Abstract DNA vaccination is a relatively recent development in vaccine methodology. It is now possible to undertake a rational step-by-step approach to DNA vaccine design. Strategies may include the incorporation of immunostimulatory sequences in the backbone of the plasmid co-expression of stimulatory molecules utilisation of localisation secretory signals and utilisation of the appropriate delivery system for example. However another important consideration is the utilisation of methods designed to optimise transgene expression. In this review we discuss the importance of regulatory elements kozak sequences and codon optimisation in transgene expression. Review In 1990 the direct gene transfer of plasmid DNA into mouse muscle in vivo without the need for a special delivery system was demonstrated 1 . Furthermore intramuscular inoculation with plasmid DNA encoding reporter genes induced protein .
