Willful ignorance, illiteracy, and poor government education in way of public service TV spots, etc. I think if children die or are permanently disable because their parents were criminally negligent in not getting them vaccinated, should stand trial for murder in the first case, or be sentence to lengthy prison terms for the latter.
Oh, what the hell is a daycare center doing accepting children whose parents didn't supply proof of vaccination before they were ever admitted? Ever taken your dog to a kennel? They demand as much there.
Well, damn, I guess there is something we totally agree on, after all. When a child dies of a disease that has a common vaccine, just because the parent does not 'believe' in vaccines, that parent should stand trial for negligent homocide. If that child carries measles, or some other contagious disease into an area, like a hospital with new borns, and that cause damage to the babies there, the parents of that child should face charges as you reccomended. We both saw the results of the polio epidemic in 1952 and the wonderous termination of that dread childhood disease by the '70's. How can anyone say the vaccines are more dangerous than the diseases after that example?
