"comparing romania to france is not meaningful at any given time"

I do not disagree with this statement, but it should also be stated that comparing the unvaccinated to the vaccinated is not meaningful anymore either. The characteristics of the two populations has diverged spectacularly in most countries. In my country, the method seems to be: vaccinate those who have a high probability of already having natural immunity, charge for testing and mandate the unvaccinated test 1-3 times a week in order to survive, tell the vaccinated they do not need a test if they are sick (just stay home), do not vaccinate the most likely to die such as cancer patients, and whatever you do, do NOT adjust VE for any confounding variables.
