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 .
Nucleic acid vaccines use mRNA to give cells instructions on how to produce a desired protein. Libre de Droit/iStock via Getty ImagesThe two most successful coronavirus vaccines developed in the U ...
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.
They can generate T H and antibody responses, but not killer T cell responses. [citation needed] RNA vaccines and DNA vaccines are examples of third generation vaccines. [169] [170] [171] In 2016 a DNA vaccine for the Zika virus began testing at the National Institutes of Health. Separately, Inovio Pharmaceuticals and GeneOne Life Science began ...
