Today the PROUD study interim analysis finds pre-exposure prophylaxis (PrEP) is highly protective against HIV for gay men and other men who have sex with men in the UK.

Yusef Azad, director of policy and campaigns at NAT (National AIDS Trust), said: "The announcement that the PROUD study has already shown such a significant benefit in preventing HIV transmission is exciting and welcome news. HIV transmission in the UK remains far too high, especially amongst gay men, and we need to add to the prevention options available. These encouraging results provide powerful evidence that PrEP should be accessible to all who need it as soon as possible."
