Claim: The COVID-19 vaccine alters human DNA
Multiple peer reviewed studies and regulators confirm that mRNA vaccines do not interact with or alter DNA. The mRNA does not enter the nucleus where DNA is kept and is degraded by normal cellular processes after use. Post-authorisation safety monitoring has not shown evidence of genomic alteration from authorised vaccines.
Evidence
- Nature: How mRNA vaccines work
- CDC: Myths and facts about COVID-19 vaccines
- EMA: COVID-19 vaccines key facts
- WHO: How mRNA vaccines work
- NEJM study via NCBI: Safety and efficacy of BNT162b2

Misinformation pattern
This claim fits a science distortion pattern. It borrows real terms such as DNA and nucleus to imply a mechanism that is not supported by the evidence, and misrepresents how mRNA is handled in cells.
Claim: The COVID-19 vaccine changes your DNA
The vaccine gives your cells a set of instructions to help you build protection. Those instructions stay outside the part of the cell that holds your DNA. Your body then breaks the instructions down. Your DNA is not changed.
Evidence
These are trusted science and health sources.
Misinformation pattern
The claim uses science words in a confusing way. It makes people think the vaccine goes into your DNA. It does not.
