We've talked about anti-vaxxers a lot on the show. Especially since we had Rob Schneider hang up on us when Buzz asked if he was one. Seriously, wouldn't answer the question, just hung up.

For some reason people still think that not vaccinating your kids is a good idea. Kristen O'Meara was that way. She chose not to vaccinate her young daughters because she believed the "research" that claims vaccinations lead to autism.

"It was awful, and it didn't have to happen, because I could have had them vaccinated. I felt guilty. I felt really guilty," she told ABC News.

It has been stressed for years that kids need to be vaccinated by the Center for Disease Control and Prevention, the World Health Organization, and many, many other public health groups.

"I'm here because I wanted to share my personal story ... and if it does help someone change their mind, then that's great," O'Meara said.
