A division of the pharmaceutical company Bayer sold millions of dollars of blood-clotting medicine for hemophiliacs -- medicine that carried a high risk of transmitting AIDS -- to Asia and Latin America in the mid-1980's while selling a new, safer product in the West. 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. Yet for over a year, the company continued to sell the old medicine overseas. Cutter officials were trying to avoid being stuck with large stores of a product. Yet even after it began selling the new product, the company kept making the old medicine for several months more. In Hong Kong and Taiwan alone, more than 100 hemophiliacs got H.I.V. after using Cutter's old medicine. Many have since died. Cutter also continued to sell the older product after February 1984 in Malaysia, Singapore, Indonesia, Japan and Argentina. While admitting no wrongdoing, Bayer and three other companies that made the concentrate have paid hemophiliacs about $600 million to settle more than 15 years of lawsuits accusing them of making a dangerous product. Federal regulators helped keep the overseas sales out of the public eye. The Food and Drug Administration's regulator of blood products, Dr. Harry M. Meyer Jr....asked that the issue be quietly solved without alerting the Congress, the medical community and the public."
