People in South Africa who have recovered from the Covid-19 coronavirus are donating their blood to help others who are trying to fight off the disease that has so far claimed more than 200 lives and infected more than 10 000 people in the country

At least 30 Covid-19 survivors have registered to donate their blood to the SA National Blood Service to be used in a large clinical trial to see if their plasma, once separated from their blood, can help treat patients who have a moderate or severe form of Covid-19.

We don’t know if it will work, but the idea is to provide antibodies passively for the patients to fight the disease.Blood from Covid-19 survivors can be a rich source of antibodies or proteins that the immune system makes to attack the SARS-CoV-2 virus, which causes Covid-19.

The May editorial in the journal, Lancet Haematology, however, points out: “Definitive clinical evidence showing the efficacy of convalescent plasma is scarce.” The trials are part of an initiative by the US National Covid-19 Convalescent Plasma Project, a group of physicians and scientists from 57 institutions in 46 states.

Vermeulen says the procedure is like giving blood, except that the blood drawn from the patient is run through a machine to extract the plasma and the red and white cells are then returned to the donor.
