Side effects update for Cherie as she kept asking:
My wife had;
Immediately after vaccine - sore, stiff arm at vaccination site (found changing gears on the drive home hard, etc)
Rest of that day - had to go for a nap/"feeling the cold" into the evening
Day 2: a little tired/nauseous but not enough to stay off work or anything so very minor.
Day 3+: totally fine.
So reports all good thus far

. A coworker of hers however (who is in her mid 50's, dunno if that's relevant) had a temperature and felt very sick and had to take two days off, but fine after that. This is also second hand info so it's possible her coworker just fancied some time off and was sat with Netflix and popcorn [emoji23].
