•A male or female between 10 and 15 years of age (from and including the 10th birthday up to but excluding the 16th birthday) at the time of booster vaccination.
•Prior to protocol amendment 2, subjects who have previously received 5 doses of DTP (w/a) as part of primary and booster vaccination, in line with local recommendations.
•After protocol amendment 2, subjects who have previously received 6 doses of either DT(P) (w/a)/ dTpa vaccine as part of primary and booster vaccination, in line with local recommendations.
•Healthy subjects as determined by the investigator based on medical history and clinical examination before entering into the study.
•Written informed consent to be obtained before study entry from the parent(s)/LAR(s) of the subject.
•Written informed assent to be obtained from the subject in addition to the informed consent signed by the parent(s)/LAR(s), if required by local regulations.
•Female subjects of non-childbearing potential may be enrolled in the study.
-Non-childbearing potential is defined as pre-menarche, current tubal ligation, hysterectomy or ovariectomy.
•Female subjects of childbearing potential may be enrolled in the study, if the subject:
-has a negative pregnancy test on the day of vaccination; and
-if sexually active, has practiced adequate contraception for 30 days prior to vaccination, and has agreed to continue adequate contraception during the entire treatment period and for 2 months after booster vaccination.

Exclusion Criteria

•Child in care.
•Use of any investigational or non-registered product (drug or vaccine) other than the study vaccine within 30 days preceding the booster dose of study vaccine, or planned use during the study period.
•Chronic administration (defined as more than 14 days in total) of immunosuppressants or other immune-modifying drugs within six months prior to the booster dose. For corticosteroids, this will mean prednisone < 20 mg/day or equivalent, inhaled and topical steroids are allowed.
•Planned administration/administration of a vaccine not foreseen by the study protocol within 30 days of the booster dose of vaccine with the exception of influenza vaccine which is allowed up to 7 days before the study vaccine dose, or planned in the period = 7 days after the study vaccine dose.
•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).
•A history of previous or intercurrent diphtheria, tetanus or pertussis disease.
•A history of vaccination against these diseases since the 5th or the 6th dose of DT(P)/dT(pa). For subjects who have received the 6th dose of the diphtheria, tetanus and/or pertussis containing vaccine, the interval between the last DT(P)/dT(pa) vaccination and the administration of the study vaccine should be at least 18 months .
•Occurrence of any of the following adverse event after a previous administration of a Boostrix vaccine :
-known hypersensitivity to any component of the vaccine, or have shown signs of hypersensitivity after previous administration of diphtheria, tetanus or pertussis vaccines,
-encephalopathy of unknown aetiology occurring within 7 days following previous vaccination with pertussis-containing vaccine,
-transient thrombocytopenia or neurological complications following an earlier immunisation against diphtheria and/or tetanus.
•Any confirmed or suspected immunosuppressive or immunodeficient condition, based on medical history and physical examination (no laboratory testing required).
•History of any reaction or hypersensitivity likely to be exacerbated by any component of the vaccine (including latex).
•Administration of immunoglobulins and/or any blood products within the 3 months preceding the first dose of study vaccine or planned administration during the study period.
•Acute disease and/or fever at the time of enrolment.
-Fever is defined as temperature = 37.5°C on oral, axillary or tympanic setting, or = 38.0°C on rectal setting. The preferred route for recording tempera-ture in this study will be oral or axillary.
-Subjects with a minor illness (such as mild diarrhea, mild upper respiratory infection), without fever, may be enrolled at the discretion of the investigator.
•Pregnant or lactating female.
•Female planning to become pregnant or planning to discontinue contraceptive precautions, if applicable.
