It spells the end of 'vaccinate and open up' as a tenable policy.
But if enough people get a third jab now, we'll make it through the next ten weeks with minimal restrictions, which takes us to March, fingers crossed that 'starting to wane' actually means that for most people it's a fair few weeks longer and we get through to the natural summer lull.
Then it can all be ignored, as the chances of this shower of shite actually planning for next variant or the next winter virus season seem remote (I'm sure there will be diligent experts doing the work, but it's not going to percolate up to decision makers!
Big area of remaining uncertainty is how many hospital admissions will happen in the coming days, and it's now a week or so since the start of the really big spikes in positive tests. And whether that will be enough to cause disruption (widespread sickleave/isolation and/or need for further restrictions)
Delta
2% admitted with 40,000 cases = 800 admissions
Omicron (if it causes 70% fewer admissions)
0.6% admitted with 120,000 cases (where we are now) 720 admissions
0.6% admitted with 150,000 cases (small increase) 900 admissions
0.6% admitted with 180,000 cases (moderate increase) 1080 admissions
Omicron (if it causes 60% fewer admissions)
0.8% admitted with 120,000 cases 960 admissions
0.8% admitted with 150,000 cases 1200 admissions
0.8% admitted with 180,000 cases 1440 admissions
There's a lot riding on very small 'headline' differences
I don't know at how many admissions the NHS starts buckling
