The amount of people with multiple boosters etc. that have gotten COVID I know is also insane. The efficacy cannot be anywhere near what was claimed, or has deteriorated since for sure. I'm not just misunderstand statistics, there's just _too many_ people I know like that for that to be the case.
As an anecdotal data point though: I got COVID once a year ago and have been perfectly fine otherwise. No long term condition, nothing. Just 3 days of flu like symptoms, but worse. Without the vaccine.
