Abstract Tattooing is one of a number of DNA delivery methods which results in an efficient expression of an introduced gene in the epidermal and dermal layers of the skin. The tattoo procedure causes many minor mechanical injuries followed by hemorrhage necrosis inflammation and regeneration of the skin and thus non-specifically stimulates the immune system. DNA vaccines delivered by tattooing have been shown to induce higher specific humoral and cellular immune responses than intramuscularly injected DNA. In this study we focused on the comparison of DNA immunization protocols using different routes of administrations of DNA intradermal tattoo versus intramuscular injection and molecular adjuvants cardiotoxin pre-treatment or GM-CSF DNA codelivery . For this comparison we used the major capsid
