Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
* evaluate the safety and tolerability of trivalent novel oral poliovirus vaccines (tnOPV) in healthy adults, young children, and neonates, relative to those receiving control vaccines;
* evaluate the safety and tolerability of combined novel oral poliovirus vaccine type 1 (nOPV1) + novel oral poliovirus vaccine type 2 (nOPV2) in neonates, relative to those receiving the bivalent (types 1 and 3) oral poliovirus vaccine (bOPV) control.
* compare type-specific cumulative seroconversion rates of poliovirus neutralizing antibody (NAb) titers, among all tnOPV dose combinations, following 4 vaccinations in healthy neonates;
* evaluate the type-specific cumulative seroconversion rate of poliovirus NAb titers among healthy neonates following 4 doses of combined nOPV1+nOPV2.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The study population will include healthy adults (≥18 to ≤45 years old) who have previously completed their full routine polio immunization series, healthy young children (≥1 to \<5 years old) who have completed their full routine polio immunization series and healthy neonates (day of birth+3 days), who have not received any polio vaccination.
Enrollment in this study will be staggered into two stages and three age-descending cohorts.
Stage 1 will consist of an age-descension/dose escalation approach from adults to young children (Cohorts 1 and 2). Enrollment will begin with Cohort 1, in which 100 adults will be randomly allocated in a 1:1 ratio to Groups 1 and 2. Following a Protocol Safety Review Team (PSRT) review of the study Day 8 safety data (i.e. safety data reported up to 7 days post-vaccination #1, collected at Visit 2) of the adults in Cohort 1, and the absence of any safety concerns, 200 young children in Cohort 2 will be randomly allocated in a 1:1:1:1 ratio to Groups 3, 4, 5, and 6, respectively.
After the completion of enrollment of Cohort 2, the study will move into Stage 2. In addition to a PSRT review of Day 8 safety data of the young children in Cohort 2, there are two triggers of data from other studies to initiate the enrollment into Cohort 3:
* Absence of safety concerns upon the safety data reviews occurring at least 8 days after receipt of the first dose of 107.5 CCID50 nOPV1 or 107.5 CCID50 nOPV3 by the first 60 IPV-vaccinated infants enrolled in each of the Phase 2 monovalent trials CVIA 093 and CVIA 101, respectively (the first 45 nOPV:15 mOPV participants randomized per dose pair).
* Favorable immunogenicity data (homotypic anti-polio serum neutralizing antibody titers) from the Phase 2 monovalent nOPV1 study (CVIA 093) in IPV-vaccinated infants, and the Phase 2 monovalent nOPV3 study (CVIA 101) in young children.
Stage 2 will consist of dose exploration in neonates (Cohort 3). In Cohort 3, Groups 7-14, 2100 neonates will be randomly allocated in a 3:3:3:3:3:3:2:1 ratio, respectively.
