Between 1970 and the early 1990s more than 30,000 people in the UK were infected with HIV and Hepatitis C through contaminated blood products and transfusions. It has been described as the worst treatment disaster in NHS history. Since then, around 3,000 of those infected have died, but many of their relatives have yet to receive any compensation. A public inquiry opened in 2018 to discover what really happened, and in May it will deliver its final report. Reporter Jim Reed meets the families of some of the 380 children with bleeding disorders who were infected with HIV and talks to them about what they have lost, their campaign for justice, and what they hope for from the inquiry.
