So this study only looks at covid-19 patients that were hospitalized and comparing that to the vaccinated population? How is it an improvement to introduce a selection bias that wasn’t there in a previous study? I guess more data points are always good but then the conclusion they reach here about natural immunity vs vaccinations needs to be qualified.
