Group 6 was estimated to be 7.3 million people and with last week's UHCs it may be something like 9 million.
I think it was suggested that the additional element to be added into Gp 6 was estimated to be 825k, as the rest were already in higher groups so already vaccinated.
I have been trying to see if the number in Group 6 has been shared authoritatively, but without much success.
If anyone has a decent link, please share.
Best I could do is this paper: '
UK prevalence of underlying conditions which increase the risk of severe COVID-19'

8M has separately been suggested, but I think that a proportion of that 8M (includes unpaid carers) have already been included in earlier cohorts. My calculation suggests 4M in (JCVI 30 Dec) Gp 6* and add 825k (as above).
*32M is a widely shared figure for the total of Gps 1-9 (but add 825k (as above)).
14M in Gps 1-4.
11M in Gps 7-9 (aged 50-64) ONS stats give 13M but maybe 2M of those ages will have been vaccinated in higher groups because of morbidity (Gps 4 and 6), NHS and other heath and care workers.
Leaves 7M Gps 5-6.
3M in Gp 5 (65-69) - 3.4M (less maybe 400k in Gp 4).
