DNA Vaccines for Emerging Infectious Diseases: What If?

Abstract

A novel and powerful method for vaccine research, colloquially known as DNA vaccines, involves the deliberate introduction into tissues of a DNA plasmid carrying an antigen-coding gene that transfects cells in vivo and results in an immune response. DNA vaccines have several distinct advantages, which include ease of manipulation, use of a generic technology, simplicity of manufacture, and chemical and biological stability. In addition, DNA vaccines are a great leveler among researchers around the world because they provide unprecedented ease of experimentation. To facilitate diffusion of information, an Internet site has been established called The DNA Vaccine Web (URL:http://www.genweb.com/Dnavax/dnavax.html). In this review, a brief survey is undertaken of the experimental models and preclinical work on DNA vaccines to contribute to a greater awareness of the possibilities for emerging infectious diseases.
