This new wave may well be the biggest test yet as to whether the UK establishments 'live with Covid by doing almost fuck all different to normal times' can be gotten away with.
Because this time we dont have a well timed booster campaign for anywhere near as many people. We may well not have a variant that is milder in terms of not targeting the lungs. We dont have much in the way of rules left, or much free testing, or a public 'keen to save Christmas' or a government keen to ask people to do the right thing, or a media that will loudly and constantly reinforce such messages. And hospital infection control measures have progressively been reduced in various ways.
So the most obvious thing we do have left is a reliance on the overarching theme of 'the population is different now to what it was at the start, because there is now a complex immunity and protection picture, a situation where the virus (or at least the spike of the virus via vaccines) isnt brand new to everyones bodies'. Plus some proportion of the most vulnerable already died from it.
And those sorts of fundamentals are broadly what makes a pandemic a pandemic in the first place, and where the main action and justification is for the 'we can go back to normal' people. There are potential flaws and limitations to that sort of simplistic approach though, and not just from attempting to pretend we've reached that point too soon. eg even when the virus lacks the potential to kill at such high rates, it can still place quite the burden on healthcare, a burden that was not there before this virus arrived, a burden that can upset another kind of numbers game in an ongoing way.
But I am oversimplifying somewhat, the central 'population immunity picture is different' likely can carry quite a lot of real weight, and we still arent 100% reliant on it to cope with this wave and future wave. Some older people got a well timed booster again, more treatments are available, some people are still being cautious. School holidays arent here yet but are looming and usually help. And if the situation gets real bad then behaviours will change in response again, the media will pay more attention, etc etc. But if those things are required then a mockery will still be made of various relaxed attitudes and the governments 'the pandemic is over, we can live with the virus without special effort' shit.
We've been here before with me probably making similar points, but the amount of good fortune with these new Omicron versions sounds like it will be less than what we enjoyed with the first few Omicron versions, and so I consider this to be a fresh test. And there is some evidence that all the Omicron infections that happened already havent made a wonderful difference to the population immunity picture, may not have really got us any closer to the promised land.
