The problem is, we don't really have enough data to really understand how effective convalescent plasma is," Dr. Jonathan Reiner, a professor of medicine at George Washington University and a CNN medical analyst, told CNN Sunday. "We don't know compared to a placebo whether convalescent plasma is effective but we have recent data that suggests that people who receive convalescent plasma early, or earlier do better than those that get it later. EUAs make sense when there's real, clear evidence of benefit, and they should be evidence about what that evidence is," Caplan told CNN. Caplan said he's worried about whether there's a large enough supply of convalescent plasma, which relies on donations from Covid-19 survivors.
