             entering into the study.

          -  Female subjects of non-childbearing potential may be enrolled in the study.

          -  Female subjects of childbearing potential may be enrolled in the study, if the
             subject:

               -  Has practiced adequate contraception for 30 days prior to study vaccination, and

               -  Has a negative pregnancy test on the day of study vaccination, and

             non-investigational vaccine/ product.

          -  Any medical condition that in the judgment of the investigator would make
             intramuscular injection unsafe.

          -  Planned administration/ administration of a vaccine not foreseen by the study protocol
             within the period starting 30 days before and ending 30 days after study vaccination,

             of the study vaccines.

          -  History of severe allergic reaction after a previous dose of any tetanus toxoid,
             diphtheria toxoid, or pertussis antigen-containing vaccine or to any component of
             Boostrix.

          -  History of encephalopathy of unknown aetiology occurring within 7 days following a
             previous vaccination with pertussis-containing vaccine.

          -  History of any neurological disorders or seizures

          -  History of transient thrombocytopenia or neurological complications following a
             previous vaccination against diphtheria and/ or tetanus.

             Inhaled and topical steroids are allowed.

          -  Administration of immunoglobulins and/ or any blood products within the 3 months prior
             to study vaccination, or planned administration during the study period.
