WHO advises against use of convalescent plasma therapy for Covid treatment


Paris: Convalescent plasma therapy had at one point been almost considered a miracle therapy for treatment of Covid-19. Now, the World Health Organization (WHO) has strongly advised against the use of this therapy to treat the infection.

The convalescent plasma therapy involves separating plasma from the blood of patients who have recovered from Covid-19 and then administering it to Covid patients.

This plasma, it was argued, has antibodies that can fight the coronavirus and stop it from replicating, thus aiding recovery.

The WHO on Tuesday said that convalescent plasma should not be administered to patients with mild or moderate illness. Even for severely infected or critical patients, it should be just a part of a clinical trial, the agency has said.

“Current evidence shows that it does not improve survival not reduce the need for mechanical ventilation, and it is costly and time-consuming to administer,” as per the WHO’s advice published in the British Medical Journal.

The recommendation is based on evidence from 16 trials that covered 16,236 patients across all categories of infection—non-severe, severe and critical.

In India too, convalescent plasma had been administered to critically ill patients last year. However, in May this year, the ICMR had dropped the convalescent plasma therapy from its treatment protocol for Covid.
