Most of the Europe is heavily vaccinated (much more than the UK which is by now in the middle of the pack). The biggest difference between the UK and rest of the Europe is that the UK was vaccinating mainly with Astra Zeneca and was 3-4 months ahead of rest of the Europe.

Scandinavians stopped being concerned and they downgraded COVID severity to public health to the level of flu. What do they know?
