On another forum I saw someone take this to the most offensively stupid level of claiming without modern vaccines humanity would go extinct. Yes, let's just ignore that we somehow survived as a species just find for hundreds of thousands of years prior to the invention of vaccines, humanity requires them to survive at all.
It's the level of overreach that disgusted me. Even in the filthiest of human times we still had an unaided survival rate out of infancy of 50% (and after about 5, it was relatively smooth sailing, even maternal mortality was 10% over their entire reproductive career so closer to 1% risk per birth, not like women died after two pregnancies or we would have again, not been a viable species. If you didn't die very young you were probably going to live into your 60s). They could have made their point by at least acknowledging that. Plus, our medical technology advanced on so many other levels I don't think even if we stopped the childhood vaccination schedule completely it would go back to the Ancient roman or medieval death rates.
The measles vaccine, which seemed to prevent measles just fine in my lived experience, has only been around for 50 years. Measles was a gag in old tv shows by that point, not some frightening plague. Losses to it would be a fluke in modern western society even if they shot got wiped out of existence.
Vaccination was a fine concept when used strategically, we should never have granted the companies immunity since it created too much incentive to bloat up the schedule.
