More anecdotal "evidence:"
A friend and teammate of mine, Chuckles, now lives in retirement in Brooksville, FLA. He didn't get vaccinated, got C19 on July 4th and was in bed for three weeks. Yesterday, when I spoke to him a month after infection, he still hasn't resumed his normal low impact workouts. Glad he is recovering---one of the nicest guys in the world. He is more than a bit of a flake, so I am curious about why no vax, but will follow up when appropriate.
His next door neighbor was not so fortunate. She didn't get vaxxed and died. Contributory factor may have been the 100 lbs more than Chuckles she weighed. Her last words to Chuckles were for him to take care of her pet pig, Pork Chop. However, a month later, Pork Chop got a disease, which was untreatable. Excavator dug a hole, Pork Chop was led into it and got AR-15'd.
