The question: Can mRNA vaccines change your DNA?
COVID-19 mRNA vaccines do not rewrite a recipient’s DNA.
Vaccine mRNA supplies instructions for making a protein. That process is different from editing the cell’s genome.
Show me why
Cells use messenger RNA as instructions for protein production. COVID-19 mRNA vaccines deliver such instructions for a viral protein so the immune system can respond. Protein production occurs in the cytoplasm; this is not a procedure for inserting a new sequence into a person’s chromosomes.
A common misconception
Changing which protein a cell produces temporarily is not the same as rewriting its DNA.
Where the limits are
This concerns COVID-19 mRNA vaccines, not all RNA technologies or gene therapies. It does not mean vaccination has no adverse effects. Cell-model findings alone do not establish genomic changes in vaccinated people.
How we know
CHOP explains why mRNA instructions differ from genomic DNA. A claim of genome alteration needs evidence of a vaccine-caused change in recipients’ chromosomes, not merely RNA or protein production. This entry uses the mechanism discussion, not the source’s older predictions about transmission.
What would change this conclusion?
Reproducible evidence of vaccine-caused genomic integration in recipients, with contamination and alternative explanations excluded, would require reassessment.
