Links vaccines to autism epidemic during CNN debate

During the CNN Republican debate, Trump falsely claimed that autism has become an "epidemic" largely due to vaccines, describing a scenario where a "beautiful child" gets a "horse" sized dose and becomes autistic. He advocated for smaller doses over longer periods, spreading debunked medical misinformation on a national stage despite Ben Carson (a neurosurgeon) gently correcting him.

"Autism has become an epidemic... you take this little beautiful baby, and you pump—I mean, it looks just like it is meant for a horse... and two years later... a child has a tremendous fever, gets very, very sick, now is autistic." — CNN Republican Debate, September 16, 2015
