Looking at the UK data pg 18-19, >= 50 group, Received 2 doses vs. Unvaccinated appears to show a very strong protection against death. I calculate the case fatality rate as 1.638% for vaccinated against 5.605% unvaccinated. The under 50 age group is basically a wash on case fatality rate; perhaps a very slight benefit to vaccination. Do you agree with that observation?

If those are your calculations then I believe you. Yes - in places, depending on whether we are talking about a variant and which, you can find a reasonable difference in the older ages CFR, where the vaccinated group's is lower.

While it is not automatically a correct inference to conclude that is /caused/ by the vaccine, because it could also be a byproduct of who you vaccinated and other differences, I hope it is because the vaccines are giving additional benefits to those groups.
