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.
