- Background: To assess the immunogenicity and safety of a fully liquid, ready-to-use hexavalent DTaP-IPV-HB-PRP-T vaccine when administered in a 2 + 1 schedule at 3, 5 and 11-12 months of age.Methods: Phase III, randomized, active-controlled, observer-blind, multi-center study. Infants were randomized to receive DTaP-IPV-HB-PRP-T (N = 275) or a licensed control hexavalent vaccine (DTaP-IPV-HB//PRPNT: N = 275), both given in coadministration with Prevenar 13. Serum was analyzed for immune responses to all vaccine antigens. Noninferiority of DTaP-IPV-HB-PRP-T to the control vaccine was tested at completion of the primary series using predefined seroprotection (SP) rate and vaccine response (VR) rates. Safety was assessed using parental reports.Results: Noninferiority of DTaP-IPV-HB-PRP-T to the control vaccine was demonstrated postdose 3 for each antigen, and the SP (for D, T, poliovirus 1, 2 and 3, hepatitis B and polyribosylribitol phosphate) and VR rates (for pertussis toxin and filamentous hemagglutinin) were high in each group. SP rates for D, T, polio 1, 2, 3 and VR rates for pertussis toxin and filamentous hemagglutinin were similar in each group. For hepatitis B, SP rate was slightly higher for DTaP-IPV-HB//PRP similar to T (99.6%) than DTaP-IPV-HB-PRP-T (96.4%), and for PRP, SP rate was higher for DTaP-IPV-HB-PRP-T (93.5%) than DTaP-IPV-HB//PRP similar to T (85.2%). For Prevenar 13, the SP rate was high for each serotype and similar for both groups. All vaccines were well tolerated.Conclusions: These study findings confirm the safety and immunogenicity and thus the suitability of this fully liquid hexavalent vaccine for administration in a 2 + 1 schedule.
