I think vaccinating kids is questionable even if they are potential transmitters. The protection has to be achieved in another way.
Because opening and closing the economy definitely isn't the right way to do it either.
The problem with the (any, for that matter) pandemic is, that we only have limited capabilities in the health service. If we all get sick at the same time, the system collapses and there will be drama and tragedy to an extend most of us can't comprehend. And it's simply the main goal to prevent that from happening. We have a vaccine which is clearly the best solution we have right now. So we should aim to vax as much people as we can. The remaining question is, how do we do this? Is a forced mandate this the best way to achieve this goal? I mean, we have a vaccine for about a year (?) now and everyone who's willing to get vaxxed has got the shot. How will those remaining 30% react?
Stick that in your right wing pipe of ignorance and smoke it.
