The Kefauver-Harris Amendments were inspired by which tragedy?

• A. Thalidomide tragedy in Europe
• B. Sulfanilamide tragedy
• C. Tylenol cyanide crisis
• D. E. coli outbreak

Answer: (A)

Regulatory safeguards for drug safety and efficacy were expanded after a birth-defects tragedy linked to a sedative given to pregnant women. The thalidomide tragedy in Europe, where thousands of babies were born with severe birth defects, spurred the U.S. to tighten controls. The Kefauver-Harris Amendments of 1962 require that new drugs prove both safety and effectiveness before they can be approved, mandate rigorous clinical testing with informed consent, introduce stricter manufacturing standards, and enhance reporting of adverse drug reactions. This event directly led to those enhanced protections, making thalidomide the driving catalyst behind the amendments. The other events listed prompted different safety responses in pharmaceuticals, but the Kefauver-Harris changes are most closely tied to the thalidomide tragedy.
