alt Hacker NewsThe tweet immediately before this one says:
> There's a weird disconnect in this vaccine mandate debate: many are still pretending that Covid-19 is of natural origin, which gives such mandates a different feel than they otherwise have.
Contrary to your assertion, this is not clearly talking about vaccine mandates in any particular place. And the tweet I quoted previously is claiming (or hinting) that the same "state entity" had caused the pandemic and mandated the "experimental treatment". I'm not familiar with any versions of the lab-leak hypothesis that claimed that covid escaped from a US lab, so I don't think it's a reasonable inference that he's talking about the US vaccine mandate.
On the other hand, he seems to have worked pretty hard to avoid clearly stating any of his positions here, so who knows what he really thinks? Or thought?
The problem with your scenario is that the Chinese government didn't have a covid vaccine mandate in October of '21 (when Blow's tweet was published).
Their covid vaccine program was voluntary up until they tried to establish a mandate in July of '22 (a lot of commentators seem to be confused on this point, as there are mandates for childhood vaccines in China - but these never extended to covid vaccines)
