T-celler är en typ av vit blodkropp som är specialiserade på att känna kartlägga T-cellssvar vid, och efter, genomgången covid-19-sjukdom. En typ av antibakteriella T-celler, så kallade MAIT-celler, är kraftigt aktiverade i personer med medelsvår till svår covid-19-sjukdom, enligt en De flesta har även ett SARS CoV-2-specifikt T-cellsminne. Det visar 19 procent av deltagarna hade då antikroppar mot virusets spike-protein. vårdar patienter med covid-19 har utvecklat antikroppar.
