Are COVID vaccines known to be linked to increased risks for cancer?

COVID vaccines are neither linked to increased rinks for cancer nor can cause cancer, according to the Memorial Sloan Kettering Cancer Center.

False claims about COVID vaccines and cancer arose after Sloan Kettering researchers discovered that “messenger RNA inactivates tumor-suppressing proteins.” While the Pfizer and Moderna COVID-19 vaccines rely on mRNA to function, mRNA molecules that “inactivate tumor-suppressing proteins” are not the same ones found in mRNA-based vaccines. Thus, the vaccines do not deactivate any proteins that would stop the creation of tumors.

The claim was initially spread by Natural News, a far-right-leaning website known to spread and promote anti-vax conspiracy theories. The claim has been refuted by Sloan Kettering itself, with the institute noting that because the vaccines do not interact with or alter one’s DNA, they could not possibly cause cancer.

ABOUT THE CONTRIBUTOR
Between 2020 and 2022, under close editorial supervision, Gigafact contracted a group of freelance writers and editors to test the concepts for fact briefs and provide inputs to our software development process. We call this effort Gigafact Foundry. Over the course of these two years, Gigafact Foundry writers published over 1500 fact briefs in response to claims they found online. Their important work forms the basis of Gigafact formats and editorial guidelines, and is available to the public on Gigafact.org. Readers should be aware that while there is still a lot of relevant information to be found, not all fact briefs produced by Gigafact Foundry reflect Gigafact's current methods and standards for fact briefs. If you come across any that you feel are out of date and need to be looked at with fresh eyes, don't hesitate to contact us at support@gigafact.org.
