Immunogenicity and safety of fully liquid DTaP₅-IPV-Hib compared with DTaP₃-IPV/Hib when both coadministered with a heptavalent pneumococcal conjugate vaccine (PCV7) at 2, 3, 4, and 12 to 18 months of age: a phase III, single-blind, randomised, controlled, multicentre study.

This study compared immunogenicity and safety of DTaP(5)-IPV-Hib to DTaP(3)-IPV/Hib coadministered with PCV7 at 2, 3, and 4 months (primary series) and a fourth-dose booster at 12-18 months of age. Seroprotection rates for DTaP(5)-IPV-Hib were high (noninferior to DTaP(3)-IPV/Hib for the primary series) for antigens common to both vaccines and PCV7 antigens. Geometric mean concentration (GMC) for Hib antibodies were higher in the DTaP(5)-IPV-Hib group than the DTaP(3)-IPV/Hib group after the primary series and booster dose; GMCs or titers for other antigens were generally similar between groups after the primary series and booster dose. Safety profiles were similar between groups.
