Study Summary

The overall aim of the study is to corroborate that a schedule consisting of 3 doses of Pentacel™ and a 4th dose of DAPTACEL® and ActHIB® or 4 doses of Pentacel™ or 4 doses of Quadracel and ActHIB® is as safe and immunogenic as a standard of care schedule based on 3 doses of the licensed-equivalent vaccines DAPTACEL®, Vero cell derived Inactivated Poliovirus vaccine (IPOL®), and ActHIB® and a 4th dose of DAPTACEL® and ActHIB®.

Primary Outcome

Vaccine response was calculated as a pre-dose 1 titer ≤ Lower Limit of Quantitation (LLOQ) and post-dose 3 titer \> LLOQ; or a pre-dose 1 titer \> LLOQ and post-dose 3 titer ≥ pre-dose 1 titer.

Interventions

  • BIOLOGICAL DAPTACEL®. (DTaP), IPOL®., and ActHIB®.
  • BIOLOGICAL Pentacel®: DTaP-IPV/Hib combined
