US Grants Emergency Use Authorization for Blood Plasma as COVID-19 Treatment Steve Herman WHITE HOUSE - Calling it "a truly historic announcement," U.S. President Donald Trump on Sunday hailed a federal government emergency authorization for use of convalescent blood plasma that he declared would "save countless lives" of coronavirus patients. Trump and his health secretary, Alex Azar, at a briefing for reporters, noted a 35% decrease in mortality among those younger than 80 who were not on a respirator, a month after receiving the treatment early in the course of their disease. "We dream in drug development of something like a 35% mortality reduction," Azar, the secretary of Health and Human Services, said alongside the president. "This is a major advance in the treatment of patients." .
