In the absence of drugs to cure Coronavirus infection or vaccines to prevent COVID-19, currently, plasma therapy is being seen as a potential treatment for critically ill-patients. The therapy is based on the principle that the blood of a recovered patient is rich in antibodies needed to combat COVID-19. Plasma Therapy involves transfusion of antibodies from someone who has recovered from COVID-19 (convalescent coronavirus patient) into a critical patient. The antibodies help COVID-19 patients' immune systems fight the virus more efficiently.
