US-licensed Combined Vaccine Against Tetanus & Diphtheria, Given With US-licensed Vaccine Against Meningococcal Disease
United States1,344 participantsStarted 2006-01-25
Plain-language summary
New immunization recommendations in the US include vaccination of adolescents against pertussis and meningococcal disease. The Advisory Committee on Immunization Practices of the Centers for Disease Control and Prevention recommends that Tdap (Tetanus Toxoid, Reduced Diphtheria Toxoid And Acellular Pertussis Vaccine Adsorbed) and MCV4 (Meningococcal conjugate vaccine against serotypes A, C, Y and W-135) vaccines be administered to adolescents at the same office visit if vaccination with both vaccines is indicated. Therefore, this study is designed to evaluate the safety and immunogenicity of a booster vaccination with Boostrix co-administered with Menactra as compared to the administration of either vaccine alone in healthy adolescents 11 - 18 years of age.

Inclusion Criteria:
* Healthy subjects as established by medical history and history-directed physical examination before entering into the study.
* Previously completed routine childhood vaccinations against diphtheria, tetanus and pertussis diseases according to the recommended vaccination schedule at the time.
* Females of childbearing potential at the time of study entry are required to have a negative pregnancy test prior to administration of the dose of vaccine and are required to be abstinent or use adequate contraceptive precautions for one month prior to vaccination. Subjects also are required to agree to continue such precautions for two months after vaccination.
Exclusion Criteria:
* Administration of a pre-school booster of DTP vaccine within the previous 5 years
* Administration of a diphteria-tetanus (Td) booster within the previous 5 years
* Previous vaccination against N. meningitidis
* Hypersensitivity to latex
* History of serious allergic reaction (e.g. anaphylaxis) following any other tetanus toxoid, diphteria toxoid or pertussis-containing vaccine or any component of the study vaccines
* History of encephalopathy (e.g. coma, decreased level of consciousness, prolonged seizures) within seven days of administration of a previous dose of pertussis vaccine taht is not attributable to another identifiable cause
* Progressive neurologic disorder, uncontrolled epilepsy or progressive encephalopathy: pertussis vaccine should not be administered to individuals …
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
