Professor of Immunology, Danny Altmann, talks us through his work looking at the way in which Covid-19 has left its mark on the immune system in cases of Long Covid.  He draws comparisons with other viruses to try and understand the long term prognosis for Long Covid sufferers, as well detailing his efforts to develop a potential blood test for diagnosis of the condition.  A brilliant mind, Professor Altmann does not shy away from political, ethical and moral debates arising from the impact of the disease.Living with Long Covid?
