Everyone is different. I've always had one, due to my lung problems.
However, as I'm now 65, I got a different vaccine from usual.
I react to everything, lots of allergies, comorbidities, compromised immune system, etc, etc.
I always feel unwell, just varying degrees, so nothing different there. I wasn't in the least bit surprised at the effects this time!
However, I would rather have the innoculation and suffer, as opposed to the consequences. It's a matter of individual choice. It's not worth stressing over.
I have to admit, I did complain a bit about feeling rubbish!?
