evidence: COVID-19 vaccines were rigorously tested in clinical trials before they were permitted to be used in the general public. The Pfizer-BioNTech COVID-19 vaccine doesn’t contain graphene oxide nor is graphene listed on any credible ingredient lists of any COVID-19 vaccine provided by public health authorities and regulators. However, some have misrepresented a Pfizer document to claim otherwise. In fact, the document describes a microscopy study that was part of the structural characterization of the vaccine spike protein, in which scientists used graphene oxide as a support material for sample processing and visualization. Misrepresents source: The claim is based on a screenshot of a Pfizer document that omits important context. In fact, the FDA-released Pfizer document didn’t "confirm" that COVID-19 vaccines contain graphene oxide. The document discusses research procedures used in testing the vaccine, rather than the manufacture of the actual vaccine. [...] The document released by Pfizer doesn’t state that graphene oxide is an ingredient of its mRNA COVID-19 vaccine. Instead, it described a microscopy study used to assess the structure of the vaccine spike protein. The technique involved uses graphene oxide grids to stably arrange the samples for microscopy. This document doesn’t mention any use of graphene oxide during the manufacture of the vaccine, and no credible ingredient lists of the vaccine show graphene oxide as an ingredient.
