The thalidomide tragedy resurrected Kefauver's bill to enhance drug regulation that had stalled in Congress, and the Kefauver-Harris Amendment became law on 10 October 1962. Manufacturers henceforth had to prove to FDA that their drugs were effective as well as safe before they could go on the US market. The FDA received authority to regulate advertising of prescription drugs and to establish good manufacturing practices. The law required that all drugs introduced between 1938 and 1962 had to be effective. An FDA - National Academy of Sciences collaborative study showed that nearly 40 percent of these products were not effective. A similarly comprehensive study of over-the-counter products began ten years later.

Answer this question, if possible (if impossible, reply "unanswerable"): What did this new law prohibit?

Tragedin med talidomid återuppväckte Kefauvers lagförslag för att förbättra narkotikaregleringen som hade stannat upp i kongressen, och Kefauver-Harristillägget blev lag den 10 oktober 1962. Tillverkarna var hädanefter tvungna att bevisa för FDA att deras läkemedel var effektiva och säkra innan de kunde gå på den amerikanska marknaden. FDA fick befogenhet att reglera reklam för receptbelagda läkemedel och att etablera god tillverkningssed. Lagen krävde att alla droger som infördes mellan 1938 och 1962 måste vara effektiva. En undersökning som genomfördes av FDA - National Academy of Sciences visade att nästan 40 procent av dessa produkter inte var effektiva. En liknande omfattande studie av produkter över disk inleddes tio år senare. Svara på denna fråga, om möjligt (om möjligt svara "osvarbart"): Vad förbjöd denna nya lag?
