Clinical Trial Summary

This is a follow-up of the primary series vaccination schedule in Study A3L24 (NCT01177722). The objectives are:

• To describe the antibody persistence to any antigen contained in the investigational DTaP-IPV-Hep B-PRP-T vaccine and Infanrix hexa™ prior to the booster dose

• To describe the safety and immunogenicity of the booster dose of either DTaP-IPV-Hep B-PRP-T or Infanrix hexa™ vaccine.

• To describe the immunogenicity of a booster dose of Prevenar™ given at 12 to 24 months.

Description:

All participants who completed trial A3L24 (NCT01177722) will be recruited to participate in this trial. Those who received DTaP-IPV-Hep B-PRP-T combined vaccine will be randomized to receive either a booster dose of DTaP-IPV-Hep B-PRP-T or Infanrix hexa™ vaccine.

Those who received Infanrix hexa™ will receive a booster dose of DTaP-IPV-Hep B-PRP-T combined vaccine. All participants will receive a booster dose of Prevenar™ concomitantly.

Outcome

Primary	Summary of Diphtheria and Tetanus Post Primary Series Antibodies, Persistence and Booster Response Following Vaccination With Either DTaP-IPV Hep B-PRP T Vaccine or Infanrix Hexa Vaccine	Anti-Diphtheria (D) antibodies were measured by a toxin neutralization test. Anti-Tetanus (T) antibodies were measured by enzyme-linked immunosorbent assay (ELISA). Antibody persistence for anti-Diphtheria and anti-Tetanus antibodies was defined as titers =0.01 IU/mL and =0.1 IU/mL before the booster dose at Day 0. Booster response to Diphtheria and Tetanus was defined as antibody titers =0.01 IU/mL and =0.1 IU/mL at Day 30 post-booster vaccination.; Day 140 = Primary series; Day 0 = Pre-booster; and Day 30 = Post-booster titers	Day 140 (Primary series) and Day 0 (Pre-booster)	No
