Experimental: SARS-CoV-2 convalescent plasma
SARS-CoV-2 convalescent plasma (1 cup; minimum of 175 mL collected by apheresis from a volunteer who recovered from COVID-19 disease and has SARS-CoV-2 antibody titers ≥ 1:320 and after July 2021 meets FDA criteria for high titer plasma.

Other Name: Human coronavirus immune plasma (HCIP) |
Active Comparator: Standard Control plasma
Plasma collected from a volunteer donor prior to January 1, 2020 will not be tested for SARS-CoV-2 antibodies. Plasma collected after December 31, 2019 will be confirmed as SARS-CoV-2 seronegative.

- Cumulative Number of Hospitalizations or Deaths Prior to Hospitalization [ Time Frame: Up to day 28 ]Cumulative Number measured as the proportion of subjects who were hospitalized or who died prior to hospitalization
- Cumulative Incidence of Severe Infusion Reactions [ Time Frame: Up to day 28 ]Cumulative incidence measured as rate per person-years experiencing treatment-related severe infusion reactions during the study period.
- Cumulative Incidence of Treatment-related Grade 3 or Higher Adverse Events [ Time Frame: Up to day 90 ]Cumulative incidence measured as rate per person-years experiencing a Grade 3 or higher.
- Cumulative Incidence of Treatment-related Acute Respiratory Distress Syndrome (ARDS) [ Time Frame: Up to day 28 ]Cumulative incidence measured as rate per person-years of treatment-related severe Acute Respiratory Distress Syndrome (ARDS) during the study period.
- Serum SARS-CoV-2 Antibody Titers by Visit [ Time Frame: Days 0, 14, 28 and 90 ]Geometric mean Spike Receptor Binding Domain (RBD) titers at day 0, 14, 28 and 90 between the randomized arms.
- Number of Participants With ICU Admission [ Time Frame: Up to day 90 ]Disease severity measured by admission to the ICU
- Number of Participants With Invasive Mechanical Ventilation [ Time Frame: Up to day 90 ]Disease severity measured by invasive mechanical ventilation
- Number of Participants Who Died [ Time Frame: Up to day 90 ]Disease severity measured by death
- Number of Participants With Resolved COVID-19 Symptoms at Day 14 [ Time Frame: Day 14 ]Number of participants with resolved COVID-19 symptoms at day 14
- Number of Participants With Resolved COVID-19 Symptoms at Day 28 [ Time Frame: Day 28 ]Number of participants with resolved COVID-19 symptoms at day 28
- Number of Participants With Resolved COVID-19 Symptoms at Day 90 [ Time Frame: Day 90 ]Number of participants with resolved COVID-19 symptoms at day 90
- Impact of Convalescent Plasma on Outcome as Assessed by Change in Hospitalization Rate [ Time Frame: Day 0 to Day 90 ]Assess change in hospitalization rate as measured by number of hospitalizations stratified by age groups <65 and >=65
- Impact of Donor Antibody Titers on Hospitalization Rate of Convalescent Plasma Recipients [ Time Frame: Day 0 to Day28 ]Impact of donor antibody titers (high/low) will be assessed by hospitalization rate as measured by number of hospitalizations.
