A recruitment ad for the clinical trial that found an injectable long-acting drug could protect certain groups from HIV infection.

It’s not an AIDS vaccine but it may be the closest thing to one so far. A long-acting antiretroviral drug given as an injection every two months powerfully protected uninfected people from HIV in a large-scale study that was disrupted by the COVID-19 pandemic. The apparent success—the study has not been published in a peer-reviewed journal or presented to HIV researchers at a meeting—offers a potentially easier alternative to taking daily pills of other antiretrovirals, which has proven difficult for many people.
