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.
