According to this study, an anti-retroviral pill--Truvada, a combination of two drugs, tenofovir and emtricitabine--helps prevent AIDS. The study, nicknamed iPrEx, included nearly 2,500 men in six countries and was co-ordinated by the Gladstone Institutes of the University of California, San Francisco. The results are better than the results made public in the summer of 2010 that a vaginal microbicide had protected 39% of all the women testing it and 54% of those who had used it faithfully.
