Just to add to our collection of anecData. I've had two AZ Jabs 12 weeks apart. As far as I am aware, I've not had Covid.
First one 4pm, felt OK going to bed that evening, but soon developed fever, aches and mild delirium through the night with little sleep. Completely wiped out the following day with aches and fever and bed bound. Moderate tenderness around my jabbed arm. Second day was still very wiped out but could get out of bed. Took about 6 days to get back to normal.
Second jab two days ago also at 4pm. Recognised a similar but milder 'heady' feeling by early evening. Took precautionary paracetamol and slept through the night. Next day a little tired but started OK. But by 11am aches and fatigue started again and retired to spend most of day in bed. Similar tenderness around jab site. Next day, still a little tired and 'heady', but far less severe, probably about the same as 'day 3' after first jab.
So overall, similar significant reactions to both jabs, but second one not quite as bad as first.
