A controversial paper that has not been peer-reviewed is being shared on social media as proof that the long-standing anti-vaccine claim that mRNA vaccines alters genomic DNA is true. In reality, the conclusions of the paper are being misrepresented. The paper itself specifically states that it is not claiming this, but contends that it is hypothetically possible. The study’s methodology and conclusions are contested. Reuters has fact-checked this misrepresentation of controversial research.
