Plasma is the clear, yellowish liquid part of the blood which carries red and white blood cells and platelets around the body. After an infection, plasma is often packed with antibodies generated by the immune system. Use of someones blood plasma that contains antibodies against a virus or bacteria to treat an infection in someone else, is not a new technology and although usually safe, is not entirely without risk, said Clarke, who was not involved in the new study. This convalescent plasma therapy was used during the 1918 flu pandemic, as well as during more recent global health emergencies, treating patients with Sars or Ebola. As such, it is sometimes harvested from people who have recovered from a disease and transfused into patients who are fighting it.
