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])

- 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

Key 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.

Summary
Brief summary
The purpose of this study is to assess the immunogenicity and safety of the Infanrix hexa
booster dose given at 11-18 months of age to infants who received primary vaccination at 6-14
weeks. All infants in this booster study were born to pregnant women who participated in the
