About this study

The main objectives of this study are to : * 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.
