Persistence of Antibodies at 3, 4 and 6 Years of Age After Vaccination With Meningococcal, Pneumococcal and Hib Vaccines

Summary

This protocol posting deals with objectives \& outcome measures of an extension phase when subjects are aged 3, 4 and 6 years of age. The objectives \& outcome measures of the primary phase are presented in a separate protocol posting (NCT number = NCT00334334). The objectives \& outcome measures of the booster phase are presented in a separate protocol posting (NCT number = NCT00463437). The purpose of this study is to evaluate the persistence of pneumococcal, meningococcal serogroup C, Hib and Hepatits B antibodies after booster vaccination, when the subjects are aged 3, 4 and 6 years. No vaccine will be administered during this persistence phase of the study.
