evidence: The American Red Cross wants to remind the public that receiving a COVID-19 vaccine does not make you ineligible to donate blood and blood donations from those who have been vaccinated for COVID-19 are safe for transfusion. The Red Cross, like all blood collectors in the U.S., is required to follow the eligibility guidelines set by the FDA, including guidance regarding blood donor eligibility related to those who receive vaccinations, such as a COVID-19 vaccine, and others. [...] Blood donations from those who have been vaccinated for COVID-19 are safe for transfusion. Similar to other vaccines such as measles, mumps or influenza, the COVID-19 vaccine is designed to generate an immune response to help protect an individual from illness, but vaccine components themselves do not replicate through blood transfusions or alter a blood recipients’ DNA. Additionally, a donor’s immune response is not impacted by giving blood. Donating blood after receiving a COVID-19 vaccine does not reduce a donor’s protection from the virus.
