Pill protects against HIV in real-world settings

By Andrew M. Seaman (Reuters Health) – A once-a-day pill for preventing infection with the human immunodeficiency virus (HIV), the virus that causes AIDS, has been effective in clinical trials, and new research suggests that it works in the real world, too. In a study conducted at sexual health clinics, participants taking the pills for so-called preexposure prophylaxis, or PrEP, had only two new HIV infections, although their rates of other sexually transmitted infections and condomless sex remained high, researchers found. “There were a number of clinical trials that looked at PrEP and showed it to be safe and effective in that research setting, but there was little information on how PrEP would be implemented outside of those research trials,” said lead author Dr. Albert Liu, of the San Francisco Department of Public Health.
