"Decades ago, children received only a small fraction of the vaccines required today," Trump said on Monday. "In those times, people were much healthier and of course the high rates of autism now observed did not exist."

The president suggested that the MMR vaccine could be "quite lethal" if given at once. He compared it to pouring a bottle of soda into a child's body.

Every time I think my opinion of Trump can't possibly get any worse, he finds a way to plumb new depths.
