CUTHIVAC002 is a randomised Phase I study in healthy volunteers, aimed at exploring the safety and immunogenicity of two different modes of delivery of a deoxyribonucleic acid (DNA) HIV vaccine via combined intramuscular and intradermal methods with and without electroporation (EP), and boosted with recombinant HIV protein vaccine administered by intradermal injection without EP.~The aim of this study is to identify optimal DNA delivery conditions for promoting enhanced antibody responses to boosting with recombinant protein by the intradermal route. Healthy male and female volunteers aged 18 to 50 years old, who are at low risk of HIV infection, are to be recruited. The participants will be divided into 3 groups:~Group 1:~Participants will receive 1 x 0.15 ml (0.6 mg) DNA intradermal injections into the upper arm with EP and 1 x 0.5 ml (2 mg) intramuscular injection into the upper thigh without EP at Weeks 0, 4 & 8. And also 1 x 0.1 ml (50 μg) HIV recombinant protein by intradermal injection into the upper arm at Week 20 (final vaccination).~Group 2:~Participants will receive 1 x 0.15 ml (0.6 mg) DNA intradermal injections into the upper arm without EP and 1 x 0.5 ml (2 mg) intramuscular injection into the upper thigh with EP at weeks 0, 4 & 8. And also 1 x 0.1 ml (50 μg) HIV recombinant protein by intradermal injection into the upper arm at Week 20 (final vaccination).~Group 3:~Participants will receive 1 x 0.15 ml (0.6 mg) of DNA of intradermal injections into the upper arm with EP and 1 x 0.5 ml (2 mg) intramuscular injection into the upper thigh with EP at weeks 0, 4 & 8. And also 1 x 0.1 ml (50 μg) HIV recombinant protein by intradermal injection into the upper arm at Week 20 (final vaccination).~The investigators aim to have 8 participants complete the study in each group.
