As of Aug. 13, more than 90,000 patients hospitalized in the U.S. with COVID-19 already had been given access to convalescent plasma through a national expanded use protocol (EAP) sponsored by the Mayo Clinic. The FDA’s decision Sunday to grant emergency use authorization (EUA) for the potential therapy will further expand access to convalescent plasma for hospitalized patients throughout the country at a time when fully approved COVID-19 treatments are nonexistent and even EUAs are few and far between.
