研究概览
简要总结
This protocol posting deals with objectives & outcome measures of the extension phase up to 48-50 months post booster vaccination, to assess long-term antibody persistence in children at around 30, 42 and 66 months of age, who received previously 4 doses of pneumococcal conjugate vaccine. The objectives & outcome measures of the primary phase are presented in a separate protocol posting (NCT number = 00307554). This Protocol posting has been updated in order to comply with the FDA AA (Sep 2007).
详细描述
This study consists in a serological follow-up study to evaluate persistence 12, 24 and 48 months after the booster vaccination study (107046). No study vaccines will be administered within this study.
