Descriptive Information
Brief Title  ICMJE A Study to Assess the Antibody Response of Healthy Chinese Children Who Have Been Vaccinated Previously With 4-doses of Prevenar (a Pneumococcal Vaccine) as Babies and Toddlers
Official Title  ICMJE A Phase 4, Open-label Study to Evaluate Persistence of the Antibody Response Elicited by Prevenar in Healthy Children in China Who Have Been Previously Immunized With a 4-dose Series of a Pneumococcal Conjugate Vaccine During Infancy in Study 0887x-101518
