You may be familiar with Penn and Teller for the magic tricks and comedy, but between 2003 and 2010, the pair also had their own TV show on the cable network Showtime, which basically aimed to debunk pseudoscientific ideas, conspiracy theories, and paranormal beliefs, among other topics like political issues. In one episode, they take on the pseudoscience that is anti-vaccination.

We won’t get into the things they say in the video above, but, despite what anti-vaxxers will say, the benefits of getting vaccinated far outweigh the risks — that point cannot be stressed enough. Case in point: the measles outbreak currently sweeping through the West Coast. As of Monday, an outbreak of the preventable disease spread from a handful of people who visited San Diego’s Disneyland to at least 85 people in seven different states and Mexico, CBS News reported. Its spread has attributed to children who haven’t been vaccinated — Orange County has a high prevalence of vaccine exemptions.

California is currently experiencing its worst measles outbreak in 15 years, according to the Los Angeles Times. In 2010, it experienced a severe outbreak of whooping cough that hospitalized 9,000 people and killed 10 infants — the majority of people affected were children under 3 months old. Yet many parents remain unconvinced, hardheaded from hours of misleading research. The fact of the matter is that while some kids might experience adverse effects from the vaccines, not getting one puts them at risk of not only more harm but worse outcomes.
