Plasma treatment to be trialled for coronavirus

The UK is to try to use the blood of coronavirus survivors to treat hospital patients ill with the disease.

NHS Blood and Transplant (NHSBT) is asking people who have recovered from Covid-19 to donate their blood so they can assess the therapy in trials.

The hope is that the antibodies they have built up will help to clear the virus in others.

The US has already started a major project to study this, involving more than 1,500 hospitals.

When a person has Covid-19, their immune system responds by creating antibodies, which attack the virus.

Over time these build up and can be found in the plasma, the liquid portion of the blood.

NHSBT now wants to collect the plasma from recovered Covid-19 patients to see if it can be given to people who are currently ill with the virus.

A statement from the organisation said: "We envisage that this will be initially used in trials as a possible treatment for Covid-19.

"If fully approved, the trials will investigate whether convalescent plasma transfusions could improve a Covid-19 patient's speed of recovery and chances of survival.

"All clinical trials have to follow a rigorous approval process to protect patients and to ensure robust results are generated. We are working closely with the government and all relevant bodies to move through the approvals process as quickly as possible."
