- Subjects who the investigator believes that their parents/guardians can and will comply with the requirements of the protocol.
- A male or female in their third year of life at the time of the study initiation for the subjects who enter the study at Visit 1. The subjects who enter the study at Visit 2 should be in their fourth year of life at the time of the study initiation.
- Previous administration of a booster dose of Hib or meningococcal serogroup C except booster study vaccines during the study Hib-MenC-TT-010 BST:DTPA-HBV-IPV-097. Subjects who received a 4th dose of Meningitec™ should be included in the study.
- History of H. influenzae type b, meningococcal serogroup C diseases.
- A male or female in their third year of life at the time of the study initiation for the subjects who enter the study at Visit 1. The subjects who enter the study at Visit 2 should be in their fourth year of life at the time of the study initiation.
- Written informed consent obtained from the parent or guardian of the subject.
- Healthy subjects as established by medical history and clinical examination before entering into the study.
- Having completed the booster vaccination study Hib-MenC-TT-010 BST:DTPA-HBV-IPV-097 (NCT=00323050).
- Subjects who are part of the Meningitec™ control group and who were not enrolled at Visit 1 can be enrolled at Visit 2 if they have completed the booster vaccination study Hib-MenC-TT-010 BST:DTPA-HBV-IPV-097 (NCT=00323050) and if they have received a fourth dose of Meningitec™ in their second year of life, after the booster study Hib-MenC-TT-010 BST:DTPA-HBV-IPV-097 (NCT=00323050)
Subjects who the investigator believes that their parents/guardians can and will comply with the requirements of the protocol.
- History of H. influenzae type b, meningococcal serogroup C diseases.
Previous administration of a booster dose of Hib or meningococcal serogroup C except booster study vaccines during the study Hib-MenC-TT-010 BST:DTPA-HBV-IPV-097. Subjects who received a 4th dose of Meningitec™ should be included in the study.
