Isaac Asimov was a victim of tainted blood.

So was a good friend of mine in high school - he had hemophilia.

In 1977, Asimov suffered a heart attack. In December 1983, he had triple bypass surgery at NYU Medical Center, during which he contracted HIV from a blood transfusion.[94] When his HIV status was understood, his physicians warned that if he publicized it, the anti-AIDS prejudice would likely extend to his family members.
