I don't share the pessimistic view that cases will spiral and hospitals become overwhelmed again because of COVID. It was always expected that cases would rise going into the winter, and this was basis of the logic of getting the cases out of the way in the summer. Hospitalisations are what matters, and while they're going up these are still well down on previous peaks and not in the realm that the NHS in England might be overwhelmed. This is according to Westminster spokespeople, and I agree with them, for now anyway.
It is disappointing that vaccine immunity seems to be waning faster than hoped, and this seems to be the cause of the current increases (and poor performance relative to other countries who weren't so quick off the mark), but boosters should deal with this problem. Fairer criticism might be that the booster programme could be quicker, but even this seems to be going at a decent pace and there is already evidence of cases dropping in the older age groups relative to the rest of the population. The 12-15 year old roll out seems to be slow in England, but this matters little in terms of preventing hospitalisations as children are unlikely to be seriously affected anyway. Plus, one of the major problems seems to be that large numbers of children can't get it because they have COVID, so they will have gained a decent chunk of natural immunity instead, which might well turn out to be more robust long term.
I hate this rhetoric that unless you're wearing masks/restricting venues/doing whatever your favourite restriction is, that you're letting rip and doing nothing though. (Not necessarily here, but there's plenty of it about.) Everyone who wants a vaccine has now had the opportunity to get one, boosters are being offered to the vulnerable now that it's clear that the vaccine wears off relatively quickly (AZ especially), and I don't see any other reasonable end point in terms of allowing people to live their lives. I really think that everyone is eventually going to get it so protect the vulnerable as much as you can (which we are, with vaccination) and let people move on.
