"It needs to be determined whether such protection against severe disease at reinfection lasts for a longer period, analogous to the immunity that develops against other seasonal “common-cold” coronaviruses,4 which elicit short-term immunity against mild reinfection but longer-term immunity against more severe illness with reinfection. If this were the case with SARS-CoV-2, the virus (or at least the variants studied to date) could adopt a more benign pattern of infection when it becomes endemic." You gotta do better than this, the source your cite doesn't support your point at all.. this study completely excludes vaccinated people and you are using it to say "infection is much more protective than vaccination". What are you doing here?
