COVID-19 convalescent plasma (CCP), from donors recovered from severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection, is one of the limited therapeutic options currently available for the treatment of critically ill patients with COVID-19. There is growing evidence that CCP may reduce viral loads and disease severity; and reduce mortality. However, concerns about the risk of transfusion-transmitted infections (TTI) and other complications associated with transfusion of plasma, remain. Amotosalen/UVA pathogen reduction treatment (A/UVA-PRT) of plasma offers a mitigation of TTI risk, and when combined with pooling has the potential to increase the diversity of the polyclonal SARS-CoV-2 neutralizing antibodies.
