Turbo Cancer
Turbo cancer is a term used for an anti-vaccine conspiracy theory that claims COVID-19 vaccines, especially mRNA vaccines, are causing vaccinated individuals to develop aggressive, fast-developing cancers. The claim has been debunked by medical experts, and the American Cancer Society has found no link between COVID-19 vaccines and cancer.
The "turbo cancer" theory has been widely embraced by anti-vaccine conspiracy theorists and QAnon adherents.
