evidence: A post on Instagram claims the Red Cross has said people vaccinated against Covid-19 are prohibited from donating blood for certain purposes as the vaccine "wipes out" some antibodies present in blood. [...] This is false. The American Red Cross says: "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." It adds "This is not accurate." [...] The American Red Cross is still accepting blood donations from people who have been vaccinated.
