Myth #4: Myth: mRNA vaccines could potentially alter your DNA
A troubling myth that has been widely circulated on Facebook is that an mRNA vaccine can alter an individual’s genetic code.
Both Florian Krammer, a renowned professor of vaccinology at the Icahn School of Medicine at Mount Sinai, and Richard Kennedy, an immunologist, and co-director of the Mayo Clinic’s Vaccine Research Group, say this is not true for the simple reason that it’s not possible.
“Our genome is DNA and we have all of the enzymes and machinery to make copies of that,” says Kennedy.
“We don’t have any of the machinery in our cells to take the RNA and change it back into DNA. Otherwise, you would be doing that every time we’re infected with any virus.”
“The pathway from DNA to RNA is a one-way street,” Krammer adds.
“The other way doesn’t work. So it does not change your genome at all — and it could be safer than many other vaccines.”
Mark Lynas, a visiting fellow at Cornell University’s Alliance for Science, echoed their thoughts to Reuters.
“That’s just a myth, one often spread intentionally by anti-vaccination activists to deliberately generate confusion and mistrust,” Lynas said.
“Genetic modification would involve the deliberate insertion of foreign DNA into the nucleus of a human cell, and vaccines simply don’t do that.”
