This study is designed to assess the immunogenicity and safety of tetanus toxoid, reduced diphtheria toxoid and acellular pertussis vaccine (ADACEL®, Tdap vaccine) as a booster dose in adolescents in Japan.
Primary Objective:
- To assess the immunogenicity of Tdap (SP306) when administered as a single dose in Japanese adolescents
Secondary Objective:
- To assess the safety of Tdap vaccine when administered as a single dose in Japanese adolescents.

- Percentage of Participants With Seroprotection Against Diphtheria and Tetanus Antigens Following Vaccination With ADACEL® [ Time Frame: Day 28 post-vaccination ]Seroprotection was defined as the percentage of participants with antibody concentration of ≥0.1 IU/mL, post-vaccination.
- Percentage of Participants With Booster Response to Diphtheria and Tetanus Antigens Following Vaccination With ADACEL® [ Time Frame: Day 28 post-vaccination ]
Diphtheria booster response was defined as a ≥ 4-fold rise in pre- to post-vaccination antitoxin concentration in a subject with a pre-vaccination antitoxin concentration ≤ 2.56 IU/mL; or a ≥ 2-fold rise in a subject with a pre-vaccination antitoxin concentration > 2.56 IU/mL.
Tetanus booster response was defined as a ≥ 4-fold rise in pre- to post- vaccination antitoxin concentration in a subject with a pre-vaccination antitoxin concentration ≤ 2.7 IU/mL; or a ≥ 2-fold rise in a subject with a pre-vaccination antitoxin concentration > 2.7 IU/mL.
- Percentage of Participants With Booster Response to Pertussis Antigens, Pertussis Toxoid and Filamentous Hemagglutinin Following Vaccination With ADACEL® [ Time Frame: Day 28 post-vaccination ]Booster responses were defined as: Pre-vaccination antibody concentrations less than the lower limit of quantitation (LLOQ) and a post-vaccination levels ≥ 4x LLOQ; or Pre-vaccination antibody concentrations ≥ LLOQ but < 4x LLOQ, and a 4-fold rise (i.e., post-/pre-vaccination ≥ 4), or Pre-vaccination antibody concentrations ≥ 4x LLOQ and a 2-fold rise (i.e., post-/pre-vaccination ≥ 2)
- Percentage of Participants With Seroprotection Against Diphtheria and Tetanus Antigens Pre-vaccination With ADACEL® [ Time Frame: Day 0 pre-vaccination ]Seroprotection was defined as the percentage of participants with antibody concentration of ≥0.1 IU/mL.
- Percentage of Participants With Seroprotection Against Diphtheria and Tetanus Pre-vaccination and Post-vaccination With ADACEL® [ Time Frame: Day 0 (pre-vaccination) and day 28 post-vaccination ]Seroprotection was defined as the percentage of participants with antibody concentration of ≥0.01 IU/mL.
- Percentage of Participants With Seroprotection Against Diphtheria and Tetanus Antigens Pre-vaccination and Post-vaccination With ADACEL® [ Time Frame: Day 0 (pre-vaccination) and day 28 post-vaccination ]Seroprotection was defined as the percentage of participants with antibody concentration of ≥1.0 IU/mL.
- Geometric Mean Concentrations With Respect to Diphtheria and Tetanus Antibodies Pre- and Post-vaccination With ADACEL® [ Time Frame: Day 0 (pre-vaccination) and Day 28 post-vaccination ]
- Geometric Mean Concentrations With Respect to Pertussis Antibodies Pre- and Post-vaccination With ADACEL® [ Time Frame: Day 0 (pre-vaccination) and Day 28 post-vaccination ]
- Percentage of Participants With Booster Response to Pertussis Antigens, Pertactin and Fimbriae Following Vaccination With ADACEL® [ Time Frame: Day 28 post-vaccination ]Booster responses were defined as: Pre-vaccination antibody concentrations less than the lower limit of quantitation (LLOQ) and a post-vaccination levels ≥ 4x LLOQ; or Pre-vaccination antibody concentrations ≥ LLOQ but < 4x LLOQ, and a 4-fold rise (i.e., post-/pre-vaccination ≥ 4), or Pre-vaccination antibody concentrations ≥ 4x LLOQ and a 2-fold rise (i.e., post-/pre-vaccination ≥ 2)
- Number of Participants Reporting Solicited Injection-site and Systemic Reactions Following Vaccination With ADACEL® [ Time Frame: Day 0 up to Day 7 post-vaccination ]
Solicited injection-site reactions: Pain, Redness, and Swelling. Grade 3: Pain, Significant, prevents daily activity; Redness and Swelling, >100 mm.
Solicited systemic reactions: Fever (Temperature); Headache, Malaise, and Myalgia. Grade 3: Fever, ≥ 39°C; Headache, Malaise and Myalgia, Significant, prevents daily activity.
