Studies show success in HIV drugs for preventionThe practice, known as pre-exposure prophylaxis, or PrEP, means that a healthy person who engages in sex with an HIV-positive partner takes anti-retroviral drugs daily as a preventive measure to ward off HIV. "Pre-exposure prophylaxis (PrEP) is a game changer" in preventing the spread of HIV, said US researcher Chris Beyrer, co-chair of the International AIDS Society (IAS) science conference in this western Canadian city. The research showed that when PrEP is used correctly, it reduces HIV infection and is well-tolerated.
