Oft-repeated claim again debunked: Experts say still no evidence that COVID-19 vaccines cause cancer

A video shared on Facebook tied COVID-19 vaccines to cancers that rapidly accelerate to Stage 4, the most advanced stage of cancer.

A woman narrating the video pegged the claim to Dr. Ryan Cole, an Idaho pathologist. 

Cole has been "looking at the unusual cancers that are exploding right into Stage 4," the woman said in the video. Those cancer cells, she said, have "the spike protein." 

The video doesn’t say that Cole is possibly facing sanctions after the Washington state Medical Commission filed unprofessional conduct charges against him for allegedly spreading COVID-19 misinformation.

The post was flagged as part of Facebook’s efforts to combat false news and misinformation on its News Feed. (Read more about our partnership with Meta, which owns Facebook and Instagram.)

COVID-19 mRNA (messenger RNA) vaccines use the human body’s natural immune response to their advantage. The shot contains the recipe for making the molecule known as the spike protein, which the COVID-19 virus uses to bind to cells. Once the cell receives these instructions, it creates the protein and displays it on its surface. The immune system then spots the unknown protein and makes antibodies to fight it.

We found an August article about Cole on Natural News, a website known for circulating false information about vaccines. It said that Cole believed that spike proteins in COVID-19 vaccines hurt the body’s immune system and caused an increase in cancer.

Video shows Russian President Vladimir Putin saying Biblical figures were “all Black.”

But we’ve repeatedly reported that scientific and medical researchers have found no evidence that the vaccines cause cancer.

Other fact-checkers have also debunked such claims.

The Memorial Sloan Kettering Cancer Center in New York, in an article about COVID-19 vaccine myths, said: "None of the vaccines interact with or alter your DNA in any way, and therefore cannot cause cancer." 

We’ve also reported that the vaccines’ spike protein are not toxic and not otherwise harmful to the body.

On Jan. 9, the Medical Commission in Washington, where Cole is also licensed to practice, filed unprofessional conduct charges against him. 

The charges allege that Cole made numerous false and misleading public statements about the COVID-19 pandemic and vaccines, including that the vaccines can lead to cancer, and that he gave negligent care to prevent or treat COVID-19 in four patients.

Cole denied to the commission that he advised people not to be vaccinated for COVID-19, according to the charges.

With no evidence that COVID-19 vaccines cause cancer, we rate the Facebook post False.
