• Written informed consent obtained from parents/guardian of the subject and written informed assent obtained from the subject if the subject is less than legal age, or written informed consent obtained from the subject if the subject has achieved legal age. The legal age will be determined according to local regulations in each participating country.
• Healthy subjects as established by medical history and clinical examination before entering into the study.
• Female subjects of non-childbearing potential may be enrolled in the study.
• Non-childbearing potential is defined as pre-menarche, current tubal ligation, hysterectomy, ovariectomy or post-menopause.

• History of encephalopathy within seven days of administration of a previous pertussis antigen-containing vaccine that is not attributable to another identifiable cause.
• Persons who experienced an Arthus-type hypersensitivity reaction following a prior dose of tetanus-toxoid containing vaccine should not receive Boostrix unless at least 10 years have elapsed since the last dose of tetanus-toxoid containing vaccine.
• Previous vaccination with a tetanus-toxoid containing vaccine within the previous five years.
• Temperature of ≥ 40.5°C (105°F) within 48 hours of receipt of a previous dose of DTP vaccine (diphtheria-tetanus-whole cell pertussis [DTPw] and/or diphtheria-tetanus-acellular pertussis [DTaP]), not due to another identifiable cause.
• Collapse or shock-like state within 48 hours of receipt of a previous dose of DTP vaccine.
• Seizures with or without fever within three days of a previous dose of DTP vaccine.
• Any confirmed or suspected immunosuppressive or immunodeficient condition, including human immunodeficiency virus (HIV) infection, based on medical history and history directed physical examination.
