COVID-19 mRNA vaccines do not cause or increase the risk of seven major cancers?

checkthis · automated fact-check · How we check · Reel by @nic.hulscher

Health authorities confirm there is no evidence COVID-19 vaccines cause cancer, and the cited figures and multi-country cancer links are unproven. Nicolas Hulscher claims on Newsmax that population studies and NCI data show COVID-19 vaccines increase the risk of seven major cancers. The National Cancer Institute and medical experts state there is no scientific evidence that COVID-19 vaccines cause or accelerate cancer (NCI, FactCheck.org). While a South Korean observational study noted statistical associations with six cancer types, observational data cannot establish causation (Biomarker Research).

What the Reel doesn't tell you

Observational study associations do not establish causation, and health agencies consistently find no evidence that COVID-19 vaccines cause or accelerate cancer.
The National Cancer Institute states there is no evidence that COVID-19 vaccines cause cancer, lead to recurrence, or lead to disease progression (NCI).
Memorial Sloan Kettering Cancer Center confirms COVID-19 mRNA vaccines do not cause cancer or make cancer return (MSKCC).

How it plays you

It wants you to think: “so the vaccines are a harmful and dangerous exposure that should be criminalized”

Statistical associations in observational data do not prove that vaccines cause cancer or justify criminal charges.
