I believe that the age groups are now being done by the bigger vaccination centres, but group 6 is being done by GP's ie two different sites.
I know my GP surgery has been delayed to a whole bunch of people now being added to group 4 as well, so have to do those people first before getting to group 6.
I know a friend of mine in group 7 (next county over) has his booked already for this week at a bigger centre (he's got quite a trek to get there)
