• Occurrence of any of the following adverse event after a previous administration of a DTP vaccine :

  • hypersensitivity reaction to any component of the vaccine,
  • encephalopathy of unknown aetiology occurring within 7 days following previous vaccination with pertussis-containing vaccine,
  • fever >= 40°C within 48 hours of vaccination not due to another identifiable cause,
  • collapse or shock-like state (hypotonic-hyporesponsiveness episode) within 48 hours of vaccination,
  • convulsions with or without fever, occurring within 3 days of vaccination.
• Acute disease at the time of enrolment.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: BOOSTRIX I GROUP; Subjects, who had received Boostrix™ vaccine in the primary study (263855/004), received one additional booster dose of Boostrix™ vaccine in this study, administered as an intramuscular injection into the deltoid region of the non-dominant arm.	Biological: Boostrix TM; Single booster dose of vaccine; Other Names: dTpa vaccine
Experimental: BOOSTRIX II GROUP; Subjects, who had received Wyeth's (formerly Lederle) combined adult diphtheria and tetanus vaccine and GSK Biologicals' acellular pertussis vaccine in the primary study (263855/004), received one booster dose of Boostrix™ vaccine in this study, administered as an intramuscular injection into the deltoid region of the non-dominant arm.	Biological: Boostrix TM; Single booster dose of vaccine; Other Names: dTpa vaccine

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Number of Subjects With Anti-diphtheria (Anti-DT) and Anti-tetanus Toxoids (Anti-TT) Antibody Concentrations Above the Cut-offs	The antibody concentrations cut-offs assessed were: equal to or above (≥) 0.1 international units per milliliter (IU/mL) and ≥ 1 IU/mL.	At Month 0
Number of Subjects With Anti-diphtheria (Anti-DT) and Anti-tetanus Toxoids (Anti-TT) Antibody Concentrations Above the Cut-offs	The antibody concentrations cut-offs assessed were: equal to or above (≥) 0.1 international units per milliliter (IU/mL) and ≥ 1 IU/mL.	At Month 1

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Anti-diphtheria (Anti-DT) and Anti-tetanus Toxoids (Anti-TT) Antibody Concentrations	Concentrations are presented as international units per millilitre (IU/mL).	At Month 0 (PRE) and Month 1 (POST)
Number of Seropositive Subjects for Anti-pertussis Toxoid (Anti-PT), Anti-filamentous Haemagglutinin (Anti-FHA) and Anti-pertactin (Anti-PRN)	A seropositive subject was defined as a subject with anti-PT, anti-FHA and anti-PRN antibody concentrations ≥ 5 ELISA unit per milli-liter (EL.U/ml)	At Month 0 (PRE) and Month 1 (POST)
Anti-pertussis Toxoid (Anti-PT), Anti-filamentous Haemagglutinin (Anti-FHA) and Anti-pertactin (Anti-PRN) Antibody Concentrations	Concentrations are presented as geometric mean concentrations (GMCs), expressed in ELISA units per millilitre (EL.U/mL).	At Month 0 (PRE) and Month 1 (POST)
Number of Subjects With Booster Response to Anti-pertussis Toxoid (Anti-PT), Anti-filamentous Haemagglutinin (Anti-FHA) and Anti-pertactin (Anti-PRN)	Booster response was defined as appearance of antibodies in subjects who were seronegative at the pre-vaccination time point (i.e. with concentrations < 5 El.U/mL) or at least 2-fold increase of prevaccination antibody concentrations in subjects who were seropositive at the pre-vaccination time point (i.e. with concentrations ≥5 El.U/mL.	At Month 1
Number of Subjects With Any and Grade 3 Solicited Local Symptoms	Assessed solicited local symptoms were pain, redness and swelling. Any = occurrence of the symptom regardless of intensity grade. Grade 3 pain = pain that prevented normal activity. Grade 3 redness/swelling = redness/swelling spreading beyond 50 millimeters (mm) of injection site.	During the 4-day (Day 0-3) follow-up period after booster vaccination
Number of Subjects With Any, Grade 3 and Related Solicited General Symptoms	Assessed solicited general symptoms were fatigue, fever [defined as axillary temperature equal to or above 37.5 degrees Celsius (°C)], headache and gastrointestinal symptoms. Any = occurrence of the symptom regardless of intensity grade. Grade 3 symptom = symptom that prevented normal activity. Grade 3 fever = fever > 39.0 °C. Related = symptom assessed by the investigator as related to the vaccination.	During the 4-day (Day 0-3) follow-up period after booster vaccination
Number of Subjects With Unsolicited Adverse Events (AEs)	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.	During the 31-day (Day 0-30) follow-up period after booster vaccination
Number of Subjects With Serious Adverse Events (SAEs)	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.	For safety assessment Boostrix I Group and Boostrix II Group were pooled (Pooled Group)
