Bayer Corporation, the Germany-based pharmaceutical giant, is known for their health care products and veterinary drugs. However, they did a major fiasco back in the 1980s with one of their haemophilia blood products.
According to Wikipedia, Bayer’s Cutter Biological division sold a haemophilia blood product to US citizens, which was infected with AIDS. The drug caused the infection to spread among 10,000 people before Bayer found out their product was contaminated with hepatitis C and HIV. The corporation immediately pulled their product off the US market and started producing a newer version of it. However, in some countries in Asia and Latin America people weren’t convinced the new product would be better than the previous one, so Cutter continued to sell the old drug. According to Bayer, some of the countries were slow in approving the new drug’s sale.
It’s not clear if that was the actual truth or just a creative way to throw dust into authorities’ eyes, but it’s a fact that the corporation made a fortune by selling the contaminated product.
