Is the Pfizer coronavirus vaccine made up of 99.9% graphene oxide, a toxic compound?

The Pfizer vaccine does not contain any graphene oxide according to the ingredient list and Kit Longley, senior manager of science media relations at Pfizer. Videos on social media spread the false claim that the material made by oxidizing graphite was found in a vial of the Pfizer shot.

Chemical and medical experts who are not associated with Pfizer confirmed to The Associated Press that there is no way graphene oxide would be found in the vaccine.

“It is not in the ingredient list and there is no way it could be present,” said Allen Myerson, a professor of chemical engineering at the Massachusetts Institute of Technology.

There has been research on potentially using graphene oxide in other vaccines, but the amounts would not be toxic to human cells, according to Johns Hopkins infectious disease specialist Dr. Amesh Adalja.
