> nothing you said negates the main point that reinfection is creating worse outcomes in some people

Except for the parts where I point out that this result is confounded by the advanced age and morbidity of the study population; the health-seeking behavior that led to their inclusion; and the fact that they're all getting older across the course of the study (which tends to result in higher rates of death, illness and relocation to Florida. I wonder if he found that Covid caused higher rates of golfer's elbow?)

Also, no, the study didn't show anything is "creating" anything else. It argued that there's a correlation.
