Up to 30,000 people contracted HIV and hepatitis C in the 1970s and 80s after being given blood treatments or transfusions on the NHS.
Thousands have since died.
It just goes to show there is no such thing as a sure thing.
The WTS may be wrong about their blood doctrine, and their bible interpretation to justify it, and how they enforced the rules about it, but ultimately may be correct in claiming that "bloodless surgery" was a safer option medically.
Canada also had a contaminated blood scandal, where 30,000 were infected with Hepatitis C and HIV.
In other news, paying for blood from high-risk donors is a bad idea. Who knew? Well apparently the people behind the schemes did, and that's why they covered it up.
