Anti-Vaxxers Turn Disneyland Into Measleland!

They say it’s the happiest place on earth, but it’s recently made a lot of people pretty miserable. An measles outbreak originating at Disneyland in Anaheim, California, in mid-December, has now been traced to at least 22 cases of the infectious disease. Of those infected, 12 were unvaccinated, four were vaccinated, and six didn’t know if they were vaccinated or not.

BUT HEY! If vaccines are so great, then how did four vaccinated people get the measles, huh?

Well, the reason everyone is supposed to be vaccinated is to increase “herd immunity.” Vaccines don’t work for everyone and in every case, and often wear off as one gets older — but if every child is vaccinated than it’s far, far more unlikely that those for whom the vaccine doesn’t work will contract the disease.

Parents who don’t vaccinate their kids also, ironically, rely on herd immunity in the hopes that because everyone else is vaccinated, their kids won’t be subjected to these viruses. However, with more and more parents choosing not to vaccinate their children, herd immunity is decreasing, and we are seeing outbreaks of old-timey diseases like the measles and whooping cough.

But hey! As long as your kid doesn’t get imaginary autism, amirite?
