R could possibly rise to 2.3, variant could emerge in schools amongst the unvaccinated population
This must be modelling a huge decrease in vaccine protection, as there are no more restrictions to drop to increase R, and little behavioural change based on the movement etc. studies.
If that is the case, then surely the main concern should be that, not any worries about "new variants.
I expect the reality is that "could" is about the same could as aliens visiting or Boris becoming competent.
