Prior randomized trials of convalescent plasma in COVID-19 have had disappointing results. However, these trials included patients with severe illness who were many days (if not weeks) into the course of their illness. To date, it was hypothesized, but unknown, that the benefit would be in patients very early in the course of their illness. We cover an RCT by Libster et al in NEJM on convalescent plasma in older patients with mild COVID-19. Show notes/references: FOAMcast.org Thanks for listening! Lauren Westafer and Jeremy Faust
