Convalescent Plasma as Potential Therapy for Severe COVID-19 Pneumonia

COVID-19 convalescent plasma will be infused to patients with severe COVID-19 pneumonia to determine feasibility, safety and clinical outcome efficacy by survival at-28 days. Data will be compared with match control arm patients without plasma infusion
