Just last week a new study showed that a daily pill that is already stocked in pharmacies could prevent new HIV infections in gay men. The drug, Truvada, is already being used to treat HIV, but a three-year study found that a daily dose cut the risk of infection in gay and bisexual men when given with condoms, and other prevention services. The study found the drug lowered the chance of infection by 44 percent and up to 73 percent when the drug was taken faithfully.
