Picked Other because there needs to be a system in place to separate parents who can't (or really shouldn't) vaccinate their children because the kid is immunocompromised, has an allergy to a component in the vaccine, or other valid health reasons from the parents who don't vaccinate their children because "b-b-but it causes autism!"

If it's the latter, the parents should be getting a call from CPS.
It should be implied that children that can't be vaccinated are not vaccinated.
That much is obvious, but the question asks what should happen to parents of children who are not vaccinated, which would imply punishment for parents of children who can't be vaccinated.
I'm not very good at this...
