In another study entitled ‘Early Transfusion of Convalescent Plasma in Elderly COVID-19 Patients to Prevent Disease Progression’ (clinical trial no. NCT04374526), the investigators hypothesize that the transfusion of CP, comprising the neutralizing antibodies, at an early stage of COVID-19 infection can prevent the inflammatory response induced by SARS-CoV-2. This evidence concerns the gene CP and COVID-19.
