Optimization strategies for DNA vaccines.
DNA immunization is a relatively new vaccination strategy that involves the direct introduction into the host of plasmid DNA encoding the desired antigen. The DNA enters host cells and results in immune responses following in vivo expression of the antigen. Although DNA-based immunization works well in animal models for the induction of both humoral and cell-mediated immune responses, its success in humans has been limited. This paper discusses different approaches that have attempted to optimize DNA vaccines, and presents results evaluating some of these approaches in mice.
