Scientists find aberrant immune system in patients with virus could also be cause of ‘long Covid’
Dramatic levels of “friendly fire” from the immune system may drive severe Covid-19 disease and leave patients with “long Covid” – when medical problems persist for a significant time after the virus has been beaten – scientists have said.
Researchers at Yale University found that Covid-19 patients had large numbers of misguided antibodies in their blood that targeted the organs, tissues and the immune system itself, rather than fighting off the invading virus.
