Brief Summary:
The purpose of the study is to compare the immunogenicity and safety of a booster dose of BoostrixTM administered in a new syringe presentation to that of BoostrixTM administered in the previous syringe presentation in healthy adolescents aged 10-15 years.

Condition or disease Intervention/treatment Phase
Diphtheria Tetanus Acellular Pertussis Biological: Boostrix TM (new syringe presentation) Biological: Boostrix TM (previous syringe presentation) Phase 4

Detailed Description:

The protocol has been updated following Protocol amendment 1 date 03 August 2011 leading to the update of the exclusion criteria to allow subjects in Mexico to receive the flu vaccine in accordance with the local standard of care.

The protocol has been updated following Protocol amendment 2 dated 14 December 2011 due to the recruitment constraints as a result of the DT/dTpa vaccination campaign in the countries. The inclusion and exclusion criteria were amended to allow the participation of those who have already received the 6th dose of the diphtheria, tetanus and/or pertussis containing vaccine.

    Booster response to the diphtheria and tetanus antigens, was defined as: for initially seronegative subjects (pre-vaccination concentration <0.1 IU/mL): antibody concentrations at least 4 times the cut-off (post-vaccination concentration ≥ 0.4 IU/mL); for initially seropositive subjects (pre-vaccination concentration ≥ 0.1 IU/mL): an increase in antibody concentrations of at least 4 times the pre-vaccination concentration.

  5. Number of Subjects With a Booster Response to Pertussis Toxoid (PT), Filamentous Haemagglutinin (FHA), Pertactin (PRN) Antigens. [ Time Frame: At Month 1 ]
    Booster response to the PT, FHA and PRN antigens, was defined as: for initially seronegative subjects: antibody concentrations at least 4 times the cut-off (post-vaccination concentration ≥ 20 EL.U/mL); for initially seropositive subjects with pre-vaccination concentration ≥ 5 EL.U/mL and < 20 EL.U/mL: an increase in antibody concentrations of at least 4 times the pre-vaccination concentration; and for initially seropositive subjects with pre-vaccination concentration ≥ 20 EL.U/mL: an increase in antibody concentrations of at least 2 times the pre-vaccination concentration.

  6. Number of Subjects With Any Solicited Local Symptoms [ Time Frame: Within 4 days (Days 0-3) post vaccination period ]
    Assessed solicited local symptoms were pain, redness and swelling. Any = occurrence of the symptom regardless of intensity grade.

  7. Number of Subjects With Unsolicited Adverse Events (AEs) [ Time Frame: Within 31 days (Days 0-30) post ]
    An unsolicited AE covers any untoward medical occurrence in a clinical investigation subject temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product and reported in addition to those solicited during the clinical study and any solicited symptom with onset outside the specified period of follow-up for solicited symptoms. Any was defined as the occurrence of any unsolicited AE regardless of intensity grade or relation to vaccination.

  8. Number of Subjects With Any Solicited General Symptoms [ Time Frame: Within 4 days (Days 0-3) post vaccination period ]
    Assessed solicited general symptoms were fatigue, temperature [defined as axillary temperature equal to or above 37.5 degrees Celsius (°C)], headache and gastrointestinal symptoms. Gastrointestinal symptoms included Nausea, Vomiting, Diarrhea and or Abdominal pain. Any = occurrence of the symptom regardless of intensity grade.

  9. Number of Subjects With Serious Adverse Events (SAEs) [ Time Frame: During the entire study period (Day 0 - Month 1) ]
    Serious adverse events (SAEs) assessed include medical occurrences that result in death, are life threatening, require hospitalization or prolongation of hospitalization or result in disability/incapacity.
