Plasma is the clear, yellowish liquid part of the blood which carries red and white blood cells and platelets around the body. While this is a blow to the use of plasma therapy for Covid-19, it should not be abandoned, there may be ways to refine it as a treatment and deliver solid, demonstrable benefits, Clarke said in a written statement distributed by the UK-based Science Media Centre. Prof Paul Morgan, the director of the Systems Immunity Research Institute at Cardiff University and a member of the British Society for Immunologys expert taskforce on immunology and Covid-19, said there were other reasons for optimism. But such speculation needs to be tested  we cant just rely on an educated guess. After an infection, plasma is often packed with antibodies generated by the immune system.
