Convalescent Plasma Therapy for the Treatment of COVID-19: A Review of Clinical Effectiveness

  • Convalescent plasma (CP) therapy is an intervention where plasma is collected from patients who recovered from COVID-19 in the hope that the disease-specific antibodies could help the recipient recover from COVID-19.
  • Evidence on the effectiveness of CP therapy for the treatment of COVID-19 is still in the early stages.
  • This report summarizes the current evidence and it will be updated monthly as a living review.

  • Since the Addendum to the April 20, 2020 Brief Overview was published on May 29, 2020, The Lancet retracted an article that had significant impact on the conduct of clinical trials of hydroxychloroquine in the treatment of COVID-19.
