There is no conclusive evidence that the Pfizer-BioNTech COVID-19 vaccine contains graphene oxide
KEY TAKE AWAY
 Claims that a study from the University of Almería, Spain, found graphene oxide in the Pfizer-BioNTech COVID-19 vaccine, contain numerous inaccuracies. Firstly, the alleged vial of the Pfizer-BioNTech vaccine analyzed is of unknown origin and traceability. Secondly, the methodology used for the analysis, electron microscopy, is inconclusive. Thirdly, the list of ingredients in the Pfizer-BioNTech COVID-19 vaccine, which can be found in the vaccine’s package insert, don’t include graphene; these package inserts are rigorously reviewed by health authorities. Lastly, the analysis isn’t an official study from the University of Almería, which distanced itself from the analysis and its conclusions.
