• Extended administration (defined as more than 14 days in total) of immunosuppressants or other immune-modifying drugs since birth. For corticosteroids, this will mean prednisone >= 0.5 mg/kg/day, or equivalent. Inhaled and topical steroids are allowed.

• Planned administration/ administration of a vaccine not foreseen by the study protocol during the period starting 30 days before the first dose of vaccine(s) until 30 days after the last dose of vaccine(s) (i.e. booster dose), with the exception of rotavirus vaccine which can be administered at any time during the study, according to the national immunisation recommendations. MMR(V) vaccine, if recommended in national immunisation programs, can be given after the last blood sampling time point i.e. after Visit 6. Seasonal or pandemic influenza vaccine can be given at any time during the study, and according to the Summary of Product Characteristics and national recommendations.

• Concurrently participating in another clinical study, at any time during the study period, in which the subject has been or will be exposed to an investigational or a non-investigational product (pharmaceutical product or device).

• Previous vaccination against diphtheria, tetanus, pertussis, polio, hepatitis B, Haemophilus influenzae type b, Streptococcus pneumoniae, Neisseria meningitidis serogroups A, C, W-135 or Y with the exception of vaccines where the first dose may be given within the first two weeks of life according to the national recommendations (for example hepatitis B and BCG).

• History of, or intercurrent, diphtheria, tetanus, pertussis, polio, hepatitis B, Haemophilus influenzae type b disease, pneumococcal and/or meningococcal disease.

• Any confirmed or suspected immunosuppressive or immunodeficient condition, based on medical history and physical examination (no laboratory testing required).

• Family history of congenital or hereditary immunodeficiency.

• History of any reaction or hypersensitivity likely to be exacerbated by any component of the vaccine(s).

• Major congenital defects or serious chronic illness.

• History of any neurologic disorders or seizures (history of a single, simple febrile seizure is permitted).

• Acute disease and/or fever at the time of enrolment. (Fever is defined as temperature = 37.5°C (99.5°F) on oral, axillary or tympanic setting, or = 38.0°C (100.4°F) on rectal setting).

(Subjects with a minor illness (such as mild diarrhoea, mild upper respiratory infection) without fever may, be enrolled at the discretion of the investigator).

• Administration of immunoglobulins and/ or any blood products since birth or planned administration during the study period.
