Two Studies Find Daily Pill Can Prevent HIV Infection

Photo Courtesy - ABC News Radio(NEW YORK) -- AIDS drugs can help prevent heterosexuals from acquiring HIV, according to two studies released Wednesday.

Researchers at University of Washington International Clinical Research Center and dubbed Partners PrEP, have found a daily dose of antiretroviral drugs reduce the risk of HIV infection among heterosexuals by at least 62 percent.

The study, funded by the Bill & Melinda Gates Foundation examined 4,758 couples in Kenya and Uganda in which one partner had HIV while the other didn't.

Although the study wasn't due for release until 2012, the findings were found to be so strong, that the trial was stopped early.

Another study, conducted in Botswana by the Centers for Disease Control and Prevention found that participants taking a daily dose of Truvada instead of placebo were 63% less likely to become infected by HIV.

“These are exciting results for global HIV prevention. We now have findings from two studies showing that PrEP can work for heterosexuals, the population hardest hit by HIV worldwide,” said Kevin Fenton, M.D., director of CDC’s National Center for HIV/AIDS, Viral Hepatitis, STD, and TB Prevention. “Taken together, these studies provide strong evidence of the power of this prevention strategy.”
