What you may have heard
COVID-19 vaccines can cause cancer or increase the aggressiveness of existing cancers.
What the science tells us
The overwhelming body of scientific evidence indicates that COVID-19 vaccines are safe and do not cause cancer. Major health organizations and multiple studies support this conclusion.
Epidemiological Evidence:
- A comprehensive analysis of 81 studies involving 61,532 cancer patients showed no evidence linking COVID-19 vaccines to increased cancer risk or progression.
- National Cancer Institute and American Cancer Society Statements have stated that there is no data to suggest that COVID-19 vaccines cause cancer, make existing cancers more aggressive, or lead to cancer recurrence.
Laboratory Evidence/Supporting Evidence:
- Clinical trials and post-vaccination monitoring have demonstrated that the mRNA vaccines (Pfizer/BioNTech and Moderna) do not contain carcinogenic substances.
- Research shows that the vaccines are effective in generating an immune response without altering the DNA of human cells, a crucial factor that could potentially lead to cancer.

How to reduce your risk
- Maintain a healthy lifestyle, including a balanced diet and regular exercise, which can strengthen your immune system.
- Continue with regular cancer screenings and check-ups as recommended by your healthcare provider.
Bottom line
COVID-19 vaccines are safe and do not cause cancer. They play a critical role in protecting individuals, especially those with cancer, from severe COVID-19 complications.
