Turning point in COVID-19 severity and fatality during the pandemic: a national cohort study in Qatar by Chemaitelly, Hiam

“…Conclusion The conclusion of the first omicron wave was a turning point in the severity of the pandemic. While vaccination and enhanced case management reduced severity gradually, the rapid accumulation of natural immunity during the first omicron wave appears to have played a critical role in driving this shift in severity.…”
