Key points

  • No CDC statement supports this claim.
  • CDC focuses on vaccine safety and effectiveness, not making such claims.
  • Such a statement would be highly unusual for the CDC to make.

Explanation

The Centers for Disease Control and Prevention (CDC) has not issued any public statements or reports claiming that COVID-19 vaccines are the largest carcinogenic exposure in history. The CDC's primary focus is on monitoring vaccine safety, effectiveness, and adverse events through various surveillance systems like V-safe and VAERS. Any such claim would be highly unusual for an organization dedicated to public health and would likely have been widely reported if it had occurred.
