Health officials have sent out a rallying call to Covid-19 survivors to donatetheir blood plasma in Cambridge. The city is one of 23 across the country with a special donation centre.

Preliminary research suggests that three groups of patients have plasma which has the most potential to save lives. These include: patients over the age of 35, male Covid-19 survivors and patients who were ill enough to need hospital treatment.

NHSBT is collecting convalescent plasma for a major coronavirus treatment trial, and if the trial is successful, widespread use in hospitals. The antibody-rich plasma of people who have recovered can be transfused into people are struggling to develop their own immune response.

"Please help your NHS fight COVID-19. Convalescent plasma donation is safe and easy and you could save lives. If you get the call, please donate".
