Eligibility criteria:

        Inclusion Criteria:

          -  Known or suspected impairment of immunologic function.

          -  Febrile illness within the last 72 hours or an oral temperature ≥100.4°F (≥38°C) at
             the time of inclusion.

          -  History of documented tetanus, diphtheria or pertussis disease within the preceding 5
             years.

          -  Known or suspected receipt of a tetanus-, diphtheria- or pertussis-containing vaccine
             since participation in Study Td501, Td502, or Td505. (Receipt of Menactra vaccine at
             any time prior to the present study is permitted, subject to the next exclusion
             criterion).

          -  Received any vaccine, other than influenza vaccine, in the 28-day period prior to
             enrollment or scheduled to receive any vaccine, other than influenza vaccine, in the

             enrollment

          -  Administration of immune globulin or other blood products within the last three
             months, or injected or oral corticosteroids or other immunomodulator therapy within
             six weeks of the study vaccine. Individuals on a tapering dose schedule of oral
             steroids lasting less than 7 days may be included in the trial as long as they have
             not received more than one course within the last two weeks prior to enrollment.
