Sanjay Gupta interviews Bill Gates at CNN:
Gupta: There has been a lot of scrutiny of vaccines recently — specifically childhood vaccines. There has been a lot of news about is there a connection with autism, for example. What do you make of all that? Dr. [Andrew] Wakefield wrote a paper about this [in The Lancet in 1998] saying he thought there was a connection. And there were lower vaccination rates over a period of time as a result in Britain, then the United States. What are your thoughts?
Gates: Well, Dr. Wakefield has been shown to have used absolutely fraudulent data. He had a financial interest in some lawsuits, he created a fake paper, the journal allowed it to run. All the other studies were done, showed no connection whatsoever again and again and again. So it's an absolute lie that has killed thousands of kids. Because the mothers who heard that lie, many of them didn't have their kids take either pertussis or measles vaccine, and their children are dead today. And so the people who go and engage in those anti-vaccine efforts — you know, they, they kill children. It's a very sad thing, because these vaccines are important.
