We've had one Chrstmas in lockdown, yeah it was a bit shit, but not as shit as Spring 2020 which was to be fair utter tripe. 2019 Christmas was pre covid and therefore fab and 2021 Christmas is tracking along to be normal again thank goodness. 🎉
40 die a day, WITH not of covid i.e. of any cause, within 28 days of a positive test. This is only 0.1% of tested infections. The vaccinations are working.
Too many died in the UK, who did not need to die. The intial response was woefully inept and lacking in imagination (i.e. the imagination to anticipate what was coming down the line, apply a "value" to information coming from the then centre of the pandemic and act accordingly). Not stopping the flights early on, and making claims that this would be somehow racist or xenophobic is unforgivable and probably the biggest failure of the UK government, next to discharging covid positive patients into care home settings and leaving people at home until they were "blue", gaslighting them that they couldn't have covid as there wasn't much of it in the UK ...even though almost no one could access a test even when dreadfully ill, so we actually had no idea how much covid was circulating. 
One wonders if the government thought they could simply negotiate and bluster their way out of a viral pandemic as if it were Brexit negotiations. 
The vaccination development and administration programme however has turned out to be a masterstroke, so swings and roundabouts.
