DNA vaccines

DNA vaccination is a technique for protecting an organism against disease by injecting it with genetically engineered DNA to produce an immunological response. Nucleic acid vaccines are still experimental, and have been applied to a number of viral, bacterial and parasitic models of disease, as well as to several tumour models. Although unproven in the clinical setting, DNA vaccines have a number of potential advantages over conventional vaccines, including the ability to induce a wider range of immune response types.
