There is something strange going on in Scandinavia because UK has reported nothing special with two orders of magnitude more people vaccinated. But it's definitely a cause for concern, at the very least.
There are 441,498 staff working in care homes alone and nearly 90% of these were vaccinated in the first phase.
I don't want to start conspiracy theories but I wouldn't be surprised if it came to light that, in the UK, reports about deaths and side-effects have been suppressed. In the wake of a disastrous Brexit, the UK is in desperate need of a success story and with the Astrazeneca/Oxford vaccine seen as the British contender, it might have become a question of national pride to have it succeed. British newspapers (well, tabloids) present the UK vaccination rate as a vindictive competition with the EU.
If we (I'm British) were accomplished enough to reputation-manage for the vaccine response, I'd have expected the initial (huge) death toll to have been under-reported too - which it clearly hasn't.
