[edit] Summary
DNA vaccines are composed of a small, circular piece of DNA — called a DNA plasmid — that contains genes that code for proteins of a pathogen. When the vaccine is injected into the host, the inner machinery of the host cells “reads” the DNA and converts it into proteins from the pathogen. Recognizing that the proteins are foreign, the cells display them on their surface to alert the body’s immune system — both helper T cells, which spur the production of antibodies, and killer T cells, which kill infected cells outright.
