False claims that COVID-19 vaccines cause turbo cancers

False narratives that mRNA vaccines cause turbo cancers are circulating across platforms and in English and Spanish language networks. Specifically, they claim that turbo cancers are occurring more rapidly, particularly in young adults, that the CDC is reclassifying cancer deaths as COVID-19 deaths to cover up rising turbo cancers, and that a Pfizer study proves that the COVID-19 vaccine caused turbo cancers in mice.

Risk level: Medium

Recommendation: Vaccine opponents are using understandable fears about cancer to push false claims. If presented with these concerns, doctors and other health care providers may emphasize that there is no evidence showing that COVID-19 vaccines cause cancer. Messaging may also point out the tactics of vaccine opponents, especially the use of emotional language and fear.
