Two major advances in HIV prevention made Science magazine's top 10 achievements of 2010.
Included in Science's list was a study that demonstrated a microbicide can effectively reduce HIV transmission in women. The majority of the study, conducted in South Africa, was funded by the U.S. President's Emergency Plan for AIDS Relief. In the 889 women who took part in the trial, microbicides reduced HIV transmissions by 39%.
Also honored among the top 10 science achievements of the year was the Pre-Exposure Prophylaxis Initiative (PREP), which demonstrated daily use of the drug Truvada significantly lowered HIV transmission in men who have sex with men. Read more about the PREP findings here.
