- Written informed consent obtained from the parent(s)/LAR(s) of the subject prior to performing any study specific procedure.
- A male or female child 9 months of age at the time of enrolment.
- Healthy subjects as established by medical history and clinical examination before entering into the study.
- Subjects born to mothers who were vaccinated in 116945 [DTPA (BOOSTRIX)-047] study and having completed their primary vaccination series as per protocol requirement in study 201330 [DTPA (BOOSTRIX)-048 PRI].
Exclusion Criteria:
- Child in care
- Concurrently participating in another clinical study, within three months prior to the booster vaccine dose and at any time during the present booster study, in which the subject has been or will be exposed to an investigational or a non-investigational vaccine/product (pharmaceutical product or device).
- Chronic administration (defined as more than 14 days in total) of immunosuppressants or other immune-modifying drugs during the period within six months prior to the booster vaccine dose. 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).
A vaccine not foreseen by the study protocol administered during the period starting from 30 days before the booster dose of study vaccine and ending 30 days after*, with the exception of inactivated influenza vaccine and other vaccines given as a part of the national/regional immunization 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 immunization 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 Product Information (PI) and according to the local governmental recommendations and provided a written approval of the Sponsor is obtained.
- Any confirmed or suspected immunosuppressive or immunodeficient condition, based on medical history and physical examination (no laboratory testing required).
- Major congenital defects.
- Serious chronic illness.
- Administration of immunoglobulins and/or any blood products during the period within three months before the booster dose of study vaccines or planned administration during the study period.
- Encephalopathy defined as an acute, severe central nervous system disorder occurring within 7 days following vaccination with Infanrix hexa and generally consisting of major alterations in consciousness, unresponsiveness, generalised or focal seizures that persist more than a few hours, with failure to recover within 24 hours.
- History of Hib, diphtheria, tetanus, pertussis, pneumococcal, poliovirus and hepatitis B diseases since the conclusion visit of study 201330 [DTPA (BOOSTRIX)-048 PRI].
- Previous booster vaccination against Hib, diphtheria, tetanus, pertussis, pneumococcus, hepatitis B and/or poliovirus since the conclusion visit of study 201330 [DTPA (BOOSTRIX)-048 PRI].
- History of any reaction or hypersensitivity likely to be exacerbated by any component of the vaccines (e.g: antigen, excipients).
- Hypersensitivity to latex.
- History of any neurological disorders or seizures.
- Any condition that in the judgment of the investigator would make intramuscular injection unsafe.
Acute disease and/or fever at the time of vaccination.
- Fever is defined as temperature ≥ 37.5°C /99.5°F for oral, axillary or tympanic route, or ≥ 38.0°C /100.4°F on 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.

Number of Subjects With an ASQ-3 Score (Ages & Stages Questionnaires, Third Edition) in the Black Zone
Time Frame: At 9 months of age, 18 months of age, and 9 or 18 months of age

Neurodevelopmental status was measured by ASQ-3 score scale [ASQ-3, 2016] in the black zone.
The ASQ-3 included a series of questions designed to assess 5 areas of development (communication, gross motor, fine motor, problem solving, and personal-social).
Any subject who scored below the cut-off i.e., a score more than 2 Standard Deviations (SDs) below the mean score for the U.S. reference group (i.e., black zone in the score chart) in any of the 5 domains of the ASQ-3 was to be referred to a developmental specialist for a formal neurodevelopmental assessment (using the Bayley Scale for Infant Development, Version III [BSID-III])
|
At 9 months of age, 18 months of age, and 9 or 18 months of age
|
Number of Subjects Referred for Formal Neurodevelopmental Evaluation Using BSID-III (Bayley Scale for Infant Development, Version III)
Time Frame: At 9 months of age, 18 months of age, and 9 or 18 months of age
|
Any subject who scored below the cut-off i.e., a score more than 2 Standard Deviations (SDs) below the mean score for the U.S. reference group (i.e., black zone in the score chart) in any of the 5 domains of the ASQ-3 was referred to a developmental specialist for a formal neurodevelopmental assessment (using the Bayley Scale for Infant Development, Version III BSID-III)
|
At 9 months of age, 18 months of age, and 9 or 18 months of age
|
Estimated Proportion of Infants With at Least One of the Indicators of Neurodevelopmental Impairment Using BSID-III (Bayley Scale for Infant Development, Version III)
Time Frame: At 9 months of age, 18 months of age, and 9 or 18 months of age
|
The estimated proportion (expressed in percentage) of infants with a BSID-III indicator of neurodevelopmental delay was based on ASQ-3 black zone indicator and subsequent BSID-III assessment using the following formula: 100 * (Number of subjects with ASQ-3 below cut off / Number of enrolled subjects with available results) * (Number of subjects with at least one indicator of neurodevelopmental delay using BSID III / Number of subjects referred for BSID III evaluation)
|
At 9 months of age, 18 months of age, and 9 or 18 months of age
