DNA Vaccines: Permanent Manipulation

Dr. Sherri Tenpenny, DO, AOBNMM, ABIHM tr

DNA vaccines, a type of genetic engineering, were first tinkered within the early 1990s. A small snip of DNA, say, from a herpes virus, makes its way into a bacterial “bubble” called a plasmid, by way of injection. When the plasmid-laden vaccine is injected, the cellular immune system gears up to eliminate the foreign protein (plasmid + viral DNA snip). And at the same time, the humoral immune system creates antibodies against the viral DNA. When a herpes virus enters the body, the memory T-cells and B-cells work together to attack the foreign virus. This eliminates the virus it and avoids infection.
