"The death rate in patients who were in special and critical conditions in ICU wards has reduced 50% after they received plasma in due time," Eshqi told reporters in an on-line press conference.
He added that the coronavirus patients who had received plasma have stayed 30% less at hospital and 50% less at ICU wards compared with others who were being treated through other methods.
Eshqi said that plasma therapy is now being practiced on 60 patients in regions which are in red situation of coronavirus epidemic.
Head of Iran's Razi Medical Institute Ali Es'haqi had announced in April that plasma therapy for patients diagnosed with coronavirus had already kicked off in the country.
Es'haqi said that due to the outbreak of COVID-19 in the country and studies on plasma therapy for patients suffering from it, joint meetings were held between Razi Institute, Alborz University of Medical Sciences and the Blood Transfusion Organization of Iran to start the implementation of this project in Alborz province as a joint research project.
"In this regard, Razi Institute will evaluate the level of antibodies of improved individuals for injection to patients and the relevant immune response in cooperation with Alborz University of Medical Sciences and the Iranian Blood Transfusion Organization," he added.
