Leave it to Jimmy Kimmel to have a hilarious way to let his views on vaccination be known.

It’s a pretty a clear opinion: get your children vaccinated. But since Kimmel doesn’t expect parents will take advise from a talk show host, he brought on a bunch of real doctors to say what they think. No joke, they are actual medical professionals.

And since there’s a small part of the population that are anti-vaccination, they got rather angry about his message. So, the next night he gave them some airtime too.
