Study to Evaluate a 13-valent Pneumococcal Conjugate Vaccine in Infants.

Phase 3

Completed

• Conditions: Vaccines, Pneumococcal
• Interventions: Biological: 13-valent pneumococcal conjugate vaccine; Biological: 7-valent pneumococcal conjugate vaccine

• Registration Number: NCT00366340
• Lead Sponsor: Wyeth is now a wholly owned subsidiary of Pfizer

Brief Summary

The purpose of this study is to assess the safety, tolerability and immunogenicity of a 13-valent pneumococcal conjugate (13vPnC) vaccine compared to 7-valent pneumococcal conjugate (Prevenar/Prevenar®, 7vPnC), when given concomitantly with Infanrix hexa at 2, 3, 4, months (infant series) and at 11-12 months of age (toddler dose) in Germany.
