Original Secondary Outcome Measures  ICMJE
 (submitted: August 31, 2010)
  • The proportion of subjects achieving a serotype specific IgG concentration ≥ 0.35 μg/mL measured 1 month after the toddler dose for each of the pneumococcal serotypes for each group and group 1 sub-group. [ Time Frame: Visit 6 (13 months) ]
  • Fold rise in antibody concentration from the pretoddler dose to 1 month after the toddler dose for each subject. [ Time Frame: Visit 5 (12 months) to Visit 6 (13 months) ]
  • Persistence of antibody response induced by 13vPnC for each serotype and for each group (and subgroup), 1 month after the infant series, before toddler dose, 1 month after the toddler dose, 1 year after the toddler dose, and 2 years after the toddler. [ Time Frame: Baseline to visit 8 (36 months) ]

Brief Title  ICMJE Study Evaluating a 13-valent Pneumococcal Conjugate Vaccine in Preterm Compared to Term Infants.
Official Title  ICMJE A Phase 4, Open-label Trial Describing The Safety, Tolerability, And Immunogenicity Of The 13 Valent Pneumococcal Conjugate Vaccine In Preterm Compared To Term Infants
Brief Summary The purpose of this study is to describe the safety, tolerability, and immunogenicity of a 2,3,4 and 12 month schedule of the 13-valent pneumococcal conjugate vaccine when given to preterm infants with concomitant vaccines, compared to infants born at term.There will be a follow-up phase to assess the persistence of the antibody response at 24 and 36 months of age.
