One particular video featuring a US pundit who claims the Pfizer-BioNTech Covid-19 vaccine is dangerous because it contains the nanoparticle graphene oxide has been watched more than a million times on social media.
Peters discusses the Pfizer-BioNTech vaccine with Jane Ruby — a self-described “health economist and New Right political pundit” whom AFP has fact-checked before.
But the claims are based on a study whose methodology experts have questioned, Pfizer said the substance is not used in the manufacturing of its shot, and researchers told AFP there is no evidence graphene oxide is used in any vaccines currently on the market.
“After investigating the contents of vaccines, 99% was found to be graphene oxide. Like asbestos, this causes cancer,” reads this Korean-language Facebook post on July 12, 2021.
“Graphene oxide was found in all vaccines commercially available,” the post adds.
But these posts are misleading, according to multiple experts.
Do Covid vaccines really contain Graphene oxide?
“No vaccines on the market [is] based on graphene oxide,” Dr. Park Jong-bo, a researcher at Biographene, a company that develops graphene-based medicine, told AFP on July 20, 2021.
Vaccines currently in use are “comprised of phospholipid layers, peptides or nucleic acids, and graphene oxide is not part of these categories,” Park said.
The claim that all commercially available vaccines were 99% made up of graphene oxide was “ungrounded in fact,” Professor Hong Byung-hee, an expert in nanomaterials at Seoul National University, told AFP on July 19, 2021.
“Graphene is being tested for biomedical purposes, including for vaccines, but these applications are still in an experimental phase and a long wait is expected before they become commercially available following clinical trials,” Hong said.
Hong added that the claim that graphene oxide is purportedly like asbestos and causes cancer is misleading.
“Graphene has a planar structure, and is very different from asbestos, which has a needle structure,” he explained.
“In the case of graphene oxide… there is some toxicity but relatively little, so the material is being widely researched for use in drug delivery systems and in vivo diagnostic sensors.”
Vaccines are available for some two dozen diseases including Covid-19, according to this list from the World Health Organization (WHO).
“The most commonly used vaccines have been around for decades, with millions of people receiving them safely every year,” the WHO states here.
“Following the introduction of a vaccine, close monitoring continues to detect any unexpected adverse side effects.”
