And this bit:
"vaccinated individuals had a 74% lower risk of death from severe COVID-19 and no increased risk of all-cause mortality"
> These are the important bits for the non medical folks
Also significantly: "vaccinated individuals consistently had a lower risk of death, regardless of the cause."
that in itself could be healthy user bias (if a healthier subset was taking up the vaccine).
did they control for that?
Its a cohort study, so you can only control for confounders. The 2nd paragraph of the discussion addresses the healthy-vaccinee effect you're referring to.
They define unvaccinated as anyone who wasn't vaccinated by Nov 2021. What if they got vaccinated afterwards?
This is specified as an exclusion criteria in the Supplementary.
No they didn't. They excluded those that got the vaccine pre-May 2021 or those that got another vaccine besides Pfizer or Moderna.

What specific impact do you think that would have on this study? Do you think vaccines prior to Nov-2021 were safe and they were unsafe after? Do you think short term results, captured after Nov-2021 are more relevant than inclusive results prior?
