During the CNN GOP debate in September 2015, moderator Jake Tapper asked Dr. Ben Carson if he believes that vaccines can cause autism. He does not. When the question was asked of Donald Trump, however, he responded:
"I am totally in favor of vaccines. But I want smaller doses over a longer period of time. Same exact amount, but you take this little beautiful baby, and you pump--I mean, it looks just like it's meant for a horse, not for a child, and we've had so many instances, people that work for me. ... [in which] a child, a beautiful child went to have the vaccine, and came back and a week later had a tremendous fever, got very, very sick, now is autistic."
