Hopefully, but I'm not sure I share your confidence. These are irrational actors, and irrationality is difficult to model. It's also difficult to reason your way out of a position you did not reason into. There's definitely numerous documented cases where children are very much suffering and the parents will not give them emergency treatment. I'd go so far as to say in that irrational world, not vaccinating your kids may be a necessity and not a luxury. I very much hope I am wrong, but I don't think these parents will change their position regardless of the facts, and the only short-term solution may be external intervention. Again, I will be very glad if proven incorrect.
