I already got four shots.

This isn't necessarily relevant. Different vaccines require different numbers of doses to reach full effectiveness, including periodic boosters in some cases. I've had way more than 4 flu shots in my life, but I still get one if I get around to it each year. I recently had another tetanus booster, which is #5 or 6 (there are several scattered among the infant/toddler immunization schedule, then I've had one every 10ish years since). I probably won't get another hep B shot, though, since the 3 I got are the full course (as far as I know). It varies from shot to shot, and for something as new as Covid in particular, I expect it to be several years before we settle on a "best" approach.
