Conventional vaccines contain either specific antigens from a pathogen, or attenuated viruses which stimulate an immune response in the vaccinated organism. DNA vaccines are members of the genetic vaccines, because they contain a genetic information (DNA or RNA) that codes for the cellular production (protein biosynthesis) of an antigen.
A genetic vaccine (also gene-based vaccine) is a vaccine that contains nucleic acids such as DNA or RNA that lead to protein biosynthesis of antigens within a cell. Genetic vaccines thus include DNA vaccines , RNA vaccines and viral vector vaccines .
Viral vector vaccines enable antigen expression within cells and induce a robust cytotoxic T cell response, unlike subunit vaccines which only confer humoral immunity. [7] [17] In order to transfer a nucleic acid coding for a specific protein to a cell, the vaccines employ a variant of a virus as its vector. This process helps to create ...

Cutter Laboratories was a family-owned pharmaceutical company located in Berkeley, California, founded by Edward Ahern Cutter in 1897.Cutter's early products included anthrax vaccine, hog cholera (swine fever) virus, and anti-hog cholera serum—and eventually a hog cholera vaccine.
After 45 years, authorities in California were finally able to tell the Gonzalez family who they believe killed their loved one. The Riverside County Sheriff’s Office used DNA and forensic ...
