The Coronavirus Disease 2019 (COVID-19) pandemic has presented a global challenge. The pathogenesis of Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) 55 infection is complex and effective therapy is currently lacking. Convalescent plasma 56 transfusion is safe and under investigation for effectiveness. 1-6 57 58 We report three hospitalized patients (Supplementary Table E1 and Figure E1 ) with X- (Table 1) . In the first two weeks of hospitalization, he received a red blood cell transfusion, broad-76 spectrum antibiotics, oxygen supplementation and albuterol treatments, and a dose of Deployment of 181 convalescent plasma for the prevention and treatment of COVID-19 Early 184 safety indicators of COVID-19 convalescent plasma in 5,000 patients Treatment of 5 Critically Ill Patients 186 With COVID-19 With Convalescent Plasma Effectiveness of convalescent plasma 188 therapy in severe COVID-19 patients Treatment with convalescent plasma 190 for COVID-19 patients in Wuhan Convalescent 193 plasma treatment of severe COVID-19: A matched control study A possible role 195 for B cells in COVID-19?
