Otoh I do think the lagging behind will be a short lived problem. The big increase in vaccinations today is in line with the new centres opening post weekend and all my elderly contacts (mostly 70-80) are in the queue over the next week. That said my in-laws in the Home Counties, both in their mid-70s, were vaccinated over a week ago.
I understand the notes of caution but I do have to ask what is the point of vaccinating everyone if it doesn't lead to opening up? Fingers crossed serious symptomatic transmission and hospitalisations do indeed drop by 80% once the vaccine kicks in for the over 70s (per JVT et al iirc).
