Tony Fauci looks back at the scientific breakthroughs that have transformed HIV/Aids from a death sentence to a disease that can now be treated and prevented. Having watched in horror as his patients quickly died from the disease in the US in the early 1980s, as director of the National Institute of Allergy and Infectious Diseases, he has dedicated his career to fighting it.

He talks to the Aids activists who pressurised the US government and Dr Fauci himself to find the drugs they so desperately needed and the scientists whose extraordinary discoveries lie at the heart of the global fight against the disease. And while that fight continues, Dr Fauci believes a recent breakthrough could one day herald an Aids-free generation.
