Biochemical laboratory parameters include alanine aminotransferase [ALT], aspartate aminotransferase [AST], creatinine, urea nitrogen and uric acid. Categories reported when comparing Day 1 (pre-vaccination dose 1=baseline) and Day 8 hematological and biochemical laboratory results are defined as follows: <parameter>-<range at baseline>-<range at timing> (e.g. ALT-Within-Within). Ranges level being classified as below, within or above the normal ranges.

  7. Number of Subjects Presenting Change From Baseline in Hematology and Biochemistry With Respect of Normal Laboratory Ranges, After Second Vaccine Dose When Compared to Day 61 [ Time Frame: At 7 days after the second vaccine dose (i.e at Day 68 versus Day 61) ]

  10. Number of Subjects With Any Serious Adverse Events (SAEs) up to 30 Days After the Second Vaccination [ Time Frame: From Day 1 up to 30 days after the second vaccination (Day 91) ]
    A SAE is any untoward medical occurrence that results in death, is life-threatening, requires hospitalization or prolongation of existing hospitalization or results in disability/incapacity.

  11. Number of Subjects With Any Potential Immune-mediated Diseases (pIMDs) up to 30 Days After the Second Vaccination [ Time Frame: From Day 1 up to 30 days after the second vaccination (Day 91) ]
    pIMDs are a subset of AEs that include autoimmune diseases and other inflammatory and/or neurologic disorders of interest which may or may not have an autoimmune etiology


Secondary Outcome Measures :
  1. Humoral Immune Response With Respect to Components of the Investigational Vaccine in Terms of Neutralizing Antibody Titers Against RSV- Serotype A [ Time Frame: At pre-vaccination (Day 1), 30 days post-Dose 1 (Day 31), on the day of second vaccination (Day 61) and 30 days post-Dose 2 (Day 91) ]
    Serological assays for the determination of functional antibodies against RSV-A were performed by neutralization assay. Anti RSV-A neutralizing antibody titers are given as geometric mean titers (GMTs) and expressed as Estimated Dose: serum dilution giving a 60% reduction of the signal compared to a control without serum (ED60). The cut-off of the assay is 18 ED60.

  2. Humoral Immune Response With Respect to Components of the Investigational Vaccine in Terms of RSVPreF3-specific Immunoglobulin G (IgG) Antibody Concentrations [ Time Frame: At pre-vaccination (Day 1), 30 days post-Dose 1 (Day 31), on the day of second vaccination (Day 61) and 30 days post-Dose 2 (Day 91) ]
    The detection and the quantification of total IgG antibodies directed against RSVPreF3 in human serum samples are based on an indirect enzyme-linked immunosorbent assay (ELISA). Anti RSVPreF3 antibody concentration is given in geometric mean concentration (GMC) and is expressed in ELISA Laboratory Units per milliliter (ELU/mL). The assay cut-off is 25 ELU/mL.

  3. Number of Subjects With Any SAEs, up the End of Follow-up Study Period (Month 14) [ Time Frame: From Day 1 up to the end of follow-up period (Month 14) ]

    pIMDs are a subset of AEs that include autoimmune diseases and other inflammatory and/or neurologic disorders of interest which may or may not have an autoimmune etiology.

  5. Number of Subjects With Respiratory Tract Infection (RTI) Episodes Reported During RTI Surveillance [ Time Frame: During the RSV seasons from Day 1 to Month 14 ]
    The number of RTI cases is provided by group. Reported categories are "RSV+ RTI" (= RTI episode tested as RSV positive by quantitative reverse transcription polymerase chain reaction (qRT-PCR) on nasal/throat swab collected at assessment visit) and "RSV- RTI" (= RTI episode tested as RSV negative by qRT-PCR on nasal/throat swab collected at assessment visit).
