An unexpected but welcome development at AIDS 2026 was the reappearance of post-exposure prophylaxis (PEP) for HIV as a subject for scientific study and funding.
The two most basic features of PEP have remained and are enshrined in the World Health Organization’s guidelines, which are followed by most countries. Firstly, PEP should be taken ideally within 24 hours and certainly no more than 72 hours after an exposure. Secondly, it should consist of a four-week course. This was thought necessary for situations where PEP was started late and HIV may have gained a foothold inside cells.
