A few thoughts this morning:
1) Those thinking that climate will buy us respite will probably be wrong...see South Africa. It's the South African summer and it's growing rapidly.
2) The very fact that two mutations apparently developed independently involving the same amino acid sequence suggests that the natural advantage is significant.
3) What is the impact on the herd immunity threshold? The equation is simple but do we know what the new R0 is? And furthermore,this whole topic is weird in respect of Covid as the national epidemics crash at low prevalences which have led many to speculate that herd immunity will be a lot lower - partly because many many people do have some pre-existing immunity.
4 Why does it take so long to confirm whether the vaccines are effective against the variants? We've been tracking the evolution of the virus since day 1 and antigenic drift and vaccine evasion is a well-known phenomenon. Can we assume that Pfizer, Moderna,etc are working on vaccines for the new variants?
5) Assuming that the vaccines are still effective, then we should very quickly devise a plan to counter the growth of the new variants. Even with the Oxford vaccine, t's going to take a couple of months to vaccinate significant numbers and the original priority list does not touch the fast spreaders. If we don't change the vaccine priority we will all be in permanent lockdown for weeks. Blair's suggestion was not bad but there are probably better ways to do this.
6) Great hope rests on the vaccines. Assuming they are effective, there should be a wartime effort to get the first few millions into people. Seriously I would change the priority list relatively early so that teachers and all health-workers are vaccinated. The supply from the Oxford vaccine should allow us to vaccinate the elderly and make some strategic decisions regarding the variants.
The vaccination programme needs to be epic in its scale.
