THAT’S NOT A HUGE IMPACT, BUT IT’S NOT NOTHING: Convalescent plasma reduces mortality by 10% in COVID-19 patients on artificial respiratory assistance: Clinical trial. “The effect on reducing mortality was more specifically observed in patients who received convalescent plasma during the first 48 hours after being put on artificial respiratory assistance. . . . This study documents and confirms the value of convalescent plasma for passive immunization against the most severe forms of COVID-19, but also against possible future more pathogenic variants and possibly in the event of future pandemics.” Especially in a patient population that’s so ill.

I donated convalescent plasma several times after having Covid, so I’m happy to hear that it might have helped someone.
