| E.2 Objective of the trial |
| E.2.1 | Main objective of the trial |
Co-primary objectives In subjects primed in the previous primary vaccination study 217744/097: One month after booster vaccination with a Hib-MenC conjugate vaccine, to evaluate the non-inferiority of the Hib component (anti-PRP >/= 1 mcg/ml) in toddlers aged 13-14 months and primed in infancy with 3 doses of Hib-MenC + DTPa-IPV-HBV or 2 doses of NeisVac-C + DTPa-(HBV)-IPV/Hib compared with infants primed with 3 doses of Meningitec and DTPa-HBV-IPV/Hib and boosted with DTPa-HBV-IPV/Hib. In the same subjects, to evaluate the immunogenicity in terms of the Men C component of the booster vaccine (SBA-MenC titer >/= 1:128).
|
|
| E.2.2 | Secondary objectives of the trial |
To evaluate: The non-inferiority of the Hib-MenC booster versus the control group (anti-PRP >/= 1 mcg/ml) and the immunogenicity (SBA-Men C >/= 1:128). The persistence of Hib, MenC and tetanus antibodies after primary vaccination (13-14 months of age). The persistence to diphtheria, hepatitis B, polio and pertussis antibodies in 50% of subjects. The Hib, MenC and tetanus immune responses in all subjects induced by the booster dose. Safety and reactogenicity of the booster dose.

| E.3 | Principal inclusion criteria |
Subjects who the investigator believes that their parents/guardians can and will comply with the requirements of the protocol (e.g., completion of the diary cards, return for follow-up visits) should be enrolled in the study. A male or female between, and including, 13 and 14 months of age at the time of booster vaccination. Written informed consent obtained from the parent or guardian of the subject. Free of obvious health problems as established by medical history and clinical examination before entering into the study. Having participated in the primary vaccination study 217744/097
|
|
| E.4 | Principal exclusion criteria |
Use of any investigational or non-registered product (drug or vaccine) other than the study vaccine(s) within 30 days preceding the booster vaccine, or planned use during the study period. Chronic administration (defined as more than 14 days) of immunosuppressants or other immune-modifying drugs within six months prior to the first vaccine dose. (For corticosteroids, this will mean prednisone, or equivalent, >/= 0.5 mg/kg/day. Inhaled and topical steroids are allowed.) Planned administration/ administration of a vaccine not foreseen by the study protocol within 30 days of the booster vaccine. Previous vaccination against diphtheria, tetanus, pertussis, hepatitis B, polio, H. influenzae type b (Hib) and/or meningococcal serogroup C disease except if within the framework of study 217744/097. History of diphtheria, tetanus, pertussis, hepatitis B, polio, Hib and/or meningococcal serogroup C disease. Known exposure to diphtheria, tetanus, pertussis, hepatitis B, polio, Hib and/or meningococcal serogroup C disease within the last 3 months. Any confirmed or suspected immunosuppressive or immunodeficient condition, including human immunodeficiency virus (HIV) infection. A family history of congenital or hereditary immunodeficiency. History of allergic disease or reactions likely to be exacerbated by any component of the vaccine. Major congenital defects or serious chronic illness. History of any neurologic disorders or seizures including febrile seizures (at least 2 events) in infancy. Acute disease at the time of enrolment. (Acute disease is defined as the presence of a moderate or severe illness with or without fever. All vaccines can be administered to persons with a minor illness such as diarrhea, mild upper respiratory infection with or without low-grade febrile illness, i.e., Oral temperature <37.5°C / Axillary temperature <37.5°C / Rectal temperature <38°C. Administration of immunoglobulins and/or any blood products within the three months preceding the first dose of study vaccine or planned administration during the study period.

| E.5.1 | Primary end point(s) |
One month after the booster vaccination: In all subjects Anti-PRP antibody concentration >/=1µg/ml
In subjects boosted with the Hib-MenC vaccine SBA-MenC titre >/= 1:128
