It's kinda sad, really.

When 1poormom was a girl, there were very few vaccines. She knew people who were crippled by polio, and died of other diseases you never really hear about today. When she had kids, and vaccines were available, she made sure we had them all.

Now the generation that is raising primary school aged kids has no memory of those diseases, and believe all the conspiracy theories and pseudoscience nonsense about vaccines, and aren't getting their kids inoculated. When their children start getting sick (already happening) and dying (not yet, but it's likely coming), it will be a tragedy of their own making. They will have failed to learn from history.

We, as a species, seem to have to relearn everything for ourselves. As kids we didn't listen to our parents when they warned us about stuff (because they had already "been there", but we thought they were out of touch). As adults, we pay no heed to history, and then are surprised when we repeat the old patterns and get the same results that history told us we would get. Don't get the MMR and Tdap and polio vaccines? Expect your kids to suffer, and sometimes die, because of those diseases.
