Evaluation of Antibody Persistence at 3.5 and 4.5 Years of Age in Healthy Children After Primary Series and Booster Vaccination With Investigational (DTaP-IPV-Hep B-PRP~T) or Infanrix Hexa™ Vaccines in Latin America
This is a follow-up of the primary series vaccination schedule in Study A3L24 (NCT01177722) and booster vaccination in Study A3L27 (NCT01444781). Study Objective: * To describe the long-term antibody persistence at 3.5 and 4.5 years of age following a 3-dose primary series vaccination of either DTaP-IPV-Hep B-PRP-T+Prevenar™ (PCV7) +Rotarix™ or Infanrix hexa™+Prevenar™ (PCV7) +Rotarix™ vaccination at 2, 4, 6 months of age and a booster vaccination of DTaP-IPV-Hep B-PRP-T+Prevenar™ (PCV7) or Infanrix hexa™+Prevenar™ (PCV7) at 12 to 24 months of age. Observational Objectives: * To describe the long-term antibody persistence by group and by stratification on the age at inclusion of the A3L27 booster study. * To describe the effect of one additional oral dose of stand alone poliovirus isotypes 1, 2 and 3 vaccine\* on the antibody persistence immune response for poliovirus isotypes (4 vs 5 doses of poliovirus administered).
