We had text messages earlier this week from NHS inviting us to go to a nearby walk-in Covid vaccination centre. Since our GP's had invited us to attend their Flu clinic, but had said that we might also be able to get the Covid jab at the same time "if stocks last", we thought we'd play safe and get the Covid jab straight away. The centre also serves the nearby city, so it was pretty busy, both with those who had an actual timed appointment and those who, like us, had just walked in. There were separate queues and also a queue for disabled people, but the whole system was very efficient and we spent about half an hour waiting, so not bad at all. Our flu jab appointment isn't till October 1st, so plenty of time between the two.
Neither of us had any reaction to the jab. The doctor/nurse who gave it was so efficient that we didn't even feel the "sharp scratch" of the needle going in.
