this afternoon it all seemed to change with jabs going into everybody in the [Bolton] queue.
Prevalence in Bolton is twice that of the second worst!
You can see the marginal benefit (see SPI-M-O precis in my post above) of using doses in specific areas of high prevalence (with a more transmissible variant) as first doses for all adults accepting the opportunity cost of slightly slower (by a few days) second doses in areas (regions even) of the UK where prevalence is very low. There's clear merit in turning round vaccine hesitancy in those areas/communities too and getting first jab uptake into the high 90s. Look at the number in Bolton hospital who had been offered a vaccine and refused it (some may have for medical reasons, of course).
Send the relevant hubs some diverted supplies (at the expense of other regions whose second doses can stay at 11-12 weeks and who can pause the first jabs for 37+ year olds) and allow the local vaccine programme managers some freedom to achieve clear objectives (see below).
Surge vaccination (high prevalence areas) priorities:
1)
First jabs for the previously vaccine hesitant (with the almost explicit threat of a local reversion to greater restrictions as the 'stick')
2)
Second jabs for all those over 55 (will be an 8 week gap at least) - note the enhancement of a second jab at 8 weeks is less than one after a gap at 12 weeks (but the next 4 weeks matter in high prevalence areas)
3)
First jabs for anyone over 18
Vaccinating the third category is not in line with the direct saving of lives/from serious illness (the JCVI mantra) but, 14 days down the line, all adults will have first jab level of protection; thus the susceptible population will have shrunk and community spread of this highly transmissible virus variant will be curtailed. Indirectly this will save lives and importantly keep cases UK-wide lower than they would be if we (just) plough on down the ages. This is a better outcome for the UK population as a whole and for the vast majority in particular. This hopefully temporary diversion of effort is, I acknowledge, not without operational challenge.
I wonder if there is a SAGE/SPI-M-O versus JCVI battle going on? Politicians will be the arbiters, thank goodness: we've seen how these scientists love to argue (arguing is a good thing btw, though not so much when the enemy is firing at you).
