100 percent of participants taking HIV prevention pill Truvada remained infection-free.

Truvada is expensive and needs to be taken every day, but it works.
The Centers for Disease Control and Prevention says that PrEP has been shown to reduce the risk of HIV infection by up to 92 percent when taken consistently but is much less effective when taken inconsistently. In one key study, called PROUD that included men who have sex with men in Britain, the risk was reduced by 86 percent.
In this study, 100 percent of the participants remained HIV-free. That's right, not a single person in the study, published in Clinical Infectious Diseases, became infected while on the drug during the study period that included 2.5 years of observation.
"Tremendously good news," University of California-San Francisco researchers Kimberly A. Koester and Robert M. Grant (one of Time's most influential people of 2012 for his work in AIDS) said of the results in a commentary accompanying the publication of the study.
