The idea of plasma treatment with the blood of those recovering from Covid-19 is based on the fact that the antibodies to the Corona virus in it can neutralize the virus and thus prevent it from multiplying and stop tissue damage in patients.
Several studies on plasma from blood recovered from Covid-19 have not demonstrated any clear benefit in patients with severe symptoms.
An American study was halted in March after it indicated that it was unlikely that this plasma would help patients with mild or moderate symptoms.
The World Health Organization said, on Monday, that this method of treatment is expensive and wastes a lot of time.
And the World Health Organization indicated that a committee composed of international experts strongly recommended not to use plasma from the blood of recovered COVID-19 patients to treat patients with mild symptoms.
The recommendation, published in the British Medical Journal, was based on the results of 16 trials involving 16,236 asymptomatic COVID-19 patients.
