To describe the antibody levels for tetanus, diphtheria and pertussis at 1 year, 3 years, 5 years and 10 years after vaccination with Tdap Vaccine. |
|
E.2.2 | Secondary objectives of the trial |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
Participation in original Study Td9805 and the receipt of Tdap. |
|
E.4 | Principal exclusion criteria |
1. Pregnancy or planning a pregnancy during the study period.
2. Known or suspected primary disease of the immune system (conditions suspected of having an immunologic component such as autoimmune diseases (rheumatoid arthritis or inflammatory bowel disease) will not be excluded unless they meet exclusion criterion 3 or are sufficiently clinically active to meet exclusion criterion 5).
3. Malignancy or receiving immunosuppressive therapy (e.g. daily systemic prednisone 1 mg/kg would be excluded. Participants who were taking topical and inhaled steroids could be included in the study as could participants on a “short course” of oral steroids, 5-7 days, as long as there were not two courses within the previous two week period.)
4. Receipt of any pertussis, diphtheria or tetanus containing vaccines within the previous 5 years.
5. Any significant underlying chronic disease, including malignancy, cardiopulmonary disease, renal or hepatic dysfunction.
6. Known impairment of neurologic function or seizure disorder of any etiology.
7. Personal history of physician diagnosed or laboratory confirmed pertussis disease within the previous 2 years.
8. Receipt of blood products or immunoglobulin within the previous 3 months.
9. Known or suspected allergy to any of the vaccines intended for use in the study.
10. Receipt of any vaccine within 2 weeks of receiving a study vaccine.
11. Daily use of non-steroidal anti-inflammatory drugs (NSAIDS).
