Do DNA Fragments in COVID-19 mRNA Vaccines Cause Harm?

Dr. Paul Offit explains why it’s virtually impossible for DNA fragments in COVID-19 mRNA vaccines to cause harms, such as cancers or autoimmune diseases.
Dr. Offit describes what would have to happen in order for DNA fragments to cause harm by explaining three protective mechanisms in our cells that DNA fragments from mRNA vaccines cannot overcome. First, the cytoplasm has immune mechanisms and enzymes that destroy foreign DNA. Second, the fragments would have to enter the nucleus, which requires a nuclear membrane access signal that these DNA fragments don't have. Third, even if they were able to enter the nucleus, the fragments would need to have an enzyme called integrase to become part of our DNA, which they also don’t have.
These facts should be reassuring to anyone concerned about a health risk caused by DNA fragments in vaccines.
