Convalescent Plasma Collection and Treatment in Pediatrics and Adults

"Each adult recipient will receive 1 units of plasma, each unit will consist of about 200 to 250 mL.~Each pediatric recipient will receive 10mL/kg up to 1 unit of plasma."

"Those that meet severe or critical criteria will be given 2 units if available or 1 unit if 2 units are not available.~Those that are given 1 unit may receive the second unit (or the remainder of the maximum pediatric weight calculated amount of plasma up to 1 additional unit) if they progress to severe or critical condition or if already in severe or critical condition but only received 1 unit secondary to shortages.~Each pediatric recipient will receive 10mL/kg up to 2 units of plasma."

Those that meet mild severity will be allowed to enroll in the study, but will not receive plasma unless there is progression of illness into the moderate/rapid progression or greater category.
