The efficacy of SARS-CoV2 standard single donor convalescent plasma varied according to the application time and most importantly the amount of antibody that is administered. Single donor plasma has some drawbacks; such as the insufficient levels of neutralizing antibody activities, the requirements of blood group compatibility, and the risk of infection transmission. In this study, the efficacy and safety of pathogen inactivated, isohemagglutinin-depleted (concentrated) and pooled convalescent plasma was investigated.
Pathogen-free, concentrated, pooled convalescent plasma has higher SARS-CoV2 antibody titers and neutralizing antibody activities, without requiring blood group compatibility that allows patient accessibility in a shorter time and has safe plasma characteristic.
