gollark: If UK health authorities had actually called for stopping COVID-19 vaccine use, then yes, this would be worrying.
gollark: Because it became a political issue currently.
gollark: That still doesn't fix the data apparently being bad and open-submission.
gollark: And you shouldn't just go for the worst-case scenario (conveniently one making your preferred point best) when assuming things; you should find the most realistic one, and/or provide a range.
gollark: The US government has frequently been useless and incompetent at pandemic handling (halting the J&J vaccine and initially claiming masks didn't work are the two obvious things I can think of), but that doesn't mean that everything they say is wrong, or that belief in things that the government says is necessarily just because the government says it.
