evidence: The claim: Red Cross says people vaccinated against COVID-19 cannot donate plasma [...] But for anyone vaccinated with any of the COVID-19 shots authorized in the U.S. – namely, Moderna, Pfizer, and Johnson & Johnson – there are no deferral periods constraining blood or plasma donation. If the vaccine was received overseas or the brand unknown, the wait time could then be two weeks, according to a joint statement released on April 16 by the American Association of Blood Banks, America's Blood Centers and the American Red Cross. [...] The claim that COVID-19 vaccine recipients cannot donate plasma to the Red Cross is FALSE, based on our research. The Red Cross confirmed that it is accepting blood and plasma donations from people who have received a U.S.-authorized COVID-19 vaccine, and donors do not have to wait to give blood after receiving the vaccine. Taking a COVID-19 vaccine does not hinder a person's other antibodies.
