evidence: On July 28, 2021, internet personality Stew Peters interviewed ex Pfizer staffer Kingston. She claimed there was "indisputable documentation" that proves mRNA COVID-19 vaccines (Pfizer and Moderna) contain a "poison" known as graphene oxide. [...] There have been multiple claims made online which say that the Pfizer vaccine contains 99% graphene oxide, a substance which is derived from graphite. The claims originate from a Spanish study and have been circulating in English (across the UK and the US), in Spanish and in Portuguese. [...] In reality, there's no graphene oxide in the Pfizer vaccine, according to the ingredient list and Kit Longley, senior manager of science media relations at Pfizer, reported AP.
