Washington D.C: Treating patients suffering from coronavirus infection with transfusion of blood plasma from those who already recovered from the disease have been found to be safe and beneficial, a study suggested.

The new study, conducted over 20,000 hospitalized covid-19 patients, was based on a century-old idea in medicine that has been used against measles, influenza and Ebola. The treatment, also called convalescent plasma, found that people who recover from infection have virus-fighting antibodies floating in their blood, and transfusions of their plasma -- the clear liquid after blood cells are removed -- may give recipients' immune systems an assist in fighting off the virus, The Washington Post reported.
