Factor VIII was billed as a medical miracle when it was put on the market in the late 1960s: a revolutionary treatment for people with haemophilia. But as the treatment was rolled out, haemophiliacs began to contract hepatitis and AIDS in terrifying numbers. Even as medical bodies and pharmaceutical companies tried to discredit whistleblowers and diminish the evidence, it became abundantly clear that the ‘miracle’ treatment was infected. And the government embarked on a cover-up on an industrial scale. Cara McGoogan follows the survivors-turned-campaigners, the small-town lawyers and the fearless journalists, to uncover what really happened in the infected blood scandal.
