New studies show 100% HIV protection in monkeys via antibody combos

Two separate research teams showed a unique combinations of antibodies led to 100% protection from HIV-like viruses in test monkeys. They'll next enter human clinical trials, first testing their safety, in the hopes of eventually creating both a vaccine and therapies.

What they did: The two studies published Wednesday — one using a "first of a kind" antibody molecule that can bind to three different places on the HIV virus and the other using a cocktail of two single antibodies — state they believe the antibodies' ability to target different regions of the virus, which can mutate rapidly, prevented infection.

Why it is important: In the U.S., roughly 1.1 million people are living with HIV, and one in seven of them don't know it. The majority of new cases are reported in the South, showing a disparity of infection rates.
