What researchers measure

Primary outcomes

  1. Participants With Antibody Responses to Tetanus and Diphtheria Components Following Vaccination With Either GC3111 or Boostrix® Vaccine

    Time frame: Day 0 (pre-vaccination) to Day 28 (post-vaccination)

  2. Percentage of Participants Achieving Predefined Antibody Level for Diphtheria, Tetanus, and Acellular Pertussis Antigens

    Time frame: 28 days after Vaccination

  3. Geometric Mean Concentrations (GMC) for Diphtheria, Tetanus and Acellular Pertussis Antigens

    Time frame: 28 days after Vaccination

  4. Geometric Mean Ratio (GMR) of post-vaccination versus pre-vaccination antibody concentrations against Diphtheria, Tetanus and Acellular Pertussis

    Time frame: Day 0 (pre-vaccination) to Day 28 (post-vaccination)

Secondary outcomes

  1. Participants Reporting Immediate Solicited Adverse Events Following Vaccination With Either GC3111 or Boostrix® Vaccine

    Time frame: Up to 30 minutes post-vaccination
