Changes from baseline in HIV-1 viral load (ratio of each value over baseline value) were obtained using crude values and expressed in RNA copies/milliliter \[copies/mL\]. Baseline of HIV-1 viral load was defined as geometric mean of values measured in blood samples taken at Screening and at Week 0. The HIV type 1, represents the more aggressive virus form, largely responsible for the AIDS pandemic.

Changes from baseline in HIV-1 viral load (difference of each value minus baseline value) were obtained using log10-transformed values and expressed in log10-RNA copies/mL. Baseline of HIV-1 viral load was defined as geometric mean of values measured in blood samples taken at Screening and at Week 0. The HIV type 1, represents the more aggressive virus form, largely responsible for the AIDS pandemic.

Assessed solicited local symptoms were pain, redness and swelling. Any = occurrence of symptom regardless of intensity. Grade 3 Pain = pain that prevented normal every day activities. Grade 3 Redness/Swelling = redness or swelling associated with ulceration or secondary infection/phlebitis/sterile abscess/drainage. Medically attended (MA) Pain = pain causing inability to perform basic self-care function or Hospitalization indicated for management of pain. Medically attended Redness/Swelling = redness or swelling associated with necrosis.

An unsolicited AE covers any untoward medical occurrence in a clinical investigation subject temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product and reported in addition to those solicited during the clinical study and any solicited symptom with onset outside the specified period of follow-up for solicited symptoms. Any was defined as the occurrence of any unsolicited AE regardless of intensity grade or relation to vaccination. Grade 3 (G3) AE = an AE which prevented normal, everyday activities. Related = AE assessed by the investigator as related to the vaccination. Unsolicited AEs were tabulated following Dose 1 and Dose 2 vaccinations.

Any was defined as the occurrence of any unsolicited AE regardless of intensity grade or relation to vaccination. Grade 3 (G3) AE = an AE which prevented normal, everyday activities. Related = AE assessed by the investigator as related to the vaccination. Unsolicited AEs were tabulated following Dose 3 and across doses.

Serious adverse events (SAEs) assessed include medical occurrences that result in death, are life threatening, require hospitalization or prolongation of hospitalization or result in disability/incapacity.

Potentially Immune-Mediated Diseases (pIMDs) are a subset of AEs that include both clearly autoimmune diseases and also other inflammatory and/or neurologic disorders which may or may not have an autoimmune etiology.

Among the biochemical and haematological parameters with abnormal values were alanine aminotransferase \[ALT\], albumin \[ALB\], alkaline phosphatase \[ALP\], aspartate aminotransferase \[AST\], bilirubin (total) \[BIL\], creatinine \[CRE\], eosinophils \[EOS\], eosinophils/100 leukocytes \[EOS/100LEU\], bicarbonate \[BIC\], haemoglobin \[HGB\], potassium \[PTS\], lymphocytes \[LYM\], lymphocytes/100 leukocytes \[LYM/100LEU\], sodium \[SDI\], neutrophils \[NEU\], neutrophils/100 leukocytes \[NEU/100LEU\], platelet count \[PLC\], prothrombin time-international normalized ratio \[PTT\] and white blood cell count \[WBC\]. Assessed grades (G) for laboratory parameters were 0, 1 (mild), 2 (moderate), 3 (severe) and 4 (potentially life-threatening), according to DAIDS (division of AIDS table for grading the severity of adult and pediatric adverse events -Version 1.0).
