With the help of nonhuman primates (NHP), French researchers may be close to answering the nearly 40-year old riddle that is AIDS.
On July 6, AFP reported that scientists had successfully tested the vaccine dubbed HVTN705 or "Imbokodo" in monkeys, shielding them from infection and triggering an immune response. It now moves to the next phase where it will be tested in 2,600 women in southern Africa. The results from the trial are expected in 2021 or 2022.
While we must be cautiously optimistic that Imbokodo will be successful in humans, this represents a great leap forward, thanks to the assistance of NHP models. A Harvard Medical School professor notes in the article that in the nearly 40-year history of AIDS, this is just the fifth vaccine concept to make it to the efficacy stage in people.
