A method is disclosed for enhanced vaccination and genetic vaccination of mammals. The vaccination is accomplished by delivering molecules such as proteins and nucleic acids into skeletal muscle and other cells residing in the skeletal muscle in vivo. The protein or nucleic acid is first injected into the muscle at one or multiple sites. Immediately or shortly after injection, electrodes are placed flanking the injection site and a specific amount of electrical current is passed through the muscle. The electrical current makes the muscle permeable, thus allowing the pharmaceutical drug or nucleic acid to enter the cell. The efficiency of transfer permits robust immune responses using DNA vaccines and produces sufficient secreted proteins for systemic biological activity to be observed.
