Abstract
We characterized the antibody composition of coronavirus disease 2019 (COVID-19) convalescent plasma (CCP) and the immunologic responses of hospitalized COVID-19 patients after receiving CCP or nonimmune fresh frozen plasma. Despite selection of CCP with significantly higher total immunoglobulin G than recipients, neutralizing antibody levels did not differ between donor plasma and CCP recipients.
