Update this morning - the National Booking service now includes in it's eligibility criteria:
Who can use this service
You can only use this service if any of the following apply:
you are aged 60 or over
you are at high risk from coronavirus (clinically extremely vulnerable)
you are an eligible frontline health or social care worker
you have a condition that puts you at higher risk (clinically vulnerable)
you are a main carer for someone at high risk from coronavirus
I tried to book online but it still wouldn't allow me, so I tried calling 119 and whilst I was on hold, I had a text from my GP inviting me to book, so I'm booked for next Weds! So very happy.
I think it's worth Group 6 trying again, either online or maybe via 119 as it's looks like we're now included in the National Booking service.
