There is no graphene oxide in Pfizer and Moderna vaccines. The mRNA is delivered through lipids just like it says on the box. Anti-vax grifters have taken advantage of the fact that both graphene oxide and lipids look visually similar under microscopic examination to make ridiculous claims that hundreds of employees at Pfizer, Moderna and FDA are in on a secret conspiracy to murder millions of people. Absence of any evidence that anyone has died from graphene oxide toxicity to date despite 250+ millions of vaccine jabs in the US alone ought to be enough to disabuse any rational person against such a ridiculous conspiracy theory.
