subjects than in the anti-Tat-negative subjects. Progression was faster in the persistently anti-Tat-negative subjects than in the transiently anti-Tat-positive subjects, and no progression was observed in the persistently anti-Tat-positive subjects.
