Factor VIII
During the 1970s and 1980s, the boys' school offered specialist care for haemophiliacs. With the introduction of Factor VIII treatment, between 1974 and 1987 many were injected with Factor VIII imported from the United States and manufactured from contaminated non-heat-treated blood plasma, and were infected with HIV and hepatitis; 90 out of 122 have since died. A public inquiry into the National Health Service's use of contaminated blood products began taking evidence from those affected in 2019, and in 2021 heard statements from former Treloar's pupils who were infected there.
