I'm my experience, in California/USA there was strong political denial of anything possibly negative about the vaccines.
Public health authorities were proclaiming that there were no possible side effects, even as other countries were restricting demographics and discontinuing use.
If we're talking about the Astrazeneca vaccine in particular in this subthread, with its clotting side effects-- it's worth noting that it never received a US EUA. It's not surprising that US agencies never restricted its use, having never authorized its use in the first place.
(With the bulk of issues being non fatal)
"hundreds of thousands" didn't die though, in all of Australia there was just one person that "probably maybe" died due to TTS (IIRC).
It was first spotted in the European adverse side affect database and written about early on.
