Trump doesn't fact check

In the most recent Republican debate, Donald Trump claimed that he believes vaccines can cause autism in children. The only thing is, decades of scientific research and evidence have came up with nothing. There aren't any true, credible studies that show the linkage between vaccines and autism. Ben Carson and Rand Paul, both physicians, argued that the science linking the two is lacking, but that maybe spreading out the childhood vaccination schedule would be helpful. Due to parent requests, however, many doctors are forced to administer the vaccines to children, which puts them at risk of exposure to disease pre-vaccination. The Times reports that a recent outbreak of measles was aided by people who didn't receive the vaccine and were able to help spread the disease.
