You've made at least 2-3 personal attacks against me while seemingly not even trying to address the problem that I highlighted. If that's your goal, OK. It definitely goes against the spirit of the rules here if not the letter.

Delaying the flu vaccine? Ok that's bad, sure.

It's also a real goalpost move and also doesn't address the technical problem "insiders going to inside" I raised in answer to the parent's paraphrased "I can't understand this, why is this necessary?"

I don't know that doing things this way is strictly necessary. But I also don't think it's reasonable to just hand-wave away or worse completely fail to even acknowledge much less actually address the insiders problem.
