Experimental groupEXPERIMENTALSubjects randomized to convalescent anti-SARS-CoV-2 MBT plasma plus SMT will receive one infusion of 200 to 300 ml of ABO-compatible convalescent plasma obtained from a convalescent donor.
Control GroupPLACEBO_COMPARATORSubjects randomized to placebo plus SMT will receive one infusion of 200 to 300 ml of sterile saline solution 0.9%.
Convalescent anti-SARS-CoV-2 MBT Plasma + SMTEXPERIMENTALParticipants will receive 2 consecutive transfusions of 200 to 250 milliliters (ml) of ABO-compatible convalescent plasma with each unit of plasma, obtained from the same convalescent donor, which will be administered on Day 1 using standard procedures for administration of fresh frozen plasma. Participants weighing less than 45 kilograms (kg) will receive two transfusions of 10 ml of convalescent plasma per kilogram of body weight with each unit of plasma obtained from the same convalescent donor. Participants will also receive all standard of care interventions while hospitalized, from Day 1 to Day 29.
Standard Medical TreatmentACTIVE_COMPARATORParticipants will receive all standard of care interventions required throughout the participant's hospitalization, from Day 1 to Day 29.
