Document 2018 DOCN M94A2018 TI The dilemma of developing a vaccine against HIV. DT 9412 AU Bolognesi DP; Duke University Medical Center, Durham, NC. SO Int Conf AIDS. 1994 Aug 7-12;10(1):4 (abstract no. PS4). Unique Identifier : AIDSLINE ICA10/94370557 AB Despite an unprecedented research and development effort that has been ongoing since the mid 1980's the quest for a vaccine against HIV has and continues to experience a pattern of unsteady progress. Animal model studies have not produced uniform guiding principles but rather a complex and often confusing picture. Frustrated, vaccine developers have turned to man as the experimental model but here too unanticipated obstacles have stymied progress. With over a dozen vaccine candidates in clinical trials including two in Phase II studies and an infrastructure being prepared to accept vaccines for large scale efficacy trials, the HIV vaccine field is at a crossroads, with forward movement difficult in the absence of clear correlates of immunity. At the same time several new developments stemming from studies of HIV pathogenesis may help point the way toward a better understanding of correlates of protection and with several promising vaccine strategies under development, the outlook for eventual success remains plausible. These and other issues related to HIV vaccines will be discussed.
