Vaccination appointments

[Willow4987]

Does anyone know roughly how regularly vaccination centres release batches of appointments?

I’m trying to book the local one which offers AstraZeneca and moderna which DH has an appointment at next week. But I can’t see any centres available within a 50 mile radius

I looked for my DD and there were none available locally. Two days later there were. I'd try every day.

Every couple of hours new ones were popping up in my area.
