When I got my first, and then my second, I didn't knock on anything. I just ignored the cassandras and was fine. Those with serious reactions are low.
My wife and her coworkers got their second jabs back in January from the Moderna batch that was known to have higher than usual reactions amongst many who got it. Although anecdotally there seems to be less reports of bad reactions to the Pfizer vaccine (my mother reported no issues after her second dose), I take nothing for granted.
Upper arm near the shoulder is predictably a little sore at the end of this second day, but nothing that affects range of motion or limits usage of that arm in any way. Hopefully the aftermath of the second jab is rather uneventful as well.
