Eastern Europe falling:
Central Europe peaking:
Western and Northern Europe rising still:
Impact of restrictions of lack thereof seem restricted, but mortality rates are a good fit to vaccination rates. How Omicron is going to interact with these is anyone's guess. Since Delta and Omicron immunity don't quite overlap both can coexist to an extent. That could mean there could still be a lot of Delta mortality going on under a huge layer of milder Omicron infections. But rollout of boosters and the natural waning of the Delta wave in the upcoming weeks should make it less likely... maybe.
