However, one month later on, “no major big difference was famous concerning the convalescent plasma group and the placebo group” in conditions of clinical outcomes, with about 11% of patients dying in both equally teams, according to a staff led by Dr. V.A. Simonovich of the Italian Medical center of Buenos Aires.
