Study Arms:
- Current standard of care (Type: ACTIVE_COMPARATOR): Standard of care therapy may include anti-SARS-CoV-2 specific medication such as, but not limited to:~* Casirivimab~* Casirivimab / Imdevimab (REGN-COV2 or Ronapreve)~* Imdevimab~* Sotrovimab (Xevudy)~* Tixagevimab / Cilgavimab (Evusheld)~* Molnupiravir (MK-4482)~* Nirmatrevlir / Ritonavir (Paxlovid)~* Remdesivir~Centres should ensure that medications used as standard of care are used similarly for patients in both treatment arms.
- Current standard of care and convalescent plasma (Type: EXPERIMENTAL): Current standard of care and the infusion of two plasma units collected from two different COVID-19 convalescent patients.

Based on this trial design, predict the completion outcome and termination type (if applicable).
