Reactions to Covid vaccinations and asymptomatic Covid

Has anybody felt poorly following the Covid vaccinations, yet gone on to develop asymptomatic Covid?

If anyone asks me whether I've had Covid, I've always said no, reasoning that a bad reaction to the vaccinations meant that I'd know about it if I caught Covid.

My husband, however, had no reactions to his vaccinations and has symptomatic Covid. It's made me have a re-think. Can anybody back me up or disprove my thinking?
