Outcome Measures

Primary Outcomes (1)

  • Number of Participants With First Occurrence of Reverse Transcriptase Polymerase Chain Reaction (RT-PCR)-Confirmed Respiratory Syncytial Virus (RSV) Mediated Lower Respiratory Tract Disease (LRTD)

    Number of participants with first occurrence of RT-PCR-confirmed RSV mediated LRTD according to protocol defined criteria were reported. A participant was considered to have RT-PCR-confirmed RSV-mediated LRTD if the following criteria were met: new onset or worsening from baseline of 3 or more of the symptoms as captured on the respiratory infection intensity and impact questionnaire (RiiQ, version 2) at the same assessment time point: cough, short of breath, coughing up phlegm (sputum), and wheezing and confirmation of RSV by RT-PCR in one or more of the nasal swabs, or in the sputum sample. RiiQ symptom scale was a 13-item questionnaire rated on a 4-point scale. Each symptom was rated on a scale of 0 to 3 where 0=None, 1=Mild, 2=Moderate, and 3=Severe. Higher scores indicated greater severity. The total LRTD symptom score was calculated as the mean of the 4 lower respiratory scores (cough, short of breath, coughing up phlegm \[sputum\] and wheezing).

    From Baseline (Day 1) up to 12 months

Secondary Outcomes (13)

  • Number of Participants With First Occurrence of Any RT-PCR-Confirmed RSV-mediated Acute Respiratory Infection (ARI)

    From Baseline (Day 1) up to 12 months

  • Number of Participants With First Occurrence of RT-PCR-Confirmed RSV Mediated LRTD During the Second Year

    From Month 12 up to Month 24

  • Number of Participants With First Occurrence of Any RT-PCR-Confirmed RSV Mediated ARI During the Second Year

    From Month 12 up to Month 24

  • Number of Participants With First Occurrence of Predefined Clinically Relevant Disease Associated With RT-PCR-Confirmed RSV-Mediated ARI Over the Whole Study

    Baseline (Day 1) up to 24 months

  • Number of Participants With Serious Adverse Events (SAEs)

    28 days post vaccination on Day 1 (Day 29); First year follow-up (from Day 29 up to 6 months, that is, up to Day 154)

  • +8 more secondary outcomes
