Red Cross Not Accepting Convalescent Plasma From anyone Who Has Received A COVID-19 Vaccination

In June of 2021 the Red Cross announced it would no longer accept convalescent plasma from anyone who has received a COVID -19 vaccine to help other COVID-19 patients in hospitals. That plasma is made up of antibodies from people who have recovered from the virus but the vaccine wipes out those antibodies making the convalescent plasma ineffective in treating other COVID-19 patients.
