Brief Summary:
The purpose of this study is to provide critical information on the safety, reactogenicity and immunogenicity profile of the investigational recombinant chimpanzee adenovirus Type 155-vectored RSV (ChAd155-RSV) vaccine in infants likely to be unexposed to RSV and will assess a single lower dose and a higher two dose regimen, before moving to future studies. This study will also assess if there is a risk of 'vaccine-induced enhanced RSV disease' after vaccination of these infants with the ChAd155-RSV vaccine.

Primary Outcome Measures :
  1. Number of Subjects With Any Solicited Local Adverse Events (AEs) During a 7-day Follow-up Period After the First Vaccination (Administered at Day 1) [ Time Frame: During a 7-day follow-up period after the first vaccination (administered at Day 1) ]
    Assessed solicited local AEs are erythema, pain and swelling at injection site. Any = occurrence of the adverse event regardless of intensity grade. Any redness and swelling = adverse event reported with a surface diameter greater than 0 millimeters. Analysis of this outcome measure were reported for the RSV1D pooled, RSV2D pooled, active comparators pooled and placebo groups separately to compare the expected adverse events observed from routine pediatric vaccines (active comparators) with the investigational RSV vaccine. Placebo was not pooled with active comparators as no significant difference was expected in AEs when placebo was pooled with active comparators. As pre-specified in the protocol, the choice of active comparator or placebo was based on each participating country's standard of care.

  2. Number of Subjects With Any Solicited Local Adverse Events (AEs) During a 7-day Follow-up Period After the Second Vaccination (Administered at Day 31) [ Time Frame: During a 7-day follow-up period after the second vaccination (administered at Day 31) ]
    Analysis of this outcome measure were reported for the RSV1D pooled, RSV2D pooled, active comparators pooled and placebo groups separately to compare the expected adverse events observed from routine pediatric vaccines (active comparators) with the investigational RSV vaccine. Placebo was not pooled with active comparators as no significant difference was expected in AEs when placebo was pooled with active comparators. As pre-specified in the protocol, the choice of active comparator or placebo was based on each participating country's standard of care.

  3. Number of Subjects With Any Solicited General AEs During a 7-day Follow-up Period After the First Vaccination (Administered at Day 1) [ Time Frame: During a 7-day follow-up period after the first vaccination (administered at Day 1) ]

Any = occurrence of the adverse event regardless of intensity grade or relation to study vaccination. Analysis of this outcome measure were reported for the RSV1D pooled, RSV2D pooled, each of the active comparators and placebo groups separately as the study interest was to investigate solicited AEs during the follow-up period of RSV vaccine administration, compared to placebo and routine pediatric vaccines, especially comparing to the rates of Bexsero-related fever. As pre-specified in the protocol, the choice of active comparator or placebo was based on each participating country's standard of care.

  4. Number of Subjects With Any Solicited General AEs During a 7-day Follow-up Period After the Second Vaccination (Administered at Day 31) [ Time Frame: During a 7-day follow-up period after the second vaccination (administered at Day 31) ]
    Analysis of this outcome measure were reported for the RSV1D pooled, RSV2D pooled, each of the active comparators and placebo groups separately as the study interest was to investigate solicited AEs during the follow-up period of RSV vaccine administration, compared to placebo and routine pediatric vaccines, especially comparing to the rates of Bexsero-related fever. As pre-specified in the protocol, the choice of active comparator or placebo was based on each participating country's standard of care.

  5. Number of Subjects With Any Unsolicited AEs [ Time Frame: During a 30-day follow-up period across the 2 vaccinations administered at Day 1 and Day 31 ]

Unsolicited AEs are 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 study vaccination. Analysis of this outcome measure were reported for the RSV1D pooled, RSV2D pooled, and comparator_placebo pooled groups as data collection was based on different standard of care provided at participating countries rather than randomization to each of the individual groups. According to the pre-specified analysis plan, data collected for participant flow, baseline characteristics and adverse events reporting were not analyzed for the individual groups.

  6. Number of Subjects With Any Serious Adverse Events (SAEs) From Day 1 up to Day 61 [ Time Frame: From Day 1 up to Day 61 ]
    Assessed serious adverse events (SAEs) include medical occurrences that resulted in death, were life-threatening, required hospitalization or prolongation of hospitalization or resulted in disability/incapacity. Any = occurrence of SAE regardless of intensity grade or relation to study vaccination. Analysis of this outcome measure were reported for the RSV1D pooled, RSV2D pooled, and comparator_placebo pooled groups as data collection was based on different standard of care provided at participating countries rather than randomization to each of theindividual groups.
