It’s difficult to judge the eligibility age area by area as they vary so much. Where I live, they are still working through the over 80’s with just a few pockets vaccinating 75 to 80 yr olds yet obviously from what people are saying here, under 75’s are being booked in somewhere else.
There are indeed two systems on the go, deliberately so I am told. One works through regional NHS trusts and use the big centralised hubs. The other is being run by GP practices using local centres, it’s not according to type of vaccine, both are being used by both systems. The idea is that if an admin slip up occurs, you will get a call by one of them, obviously some people get both alerts. At the end of the first four categories
( mid Feb) , there will be announcements that any eligible people who have not had the vaccine can then make contact to book an appointment without a letter, text or phone call.
The powers that be are currently deciding on the next groups to be called, it might not be those of us aged 60 to 70 in the next two categories as they are considering any priority groups, such as key workers.
I know this because my ex husband is working on the computer programmes facilitating the admin of appointments and, although I don’t talk to him, he has told our daughter.
