This is an excellen twitter thread with lots of data, but if you're looking for the TLDR, here is the summary from the end of the twitter thread:

- UK’s July reopening likely generated enough infection-acquired immunity to shield it from continent’s winter wave

- But that came at a cost of thousands of deaths, far higher rate than peer countries [so far]

- Boosters also key to UK’s current successes

- If western European countries can accelerate booster rollout they can blunt the wave, esp in terms of hospitalisations & deaths

- But some, like Austria, are hamstrung by low uptake of the primary course. You can’t boosted the unvaxxed, and Austria has a lot of them.
