There is no law requiring vaccinations. Perhaps there should be, but you really can't shame people for exercising their right to control what goes into their body, no matter how dickish it may be. And you REALLY can't shame them for their parents being idiots.

Sure you can shame people for exercising the right to control what goes into their body. It is just as much your freedom to criticize them as it is their freedom to not vaccinate. Just because something is not illegal doesn’t mean you can’t shame it. (I agree that you can’t shame people for decisions their parents made.)

There may be no laws, but at least in Ontario, Canada no up-to-date vaccination means no enrollment to the school/kindergarten.

Not true.

Any parent decline for religious reasons.

You most certainly can shame them, and as long as they get the vaccinations they can, even the ones unlikely to be effective, they've done enough in my eyes to be let in areas I can control attendance to.

And missing one vaccine because their parents are idiots isn't the point. Its the walking infection vectors who are the people who have absolutely no vaccines in them in are the issues.
