US: Zero gay men contract HIV in two and a half year PrEP study

Researchers at the Kaiser Pemanente Medical Centre in San Francisco have given over 600 people Truvada to use daily across a two and a half year period – with not one person contracting HIV. 

Lead researcher Jonathan Volk said these results represent a unique opportunity to truly understand the usage of Truvada and PrEP in a real-world setting. “It suggests the treatment may prevent new HIV infections even in a high-risk setting,” he said. Volk was referring to the fact that many of the men in the study claiming to have highly active sex lives – often sleeping with multiple partners in a short space of time.

“Until now, evidence supporting the efficacy of PrEP to prevent HIV infection had come from clinical trials and a demonstration project,” he added. However, while none of the participants contracted HIV, 30% did contract an STI within the first six months of the study. This number increased to 50% after one year.  Read More via PinkNews
