There is another good one. Bayer took HIV infected blood from US and Europe and sold it in Africa, infecting many people with HIV in the process.

Also, many medications have under reported side effects. I myself have experienced insane side effects from an antibiotic. Doctors I have seen fail to report to the FDA and claim it is something else. I have talked to many people with the same symptoms and again they encountered the same issue with the medical community. While the FDA actually has been adding more and more serious side effects to the medications label, due to people self-reporting because doctors fail to do so.
