Search for Ebola cure goes on as remedy based on survivors' blood underwhelms

Study shows that treatment based on transfusion of plasma extracted from blood of recovered patients does not significantly improve survival rates

Hopes that the blood of Ebola survivors might contain a ready-made cure for the virus have been dashed after the world's largest study of the treatment showed it did not save extra lives.

European scientists had hoped that plasma extracted from the blood of recovered patients might prove to be a therapy for future outbreaks of the disease because of the high levels of antibodies that remain in the plasma beyond recovery.
