Nucleic acid strands (DNA or RNA) themselves are not highly antigenic, meaning that the immune system does not generally perceive them to be foreign. A principle reason of this is that although there are slight differences; DNA from a pathogen and DNA from a human are not so chemically different from one another that the immune system distinguishes between them.
