A study of which STILL doesn't take into account the obvious simple sampling error of if you have COVID, you're documenting and a medical professional is noting all your adverse effects, while if you were vaxxed, you're much, MUCH more likely to NOT be having a medical professional loom over you and noting every adverse reaction. (AND there's politically pressure to not notice the side effects, but we're even going to ignore that bit.)

Or in layman's terms, birds "scientifically" by this study's kind of logic, die more often in the suburbs than in the entire rest of the world combined, because people watch it happen there but don't watch it when no one is there to observe it in the wilderness, so no birdwatcher reports of it happening means it never happens, birds are actually immortal unless a birdwatcher is nearby. That's this study's logic.
