Arm Intervention/treatment
Experimental: VAC-3S
32µg/ml corresponding to 16µg/vaccination
Biological: VAC-3S
Administered via intra-muscular injection in the arm

Primary Outcome Measures :
  1. Number of patients who tolerated 3 vaccinations with VAC-3S 16µg/mL at 4-weeks interval determined by safety parameter changes according to the DAIDS (Division of Acquired Immunodeficiency Syndrome) Adverse Events (AE) Grading Table. [ Time Frame: From Day 0 to week 16 ]

Secondary Outcome Measures :
  1. Number of patients who tolerated a fourth booster injection of VAC-3S 16µg/mL determined by safety parameter changes according to the DAIDS (Division of Acquired Immunodeficiency Syndrome) Adverse Events (AE) Grading Table. [ Time Frame: From Week 16 to Week 48 ]
  2. Anti-3S antibody titers [ Time Frame: From Day 0 to Week 48 ]
  3. Markers of progression to AIDS. Markers include CD4+ cell count, viral load, and phenotypic markers of lymphocyte differentiation and activation [ Time Frame: From Day 0 to Week 48 ]

  • Nadir CD4+ T cell count ≥ 100 cells/mm3,
  • Contraception in women with child-bearing potential,
  • A total anti-3S titer ≥ 20 A.U. at any time point of IVVAC-3S/P1 clinical trial,
  • Per protocol subject having completed the IVVAC-3S/P1 study.
  • Patient affiliated to a social security system,
  • Patient who has understood the protocol design and provided a signed written informed consent form,
  • Patient who is willing and capable of cooperating to the extent and degree required by the protocol,
  • Patient whom the investigator believes he/she can and will comply with the requirements of the protocol (e.g. completion of the diary cards, return for follow-up visits) and he/she will be available for all scheduled visits at the investigational site.

Exclusion Criteria:

  • Administration of VAC-3S in the past year,
  • Chronic active liver disease,
  • History of HCV co-infection or ongoing replicating HCV (positive RT-PCR) or HBV (positive HbS Ag) coinfection,
  • Any immunotherapy (e.g. IL-2, IL-7, growth hormone…) in the past year at the exception of VAC-3S,
  • Any immunosuppressive therapy (glucocorticoids, cyclosporine, methotrexate) or chronic non-steroidal anti-inflammatory treatment in the past month,
  • Ongoing pregnancy,
  • Breastfeeding women,
  • Patient with known sensitivities to investigational drug (see please the CIB),
  • History of allergy to any vaccine,
  • Any severe chronic condition that would interfere with the study,
  • History of auto-immune disease,
  • Organ transplant,
  • Splenectomy,
  • Psychiatric disorder significant enough to hinder participation as assessed by the investigator,
  • Patient who has participated in a clinical research trial in the 30 days preceding the screening visit (V-1M-1).
  • Patients with contraindications to intramuscular injections including, but not limited to, patients with thrombocytopenia and/or anomalies of the coagulation system,
  • Any uncontrolled chronic or acute condition that in the opinion of the investigator would compromise the safety of the patient or the ability to properly administer the study.
