Talk show host Jimmy Kimmel revealed a bitingly funny “public service announcement” on Friday that has since been seen by over 2.4 million people.

The video, which can be seen on YouTube, is introduced in its “about” section by the message, “Jimmy feels that all of this anti-vaccination silliness is starting to snowball, so he invited some real doctors to address it. These are actual medical professionals so hear them out and then decide for yourself.”

The video starts out with a monologue by Kimmel, who pokes fun at health fads and internet diagnoses. “See the thing about doctors is they didn’t learn about the human body from their friend’s Facebook page,” he says. “They went to medical school where they studied all sorts of amazing things like how to magically prevent children from contracting horrible diseases by giving them a little shot.” He also fired a salvo saying that parents against vaccination “are more scared of gluten than they are of smallpox.”

Kimmel’s bit is followed by a video featuring seven different doctors who all state, “I believe in vaccinations” and “there is no reason not to vaccinate your kids.” It seems at first a normal service announcement, until one doctor says, “I cannot (expletive) believe we have to make this PSA.”

From there the censure only becomes more deriding. “You people still won’t listen,” says one doctor, followed by another lamenting, “Now I have to use my only day off to talk to you about vaccines?” Another doctor chimes in with the cutting and hilarious remark: “Hey remember that time you got polio? No, you don’t, because your parents got you (expletive) vaccinated!”

A mock voice-over at the end of the video announces that it was “paid for by professionals who know what the hell they’re talking about.”
