I sympathize, but the problem with this is that you'd inevitably end up punishing the child, who is then more likely to grow up feeling like he was victimized by "the system" rather than his parents. This is a hostage situation unfortunately. Anti-vax parents are holding their kids hostage, and we as a society are on the hook for the consequences when the hostage gets hurt. There's no good way around it.
