In 1960, Richardson-Merrell applied for approval for a drug called Thalidomide, a cancer treatment. They had clinical trials that included pregnant women. They were rejected six times.
In the UK, The Distillers Company (Biochemicals) Ltd, a subsidiary of Distillers Co. Ltd marketed thalidomide as Distaval, a remedy for morning sickness. Their advertisement claimed that "Distaval can be given with complete safety to pregnant women and nursing mothers without adverse effect on mother or child ... Outstandingly safe Distaval has been prescribed for nearly three years in this country."
By 1962, over 10,000 children (most in west germany) were born with crippling disabilities caused by thalidomide. Over 2,000 died.
Frances Oldham Kelsey was awarded the medal for Distinguished Federal Civilian Service by President John F. Kennedy for rejecting the drug.
