Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Arm 1 (n=10): HIVIS DNA / MVA-CMDR
Arm 1 (n=10) will receive 1500 micrograms (0.5ml) HIVIS DNA IM by needle-free injection at weeks 0 and 4 followed by intramuscular (IM) needle injection of 1 X 108 IU/mL (1ml) MVA-CMDR at weeks 24 and 36 in the same arm as HIVIS DNA. Participants who have been randomized to receive HIVIS DNA and MVA-CMDR alone (ARM 1) will be administered Cervarix after week 72, the last study follow-up visit, if required. |
HIVIS DNA IM by needle-free injection at weeks 0 and 4 followed by intramuscular (IM) needle injection of 1 X 108 IU/mL (1ml) MVA-CMDR at weeks 24 and 36 in the same arm as HIVIS DNA.
|
Experimental: Arm 2 (n=10): HIVIS DNA + Cervarix/ / MVA-CMDR
Arm 2 (n=10) will receive 0.5 ml of Cervarix IM by needle injection followed by 1500 micrograms (0.5ml) per injection of HIVIS DNA IM by a needle-free injection device in the skin above (proximal to) the Cervarix injection (within 1.5 cm).
They will receive 1 X 108 IU/mL (1ml) MVA-CMDR IM by needle injection at weeks 24 and 36 in the same arm as HIVIS DNA.
They will also receive 0.5 ml Cervarix at the time of the first MVACMDR injection in the opposite arm from the MVA injection at week 24.

|
Experimental: Arm 3 (n=5): Cervarix
Arm 3 (n=5) will receive 0.5 ml of Cervarix by IM needle injection at weeks 0, 4 and 24.
