This study is intended to support the registration of IMOVAX Polio in China.

The primary objective of this Pase III trial is to compare IMOVAX Polio to the current Chinese standard of care (OPV) that is administered following a schedule of 2-3-4 months. The objective is to demonstrate that after the 3 doses primary series, in terms of seroprotection rates, IMOVAX Polio is not inferior to OPV. The safety of IPV will be assessed after each IPV dose.
