Everybody is different so I don't think it's possible to generalise at all.
My other half was absolutely shattered on the day after her AZ jab, not too bad on the following day and fine the day after. 2nd jab no problem of any sort.
My first jab was fine, I only knew which arm it was because I watched him do it, 2nd jab mildly sore arm for a day or two.
We know somebody else who spent the whole of the day after the first jab being sick, but nothing after 2nd jab.
My sister munched ibuprofen for a few days after the first jab because her arm was so painful, 2nd jab nothing. Brother in law nothing after first jab, 2nd jab a headache for nearly a week.
I can't see a pattern...
