UK had strict age-banded rollout, starting with the eldest. By the end of this study, I had just had my first dose (I'm 27, and I booked it as soon as possible). It's not at all surprising that older populations were more likely to die.

Depends on the demographics of who gets vaccinated and who doesn't. If the elderly get vaccinated at a higher rate, it seems normal that vaccinated people would have a higher non-covid mortality rate.

It is also not surprising if healthy people are less likely to get vaccinated.

Wouldn’t the original study depend on demographics as well? If the young get vaccinated at a higher rate, it seems normal that unvaccinated people would have a higher covid mortality rate.

Well, if you think about who got vaccinated first, it should be pretty obvious why that is the case, don't you think?

Aye. Stratification required here.

I don’t see any mortality data for vaccinated vs. unvaccinated in your link?
