I had my booster vaccine this afternoon. It was Moderna (I had AZ as my first two) and I had to wait 15 mins before leaving. (Which feels like a long time when you're sat there.
)
I was very impressed with how well run the whole thing was and it was much busier than I'd been expecting! There was me thinking there'd be one nurse giving boosters every 10 mins or so, but there were at least four working simultaneously. They, along with all the check-in staff, were very efficient and friendly. The NHS is great.
