Hope for the Use of Coronavirus plasma

Scientists will study if by injecting a person's plasma to heal a sick patient, they can see positive results in the patient.

This practice has long been recognized and used in the period of the 1918 flu, the measles ' epidemic in the 1930 ' s, and the Ebola in 2014.

When an infected person recovers, his blood still contains anti-body that has created anti-mucture organism. These anti-body responses are the immune system of the sick person to fight the microbe.

When a patient is injected with the plasma containing the serum, the patient can obtain additional immune protection.

This practice does not always work. Doctors believe that if the disease has advanced, it is difficult to achieve positive results.

Chinese doctors have treated some plasma patients, but only under experimental, clinical conditions, so it is not clear whether the practice will produce results on a large scale.

The Spanish company Griffiths has signed an agreement with the US government to collect plasma at blood donation centres. The company plans to separate the anti-body bodies recovered from the coronary for deeper scientific analysis against the disease.

This week the American Food and Drug Administration authorized American doctors to use plasma in patients in serious condition. / VOA/
