Agreed, it's far too much for most parents. The professional conditions, motivations and rewards around childhood disease vaccine development profoundly differ vs the 60s-80s. As a family we do research for a living and now find our own parental burden too high, whereas pharma's aggression for schedule expansion has become cavalier and most doctors lack basic education and authority. So the default position, even for those with the time and tools, is naturally to drop the castle gate and say "wait!" Which infuriates the Pushers and turns them into Punishers. As trusting parents get their kids taken for a pharma ride, these abuses are going to harden memories for the next 100 years and longer.
