U.S. Researchers Infected Guatemalan Prisoners With Syphilis

United States researchers infected 1,300 Guatemalan prison inmates with venereal disease for an experiment to test penicillin in the 1940s. The NIH-funded project “did not treat participants as human beings, failing to even inform them they were taking part in research, as was the case for a similar study in the United States,” a presidential commission announced on Monday.
