Carolina children conferred significantly greater & more enduring protection against covid-19 hospitalization than full mRNA (BNT162b) covid-19 vaccination–Data from 887.2K children in the months when omicron was predominant

I made the following figure from the raw data provided in the supplement which disingenuously recorded follow-up on different scales: weeks (out to 20) for the vaccine follow-up; months (out to 10) for prior infection. Nevertheless, at 10-months prior infection/naturally acquired SARS-CoV-2 immunity conferred 86.9% protection against hospitalization which exceeded the 2-month protection (85.9%) afforded by vaccination, with the gap widening each successive month (i.e., months 1-5) where direct comparisons were available!
