Appeal court rules NHS does have power to commission prep HIV service

NHS England has lost its appeal over a High Court ruling that it has the legal power to commission PrEP, a "game changer" service in the fight against HIV/Aids.

PrEP, short for "pre-exposure prophylaxis", is a prevention strategy which involves people who are HIV negative but at high risk of infection taking the anti-retroviral drug Truvada to reach optimal levels of protection.
