PrEP is a drug that experts believe could end the HIV and AIDS epidemic. On the 70th anniversary of the NHS, this is the incredible story of the battle for PrEP to be made available on the NHS - a legal fight which saw doctors, activists and AIDS charities come together to overturn an NHS decision.
At the heart of the story is one man, Greg Owen, who, despite being homeless, helped stop thousands becoming HIV positive by setting up a website which allowed people to buy generic PrEP from drug manufacturers in India.
