Calling 147 is probably a good plan, you'll need patience (especially Mondays), and you can time it a few days after a plane with AZ vaccine arrives. You might get a link to select your vaccination centre, or they might assign you one on the phone.Excellent information about how the system works when the time comes. Thanks.
At the moment Boti de la Ciudad is cheerfully referring to me by name and telling me that he will soon invite me for my second dose. I am at day 71 of 84, but given that AZ seems a bit scarce at the moment and that people younger than me, vaccinated after me, already seem to have received their second AZ, I have that sinking feeling that comes from suspecting one has (again) fallen through the cracks.
On Monday I will ring up, and maybe start dropping in at the vaccination centers.
I guess I'm at day 100 of 84 but only because I missed an appointment. A longer interval between doses seems to be better anyway.
