Outcome Measures

Primary Outcomes (1)

  • The seroprotection rate of anti-diphtheria toxoid (DT) and anti-tetanus toxoid (TT) at 28 days after vaccination with the investigational products

    Seroprotection was defined as anti-DT and anti-TT antibody concentrations ≥ 0.1 IU/mL (ELISA)

    28 days after vaccination

Secondary Outcomes (2)

  • The geometric mean titer (GMT) of anti-DT and anti-TT at 28 days after vaccination with the investigational products

    28 days after vaccination

  • The boosting response for antitoxins of diphtheria and tetanus at 28 days after vaccination with the investigational product

    28 days after vaccination

Study Arms (2)

BR-TD-1001

EXPERIMENTAL

  • Those who have received immunoglobulin therapies or blood derived products within 3 months before screening, or are expected to receive them during the study period
  • Use of antipyretics/analgesics/nonsteroidal anti inflammatory drugs within 4 hours before administration of the investigational vaccine
  • Participation in other clinical studies within 28 days before screening
  • +1 more criteria
