I saw Robert Kennedy Jr. (I think) on the Daily Show claiming that Vaccines once contained an ingredient which caused a large number of children to be born with autism. I was under the impression that this claim had been debunked. Has it, in fact been debunked or is it still a valid theory?
If it has been debunked I’m a little angry with Jon Stewart for letting misinformation get through on his show. If not, not. I turn to the dope for answers.
