Convalescent plasma infusion might play a role in the coexistence of benefits and concerns of corticosteroid use. Antibodies contained in the convalescent plasma will suppress viruses.14 In an animal study, passively transferred antibodies can provide total protection as well as the maintenance of high levels of antibody titer until the host's immune responses could be increased to clear the viral infection. Besides, in vivo studies showed that the effects of neutralizing antibodies were not only limited to viral clearance, but also included acceleration of infected cell clearance.15
