"The Bayer unit, Cutter Biological, introduced its safer medicine in late February 1984 as evidence mounted that the earlier version was infecting hemophiliacs with H.I.V"
"The documents ? internal memorandums, minutes of company marketing meetings and telexes to foreign distributors ? reveal and chronicle Cutter's decision to keep exporting the older product after it began making the new one, which was heat-treated to kill H.I.V. The heat treatment rendered the virus "undetectable" in the product, according to a government study.
Man.. wtf??
