There's a small, but still sizable group of people who are choosing not to vaccinate their children. Here in LA, there are schools in which 20% of the students aren't vaccinated, because parents here are more scared of gluten than they are of smallpox! And, as a result, we now have measles again.
I know if you're one of these anti-vaccine people you probably aren't going to take medical advice from talk show hosts — I don't expect you to, I wouldn't either — but I would expect you to take medical advice from almost every doctor in the world. See, the thing about doctors is they didn't learn about the human body from their friend's Facebook page. 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 little shots. You know these little shots of Botox? Which is Botulinum toxin, by the way? You get in your face to make your head look smooth and your eyes look crazy? A little shot, like that, and "poof!" — polio is gone.
But some people did not buy into that, because they did a bible search, and bullshit popped up. so they listened to what it had to say, and decided not to vaccinate their kids. And by the way, this would all be OK if your kids were the only ones affected — they're your kids. But they're not, because unvaccinated kids put all children in danger, especially babies who are too young to get the vaccination shot... But of course, that's according to doctors, so — you know, take that with a grain of salt.
