Evaluating the Safety of and Immune Response to HIV-MAG DNA Vaccine With or Without Plasmid IL-12 Adjuvant Delivered Intramuscularly Via Electroporation Followed by VSV-gag HIV Vaccine Boost in Healthy, HIV-Uninfected Adults

Summary

Some vaccines may work better when given together with another substance known as an adjuvant or when given with an experimental procedure called electroporation (EP). EP is a method where an electric pulse is administered to the same muscle where the vaccine injection is given. The addition of the adjuvant to the vaccine and the delivery with EP may increase a person's immune response to the vaccine. Combination approaches such as a DNA vaccine followed by live vector boost may also increase a person's immune response to the vaccine components. All of these interventions will be tested in this study. This study will evaluate the safety and tolerability of and immune response to an HIV DNA vaccine with or without plasmid IL-12 adjuvant, when given by EP and followed by a live vector vaccine given IM by needle and syringe in healthy, HIV-uninfected adults.
