I think that carehome residents and staff are fine at the top. They tend to have elderly and/or highly vulnerable residents, there have been some nasty outbreaks, and they are very much suffering from a mental health and well being hit from the increased isolation. Theynare a readily identifiable group of people, couid probably be done quite quickly, and then residents couid be visited more readily (even if some precautions stayed in place)
I'd do NHS staff, the exceptionally vulnerable and the extremely old next. Plus those with planned admissions to hospital 2 weeks before date.
Then other elderly, prisons (staff and inmates), social workers and emergency services.
Then over 65s and those who routinely receive a free flu jab
Then other vulnerable and over 60s
Then over 50s, and essentially keep going down the age ladder after that.
The spanners in the works will be
a) whether the first vaccine/s available will,be suitable for the elderly and some categories of exceptionally vulnerable
b) how many shots are needed for a full course
c) whether boosters are needed and at what interval
