I guess the concern many of us have is that it was too rushed, (and we do understand why it was rushed), and that the total implications/side effects have not yet been fully realized.
We've had three shots each and won't get more.......with identical symptoms I was diagnosed as having flu, while she had covid, (as was a friend at the same time); they both 'recovered' (actually 'felt better' is probably more accurate), before I did, although mine was nothing to e-mail home about, (writing, of course, being somewhat passé now).
