For the first time, a vaginal gel has proved capable of blocking the AIDS virus: It cut in half a woman's chances of getting HIV from an infected partner in a study in South Africa. Scientists called it a breakthrough in the long quest for a tool to help women whose partners won't use condoms.
The results need to be confirmed in another study, and that level of protection may not be enough to win approval of the microbicide gel in countries like the United States, researchers say. But they are optimistic it can be improved.
"It's the first time we've ever seen any microbicide give a positive result" that scientists agree is true evidence of protection, said Dr. Anthony Fauci, director of the U.S. National Institute of Allergy and Infectious Diseases.
The gel, spiked with the AIDS drug tenofovir, cut the risk of HIV infection by 50 percent after one year of use and 39 percent after 2 1/2 years, compared to a gel that contained no medicine.
To be licensed in the U.S., a gel or cream to prevent HIV infection may need to be at least 80 percent effective, Fauci said. That might be achieved by adding more tenofovir or getting women to use it more consistently. In the study, women used the gel only 60 percent of the time; those who used it more often had higher rates of protection.
