The global fight against the human immunodeficiency virus is poised to make important advances thanks to three experimental HIV vaccines that are entering the final stages of testing at sites across the globe.
While any of these three late-stage HIV vaccine trials — known as HVTN 702, Imbokodo and Mosaico — could fail, scientists say they are more hopeful than at any time since 1984, when Secretary of Health and Human Services Margaret Heckler raised hopes by predicting that there would be a test-worthy HIV vaccine within two years.
Dr. Anthony Fauci, director of NIAID and a longtime advocate for a vaccine that is at least 50 percent effective, said he feels “even more strongly now” that a partially effective vaccine would be worth deploying. He said that is because prevention strategies like pre-exposure prophylaxis (PrEP) and treatment as prevention (TasP) “are being so successfully used, even in the absence of a vaccine, that if one or more of these vaccines look good, have a 50-60 percent efficacy, I think that’s going to be the game changer for turning the epidemic around.”
