"Covid vaccination booster"

I received an email and a text message last Thursday, telling me I could book my Covid jab booster.  I booked on-line, being able to choose an easy appointment which I could access before work today.  I arrived to a good welcome in the Leisure Centre car park, then someone with hand sanitiser, and arrived in a well-marked, and well-organised hall.  My vaccination took place within five minutes of the appointed time, and after my waiting for the requisite fifteen minutes, I was able to set off for work on time, leaving the car park with a cheery wave from the volunteer on duty.
