My Dad is 86, got his first AZ jab on something like 27th March, second one on 24th April.
Absolutely ZERO side-effects whatsoever. He remarked to me that the worst part of the whole thing was the boring 15 minutes he was required to wait before he walked back home.
Having my first AZ on Monday, was booked somewhere else for Sunday but got the run around (I haven't been to a Doctor for about 6 years) as they wanted a 'health summary' from a previous doctor - I rang a place I had one followup visit to 6 years ago after a small and pretty insignificant op and they said I was still on the system and to come in on Monday.
Meanwhile, elsewhere in my city there are mass vaccination hubs and I'd bet that everyone in the queue is NOT clutching a 'health summary'.
