There are reports that the new variant boosters will be ready for September and that they will be given to over 70s. Do you think this will continue to the lower priority groups later on in the autumn/winter? There is some talk that it might only be needed for vulnerable groups. I don't know if this is because the modelling suggests that only vaccinating the top 4 groups will be enough to stop the NHS being overwhelmed, or whether they think that lower groups will have enough immunity from the current 2 boosters, or whether it is just a practical time/cost decision.
(this is assuming that all adults are done by the end of July).
Presumably if they start on children at the same time, they might get the newer version, which could help slow transmission of the new variants, although I suppose it depends exactly what's been tested, and whether new trials are needed (for adults, they say that full trials won't be needed for new boosters).
