• Judged to be in good health on the basis of reported medical history and history-directed physical examination.
• Plans to remain in the study area for the length of the trial.
• The participant and a parent or legal guardian can read, write, and understand the documents and all are mentally competent to give assent and consent.
• If female, not known or suspected to be pregnant at the time of enrollment into the study and is not planning pregnancy during participation in this trial.

• Malignancy, allergy immunotherapy, or receiving immunosuppressive therapy (participants who are taking topical and inhaled steroids could be included in the study as would participants on a "short course" of oral steroids, -<7 days, as long as there are not two courses within the previous two weeks prior to vaccination).
• Receipt of any pertussis, diphtheria or tetanus-containing vaccines within the past 3 years.
• Any unstable significant underlying chronic disease, including (but not limited to) malignancy, cardiopulmonary disease, renal, endocrinologic, hematologic or hepatic dysfunction.
