This document released under FOIA describes a study that involved the use of graphene oxide:
Title: "StructuralandBiophysicalCharacterizationofSARS-CoV-2SpikeGlycoprotein (P2 S) as a Vaccine Antigen"
"The purpose of this study was to express and characterize the vaccine antigen encoded by BNT152b2"
This has nothing to do with the ingredients of the vaccine or the manufacturing process.
The document describes the process of getting cryo-electron microscopy images of the spike protein.
