If your child is not vaccinated, they should be barred from attending public school

[Seamus Fermanagh]

Perhaps the "clear and present danger" concept used in limitation of free speech could serve as a benchmark.

Our default -- at least here in the USA under our Constitution -- must be in favor of individual choice.

If you choose to avoid vaccination, government should not be allowed to force you to comply unless it clearly presents a danger to the public at large, but (with the consent of its voters) should be able to impose reasonable limitations for health and safety, public education, food preparation, and the like. The basic concepts of public health codes in restaurants etc. is what is being applied here. If you choose to dine at a private home, or a private "supper club" you take your chances with the health practices of those preparing the food etc. Public licensure is made available to organizations who agree to abide by government standards for sanitary arrangements etc.

Only when someone knowingly continues to threaten public health or well-being should drastic measures be taken on behalf of the polity. Example
