Our youngest had some form of measles before she could get the MMR vaccine. Wildest part was taking her to the hospital and no one knowing wtf to do. The doctors all basically shrugged and said good luck. She seems fine now 3 years later, but her immune system seems wildly fucked up. Like totally fine to some sicknesses and horrible responses to others.

Edit: I mean this in a, "It's Illegal to say what I want to do to you" way. If you don't get the MMR vaccine when you could've, you are directly responsible for my child's suffering. I want you to feel that suffering.

I've decided people need to learn the hard way

Bold of you to assume people will learn. Didn't you hear about that couple whose kids died from measles and they said afterwards that they still feel their decision to not vaccinate the kid was right.

Except that vaccines partially work because of herd immunity. My kid is and was vaccinated against whooping cough, but enough fucktards here in Texas refuse vaccines that it is spreading and he caught it despite being vaccinated. He was ultimately fine because he was 14 with a good immune system, but pertussis can be fatal for some patients, especially those too young to get vaccinated.

You don't sound like your smart enough to understand this explanation, but at least I tried.
