Got the 'vid at a big convention, with Chinese visitors, in early February of 2020, long before there was any tests, vaccine or even any awareness of the threat. The symptoms, in retrospect, were very clearly 'vid. Lasted 3 months, but I was fine.
Got it again a year later when that second round hit... just a day or two of illness, and about 10 hours of elevated temperature... and at that point I still wasn't eligible for the vaccine because I was too healthy, not old enough and didn't smoke.
Later, when the vaccine came out I asked my doc and she said "Why? You've had this twice - at this point your natural antibodies are far better than any shot could offer!" So... I didn't get vaxxed, and neither did the wife because, naturally, she'd also got the 'vid those same times when I did, and she similarly survived just fine.
Over Christmas this past year my son, who is a medical professional in an emergency room, brought home the latest variant when he spent the holidays with us. He is vaxxed, but got sick as a dog for about a week. Wife and I had light symptoms for about a day and that was it.
