There is no danger from blood transfusions that include blood from COVID-19 vaccinated donors, health experts said.
Vaccine components are not found in the bloodstream, an American Red Cross spokesperson said.
COVID-19 vaccine skeptics for three years now have baselessly claimed that blood donated by vaccine recipients is unsafe.
"You’re. In. Danger," a Nov. 25 Instagram post’s caption read. It shared a screenshot of a Sept. 13, 2022, American Red Cross X post that said, "We don't label blood products as containing vaccinated or unvaccinated blood as the COVID-19 vaccine does not enter the bloodstream & poses no safety risks to the recipient."
The post was flagged as part of Meta’s efforts to combat false news and misinformation on its News Feed. (Read more about our partnership with Meta, which owns Facebook and Instagram.)
American Red Cross spokesperson Daniel Parra told PolitiFact, "Blood donations from individuals who have received a COVID-19 vaccine are safe for transfusion."
Like other vaccines, including for influenza, Parra said, the COVID-19 vaccines are designed to generate an immune response. "Vaccine components themselves are not found within the bloodstream," he said.
Parra said all U.S. blood collectors follow eligibility guidelines set by the U.S. Food and Drug Administration.
In a Nov. 27 statement to PolitiFact, the FDA said it "takes very seriously its responsibility to ensure the safety of the nation’s blood supply" and pointed us to guidance it issued in 2022 about COVID-19 and blood donation.
The FDA hasn’t required or recommended delays in blood donations of people after they received COVID-19 vaccines, the statement said. The FDA’s statement added that there’s "no medical or scientific" justification for seeking donations from only unvaccinated people.
Nevertheless, the false narrative has fueled the creation of anti-vaccine networks in which people can seek blood supposedly donated by unvaccinated people. In October, an FDA advisory said directed blood donation requests "lack scientific support" and urged people to "be cautious about websites that offer memberships" for blood "from individuals who have not been vaccinated for COVID-19."
In January, the American Red Cross also issued a joint statement with America’s Blood Centers and the Association for the Advancement of Blood & Biotherapies reiterating the safety of blood donations from COVID-19 vaccinated people.
"COVID-19 vaccines do not replicate, and all blood donations offer the same life-saving therapeutic benefits, regardless of the vaccination status of the donor," the statement said.
The claim that blood transfusions from donors who have been vaccinated against COVID-19 endanger recipients has no basis in science, health experts said. We rate the claim False.
