“Injecting RNA into a person doesn’t do anything to the DNA of a human cell,” says Prof Jeffrey Almond of Oxford University.
It works by giving the body instructions to produce a protein which is present on the surface of the coronavirus.
The immune system then learns to recognise and produce antibodies against the protein.
The BBC asked three independent scientists about this. They said that the coronavirus vaccine would not alter human DNA.
The fear that a vaccine will somehow change your DNA is one we’ve seen aired regularly on social media.
