HIV vaccine development

HIV Vaccine Development.

Several interesting new vaccine-related studies were presented at the 16th Conference on Retroviruses and Opportunistic Infections this year. Transmitted viruses appear to be derived from cell-free virus rather than cell-associated virus, at least in men who have sex with men. Follow-up studies from the Step (HIV Vaccine Trials Network 502) trial indicated that if individuals mounted certain va...

HIV vaccine development.

For the past two decades, scientists have aggressively pursued the development of a vaccine against human immunodeficiency virus (HIV). The magnitude of this effort is unprecedented in the history of infectious diseases. However, difficulties in finding promising candidate vaccines have limited the number of clinical efficacy trials. The macaque model is well suited for the evaluation of potent...

HIV pathogenesis and vaccine development.

New information on the crystal structures of the HIV and the simian immunodeficiency virus (SIV) envelopes represented one of the scientific highlights of the 12th Annual Conference on Retroviruses and Opportunistic Infections. Numerous presentations also underscored the increasing recognition of the central role of gut-associated lymphoid tissue in AIDS pathogenesis and helped reveal a better ...

Progress in HIV vaccine development.

Recent advances in HIV vaccine development include initiation of the first efficacy trials and substantial expansion of the preclinical pipeline. Several preclinical candidate vaccines have induced strong cellular immune responses and provided impressive protection against AIDS in non-human primate models; however, candidates that induce broadly neutralizing antibodies remain elusive.
