There are multiple COVID-19 conspiracy theories, including claims that messenger RNA (mRNA) vaccines alter the function of the human genetic code. Government and private experts say that is not how mRNA works.
Dr. James Lawler, a board-certified infectious disease specialist with Nebraska Medicine, says this regarding claims that mRNA alters genetics:
"That is just not true. They are not medical devices ... it doesn't change your chromosomes."
The Centers for Disease Control and Prevention also addressed such claims in a vaccine fact sheet, saying mRNA vaccines are not electrical devices and do not interact with human DNA "in any way."
