(Forego still means precede, even though so many incorrectly use it when meaning forgo.)
I gladly advocate forgoing vaccinations for endemic and childhood diseases, because the vaccines are so effective. They reduce culling, and long term cause harm to humanity by saving individual children.
New harmful or detrimental mutations in the human genome that in themselves are not enough to kill someone, but in combination with diseases like measles have a statistically significant higher morbidity are allowed to spread undiluted into our gene pool. These saved children have children of their own, where they otherwise would have died. When some ignorant anti-vaxxer says that vaccines cause autism, they may very well be right, but for the wrong reasons. It's not the vaccine itself, but that children who might have died now live to reproduce. If children with autism have any lower survival rate if they catch measles than children without autism do, no matter how small that difference is, by vaccinating against measles, the prevalence of autism will increase. There's a significant correlation between vaccinations against childhood illlnesses and the next generation being sicker from other illnesses like autism, asthma and spectrum disorders.
And we get superbugs. Through vaccination against endemic diseases, we instigate an arms race, where new and worse strains appear, which we have little protection against, unlike the milder versions that outcompeted any bad ones because we didn't wage war on them.
