Brief summary
The aim of the study is to generate additional safety and immunogenicity data to support the registration of the product in Japan. Primary objectives: * To demonstrate the non-inferiority of SP306 versus DT (DT 0.1mL) vaccine in terms of diphtheria and tetanus booster response rate (proportion of subjects with booster responses) and seroprotection rate (percentage of subjects with antitoxin concentrations ≥0.1 IU/mL) at 28 days (window 28-35 days) after one injection in Japanese adolescents 11-12 years of age. * To evaluate the immune response of SP306 against the pertussis antigens PT and FHA in terms of booster response rate (proportion of subjects with booster responses) at 28 days (window 28-35 days) after one injection in Japanese adolescents 11-12 years of age. Secondary objectives: * To further evaluate the immune response of the study vaccines against diphtheria, tetanus and pertussis antigens. * To assess the safety of the study vaccines after one injection in Japanese adolescents 11-12 years of age.
Detailed description
Study participants will receive either a single dose of SP306 vaccine intramuscularly or a dose of DT vaccine subcutaneously. They will be monitored after vaccination for immediate adverse events (AEs) solicited injection site and systemic reactions and unsolicited AEs including serious adverse events throughout the study period, approximately 28 days (+7 days).

Percentage of Participation With Seroprotection to Diphtheria and Tetanus Antigens Before Vaccination With Either SP306 or DT Vaccine
Seroprotection was defined as the proportion of participants with pre-vaccination with diphtheria and tetanus antitoxin concentration ≥ 0.1 IU/mL. Diphtheria antitoxin concentration was assayed by the toxin neutralization test; Tetanus antitoxin concentration was assayed by the enzyme-linked immunosorbent assay (ELISA) method.
Time frame: Pre-vaccination (Day 0)
Population: Seroprotection was assessed in the per-protocol population
