The contaminated blood scandal, also known as the infected blood scandal, is a British medical scandal in which a large number of people were infected with hepatitis C and HIV, as a result of receiving contaminated blood or contaminated clotting factor products. Many of the products were imported from the US, and distributed to patients by the National Health Service throughout the 1970s and 1980s. Most recipients had haemophilia or had received a blood transfusion following childbirth or surgery. It has been estimated that more than 30,000 patients received contaminated blood, resulting in the deaths of at least 3,000 people. In July 2017, Prime Minister Theresa May announced an independent public inquiry into the scandal, for which she was widely praised as successive governments going back to the 1980s had refused such an inquiry. May stated that "the victims and their families who have suffered so much pain and hardship deserve answers as to how this could possibly have happened." The final report was published in seven volumes on 20 May 2024, concluding that the scandal could have been largely avoided, patients were knowingly exposed to "unacceptable risks", and that doctors, the government and NHS tried to cover-up what happened by "hiding the truth".
