This study is a Phase III, randomized, single-blind, placebo-controlled, multi-center study to be conducted in healthy infants and toddlers aged 6 months + 2 weeks for Cohort 1 and 12 months ± 2 weeks for Cohort 2. The primary objective of the study will be to assess non-inferiority of the respiratory syncytial virus toddler and infant (RSVt) vaccine antibody response when administered concomitantly with routine pediatric vaccines at 6 months of age (Diphtheria and Tetanus Toxoids and Acellular Pertussis, Inactivated Poliovirus, Haemophilus b Conjugate and Hepatitis B Vaccine [Vaxelis® or Pentacel® and Recombivax HB®] Prevnar 20®, and RotaTeq®), and 12 months of age (M-M-R II, VARIVAX, and Prevnar 20 or per local country recommendations) compared to when administered non-concomitantly.
The study duration is approximately 9 months for each participant. - Cohort 1: Visits at 6, 7, and 8 and 9 months of age for both groups with visit at 10 months of age for Group 2 only - Cohort 2: Visits at 12, 13, 14 and 15 months of age for both groups with visit at 16 months of age for Group 4 only - Routine pediatric vaccines (authorized auxiliary medicinal products (AxMP) will be administered at 6 months in Cohort 1 and 12 months of age in Cohort 2, as per Advisory Committee on Immunization Practice (ACIP) or local country recommendations. ;
