Methods of extraction and administration of Convalescent Plasma (CP). a a convalescent donor who has developed antibodies after recovering from the disease could donate plasma (usually through plasmapheresis) that includes antibodies against SARS-CoV-2 for direct transfusion and other antibodies (passive immunity) to patients with severe symptoms of the disease. b plasma from a group of donors could be used to identify and purify specific antibodies against SARS-CoV-2, eliminating other antibodies and proteins, making this method an alternative for passive immunization
