Persistence of Antibodies in Adolescents and Adults 15 to 23 Years Who Received One Dose of Menactra® or Menomune®

The study is designed to evaluate the persistence of bactericidal antibodies in subjects aged 15 to 23 years (not yet 24 years) who had been vaccinated five years previously in Study MTA02 and did not participate in Study MTA19 (NCT 00777790). In addition, the kinetics of the antibody response will be evaluated in a subset of these participants who will receive a booster dose of Menactra® vaccine. This will be compared to aged matched control subjects who have not been previously vaccinated with a meningococcal vaccine or had documented meningitis disease who will also receive a dose of Menactra® vaccine.

• Meningitis
• Meningococcal Infection

• Experimental: Menactra® Vaccine Group 1
  Participants had previously received a dose of Menactra® vaccine in Study MTA02,did not participate in Study MTA19 (NCT 00777790). They provided a pre-vaccination blood sample on Day 0, received one booster dose of Menactra® vaccine on Day 0 and provided 3 additional blood samples on Day 3, Day 7, and Day 28 post-vaccination.
  Intervention: Biological: Meningococcal Polysaccharide Diphtheria Toxoid Conjugate
• Experimental: Menactra® Vaccine Group 2
  Participants had previously received a dose of Menactra® vaccine in Study MTA02,did not participate in Study MTA19 (NCT 00777790). They provided a pre-vaccination blood sample on Day 0, received one booster dose of Menactra® vaccine on Day 0 and provided 3 additional blood samples on Day 5, Day 14, and Day 28 post-vaccination
  Intervention: Biological: Meningococcal Polysaccharide Diphtheria Toxoid Conjugate
• Active Comparator: Meningococcal Vaccine-naive Group 3
  Participants have never received Meningococcal vaccine and provided one blood sample pre-vaccination on Day 0, received a dose of Menactra® vaccine on Day 0, and provided 3 additional blood samples on Day 3, Day 7, and Day 28 post-vaccination.
  Intervention: Biological: Meningococcal Polysaccharide Diphtheria Toxoid Conjugate
• Active Comparator: Meningococcal Vaccine-naive Group 4
  Participants have never received Meningococcal vaccine and provided one blood sample pre-vaccination on Day 0, received a dose of Menactra® vaccine on Day 0, and provided 3 additional blood samples on Day 5, Day 14, and Day 28 post-vaccination.
  Intervention: Biological: Meningococcal Polysaccharide Diphtheria Toxoid Conjugate

Inclusion Criteria:

• Subject is healthy, as determined by medical history.
• Subject is between the ages of 15 and 23 years (not yet 24 years).
• For subjects who participated in Study MTA02, subject previously received one dose of Menactra® vaccine or Menomune®-A/C/Y/W-135 vaccine.
• Did not participate in Study MTA19 (a subset of subjects from Study MTA02 who had been recruited for a follow-up challenge study)
• Subject or parent/legal guardian has signed an Institutional Review Board (IRB)-approved informed consent form and subject has signed an IRB-approved assent form.
• Before recruitment for the second part of the study, subjects should be thoroughly screened to ensure that they are able to comply with protocol specifications
• A negative urine pregnancy test is required for menstruating female subjects.

Exclusion Criteria:

• History of documented invasive meningococcal disease.
• Received any other meningococcal vaccine
• Received any vaccine (other than desensitization therapy for allergies) in the 28-day period prior to enrollment
• Scheduled to receive any vaccination in the 28-day period after enrollment
• Received systemic antibiotic therapy within the 72 hours prior to collection of a blood sample
