The United Nations programme working to combat HIV/AIDS welcomed yesterday the results of a number of recent clinical studies of the effects of antiretroviral medicines on preventing new HIV infections, which were presented at a conference on viruses held in Seattle.
At the 2015 Conference on Retroviruses and Opportunistic Infections (CROI), the results of two separate studies on pre-exposure prophylaxis (PrEP) medicines showed 86 per cent efficacy in preventing new HIV infections among men who have sex with men.
A third study showed that in so-called serodiscordant couples – where one partner has HIV and the other does not – access to PrEP for the HIV-negative person combined with access to antiretroviral therapy for the HIV-positive person was 96 per cent effective in preventing new infections.
"These new results are a significant breakthrough in advancing efforts to provide effective HIV prevention options to men who have sex with men and to serodiscordant couples," said Michel Sidibé, Executive Director of UNAIDS. "The results are timely and important and will advance global efforts to end the AIDS epidemic by 2030."
