evidence: The Red Cross, like all blood collectors in the U.S., is required to follow the eligibility guidelines by the U.S. Food and Drug Administration, including guidance regarding blood donor eligibility related to those who receive a COVID-19 vaccine. You can donate after COVID-19 vaccination. Please come prepared to share the manufacturer name of the vaccine you received. [...] Q: I’ve heard claims that the Red Cross refuses to accept convalescent plasma from individuals who have received a COVID-19 vaccine because it wipes out the antibodies. Is this true? A: There are claims circulating that incorrectly state that the Red Cross will not accept convalescent plasma donations from those who have received the COVID-19 vaccine because "the vaccine wipes out those antibodies making the convalescent plasma ineffective in treating other COVID-19 patients." This is not accurate.
