What you need to know
- COVID-19 vaccines do not cause “turbo cancer” or contain SV40, a virus that has been suspected of causing cancer.
- There is no link between rising cancer rates and COVID-19 vaccines.
- Staying up to date on COVID-19 vaccines is a safe, free way to support long-term health.
Myths that COVID-19 vaccines cause cancer have been circulating since the vaccines were first developed. These false claims resurfaced last month after Princess Kate Middleton announced that she is undergoing cancer treatment, with some vaccine opponents falsely claiming Middleton has a “turbo cancer” caused by COVID-19 vaccines.
Here’s what we know: “Turbo cancer” is a made-up term for a fake phenomenon, and there is strong evidence that COVID-19 vaccines do not cause cancer or increase cancer risk.
Read on to learn how to recognize false claims about COVID-19 vaccines and cancer.
Do COVID-19 vaccines contain cancer-causing ingredients?
No. Some vaccine opponents claim that COVID-19 vaccines contain SV40, a virus that has been suspected of causing cancer. This claim is false.
A piece of SV40’s DNA sequence—called a “promoter”—was used as starting material to develop COVID-19 vaccines, but the virus itself is not present in the vaccines. The promoter does not contain the part of the virus that enters the cell nucleus, so it poses no risk.
COVID-19 vaccines and their ingredients have been rigorously studied in millions of people worldwide and have been determined to be safe. The National Cancer Institute and the American Cancer Society agree that COVID-19 vaccines do not increase cancer risk or accelerate cancer growth.
Why are cancer rates rising in the U.S.?
Since the 1990s, cancer rates have been on the rise globally and in the U.S., most notably in people under 50. Increased cancer screening may partially explain the rising number of cancer diagnoses. Exposure to air pollution and lifestyle factors like tobacco use, alcohol use, and diet may also be contributing factors.
What are the benefits of staying up to date on COVID-19 vaccines?
Staying up to date on COVID-19 vaccines is a safe way to protect our long-term health. COVID-19 vaccines prevent severe illness, hospitalization, death, and long COVID.
The CDC says staying up to date on COVID-19 vaccines is a safer and more reliable way to build protection against COVID-19 than getting sick from COVID-19.
