Safety Study of a Single Dose of Monovalent High-dose Inactivated Poliovirus Type 2 Vaccine (m-IPV2 HD) in Infants Early in Life

Summary

Phase II, observer-blind, randomized study on the safety, reactogenicity, immunogenicity and impact on intestinal shedding of a single dose of monovalent high-dose inactivated poliovirus type 2 vaccine (m-IPV2 HD) or a single dose of standard trivalent inactivated poliovirus vaccine (t-IPV) when given concomitantly with the third dose of bivalent oral poliovirus vaccine (b-OPV) to infants early in life
