Effectiveness of convalescent plasma therapy in severe COVID-19 patients

A new preliminary study shows a single 200 mL dose of convalescent plasma (CP) from COVID-19 patients who recently recovered shortened the duration of symptoms, improved oxygen levels and increased the clearance of the virus in patients who were still suffering from the disease. “One dose of convalescent plasma with a high concentration of neutralizing antibodies can rapidly reduce the viral load and tends to improve clinical outcomes”.
