Brief summary
The COVID-19 pandemic has been spreading continuously, and in Brazil, until August 18, 2020, there have been more than 3,359,000 cases with more than 108,536 deaths, with daily increases. The present study proposes to evaluate the efficacy and safety of using convalescent plasma for treating patients with COVID-19 pneumonia without indication of ventilatory support.
Interventions
The intervention group will receive 400 mL of convalescent plasma with a SARS-CoV-2 antispike antibody titer with a dilution ≥ 1: 320.
