After three doses of Pfizer my 4th was Moderna. Incredibly well organised volunteers in the indoor tennis courts of a hotel. Actual centre felt cavernous and empty but the long and well spaced line outside suggested it was doing great "business." What was especially reassuring was the actual jabber's explanations. Yes, I was getting a different vaccination and yes it would be entered on my NHS records within the week. I didn't need to explain anything, it was all covered.
Difference for me was that I was in and out in less than 10 minutes. I was told to sit in my car for 15 minutes in case of a reaction. None so far, although my arm is beginning to ache just a little.
Fully jabbed now and not looking forward to contacting 119 tomorrow to piteously ask the question "Where is my letter about priority PCR test and urgent treatment process if I come into contact with the virus?"
