Eligibility Criteria:

For corticosteroids, this will mean prednisone ≥0.5mg/kg/day, or equivalent. Inhaled and topical steroids are allowed.~* Administration of long-acting immune-modifying drugs at any time during the study period (e.g. infliximab).~* Administration of any chronic drug therapy to be continued during the study period.~* A vaccine not foreseen by the study protocol administered during the period starting from 30 days before each dose of vaccine and ending 30 days after\*, with the exception of inactivated influenza vaccine and other vaccines given as a part of the national/regional immunisation schedule, that are allowed at any time during the study period.~  * In case an emergency mass vaccination for an unforeseen public health threat (e.g.: a pandemic) is organised by the public health authorities, outside the routine immunisation program, the time period described above can be reduced if necessary for that vaccine provided it is licensed and used according to its SPC or package insert (PI) and according to the local governmental recommendations and provided a written approval of the Sponsor is obtained.~* 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 vaccine/product (pharmaceutical product or device).~* Previous vaccination against Hib, diphtheria, tetanus, pertussis, pneumococcus, and/or poliovirus since birth.~* History of Hib, diphtheria, tetanus, pertussis, pneumococcal, poliovirus and hepatitis B diseases.~* Any confirmed or suspected immunosuppressive or immunodeficient condition including severe combined immunodeficiency disease (SCID), 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.~* Major congenital defects~* Serious chronic illness.~* History of any neurological disorders or seizures.~* Acute disease and/or fever at the time of enrolment.~  * Fever is defined as temperature ≥37.5°C/99.5°F for oral, axillary or tympanic route, or ≥38.0°C/100.4°F for rectal route.~ * 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 during the period starting at birth before the first dose of study vaccines or planned administration during the study period.~* Hypersensitivity to latex.

Study Arms:
- dTpa Group (Type: EXPERIMENTAL): This group will consist of infants born to mothers belonging to the dTpa Group in study 116945 \[DTPA (BOOSTRIX)-047\] i.e. who received a single dose of BoostrixTM during pregnancy and a dose of placebo immediately post-delivery. All infants in this group will receive Infanrix hexaTM co-administered with Prevenar 13®.
- Control Group (Type: ACTIVE_COMPARATOR): This group will consist of infants born to mothers belonging to the Control group in study 116945 \[DTPA (BOOSTRIX)-047\], i.e. who received a single dose of placebo during pregnancy and a dose of BoostrixTM immediately post-delivery. All infants in this group will receive Infanrix hexaTM co-administered with Prevenar 13®.
