  • Subjects must be HIV-positive and under care of a physician for at least 6 months.
  • Subjects must have a CD4+T cell count >= 250 cells/mm3 at screening.
  • Subjects must be stable on highly active antiretroviral therapy for at least 6 months, with an undetectable HIV viral load level at screening.

Additional inclusion criteria for subjects to be enrolled in HIV+ treatment naïve cohort:

  • Subjects must be HIV-positive and under care of a physician for at least 6 months
  • Subjects must be highly active antiretroviral therapy-naïve (never received anti-retroviral therapy after HIV diagnosis)
  • Subjects must have a CD4 + T cell count above 350 cells/mm3 at screening.
  • Subjects for whom commencement of highly active antiretroviral therapy is not expected based on current assessment within next year.
  • Subjects must have a viral load between 5000 - 80000 copies/mL at screening.

Additional inclusion criteria for subjects to be enrolled in HIV-negative cohort

• Subjects must be negative for HIV-1.

Exclusion Criteria:

  • Use of any investigational or non-registered product other than the study vaccine within 30 days preceding the first dose of study vaccine, or planned use during the study period.
  • Administration of a registered live vaccine not foreseen by the study within 30 days preceding the first dose of study vaccine and administration of a registered inactivated vaccine within 14 days preceding the first dose of study vaccine.
  • History of previous administration of experimental Mtb vaccines.
  • History of previous exposure to components of the investigational vaccine within 30 days preceding the first dose of study vaccine
  • Chronic administration of immunosuppressant or other immune-modifying drugs within six months prior to the first vaccine/product dose. For corticosteroids, this will mean prednisone >= 20 mg/kg/day, or equivalent. Inhaled and topical steroids are allowed.
  • Any condition or illness or medication, which in the opinion of the Investigator might interfere with the evaluation of the safety or immunogenicity of the vaccine.
  • Planned participation or participation in another experimental protocol with an experimental product during the study period.
  • Administration of any immunoglobulin, any immunotherapy and/or any blood products within the three months preceding the first dose of study vaccination, or planned administrations during the study period.
  • Subjects taking any of the following medication: chronic administration of systemic steroids, interleukins, systemic interferon or systemic chemotherapy.
  • History of allergic reactions or anaphylaxis to any drug or vaccine.
  • History of allergic disease or reactions likely to be exacerbated by any component of the vaccine.
  • History of chronic alcohol consumption and/or drug abuse which in the Investigator's opinion would put the subject at risk.
  • Pregnant female, lactating female or female planning to become pregnant or stop contraception.
  • Acute or chronic clinically relevant pulmonary, cardiovascular, hepatic or renal function abnormality as determined by physical examination or laboratory screening tests.

Additional exclusion criteria for subjects to be enrolled in HIV+ on highly active antiretroviral therapy cohort:

  • Any change in anti-retroviral drug regimen within 12 weeks prior to screening.
  • Any chronic drug therapy, other than highly active antiretroviral therapy or prophylaxis for opportunistic HIV related infections, birth control pills, anti-histamines for seasonal allergies and SSRIs.
