The problem, at least speaking as a US citizen, is that children cannot be vaccinated and are subject to testing requirements if they become ill. Also, even the vaccinated are having breakthrough cases and if not, are afraid of them or are being required to get tested again.
I see this exempts children but makes the mistake of tying specific vaccination decisions to the public health benefit of having free testing. It's abusing a public health tool as a cudgel, a pattern I'm seeing in various places.
If this happened in the US, it would just lead to undocumented spreading and delays in care, worsening outcomes.
Im worried with things like this, and similar missteps by the US government, we're heading back to March 2020.
