I booked on the website and an hour later got a text from my GP offering me a vaccine . Presumably that just means that where i live is running at the national average speed for vaccine progression.
I didn't realise that you might still not get one if you are in a postcode where they are lagging. I thought that this was a way of giving everyone of 50+ the opportunity to book at a national centre even if their particular GP practice was still a bit behind.
Sorry to those who can't get an appointment yet.
