Contaminated haemophilia blood products
Contaminated haemophilia blood products were a serious public health problem in the late 1970s through 1985. These products caused large numbers of haemophiliacs to become infected with HIV and hepatitis C. The companies involved included Alpha Therapeutic Corporation, Institut Mérieux (which then became Rhone-Poulenc Rorer Inc., and is now part of Sanofi), Bayer Corporation and its Cutter Biological division, Baxter International and its Hyland Pharmaceutical division. Estimates range from 6,000 to 10,000 haemophiliacs in the United States becoming infected with HIV.
