Presidential aspirant Michele Bachmann has a reputation for being gaffe-prone, but her latest comments so incensed University of Pennsylvania bioethicist Arthur Caplan that he has challenged her to put her money where her mouth is.
Bachmann told Fox News and the Today Show earlier this week that she had heard from a distraught mother whose daughter "suffered mental retardation" as a result of receiving the Gardasil cervical cancer vaccine.
Caplan used Twitter and email to announce that he would donate $10,000 to the charity of Bachmann's choice "if she can produce a case in one week... verified by three medical experts that she and I pick of a woman who became 'retarded' (her words) due to the vaccine."
