We often tend to think that medical and drug testing only happens here in the United States using vulnerable populations, such as the 600 impoverished black males who were told they would receive free health care from 1932-1972 in the well-known Tuskegee University syphilis studies. The studies were unethical and caused death and more disease. But Big Pharma, in this case Pfizer, continues the same unethical biomedical research methods even today, especially in poor African countries.
