Study will evaluate the persistence of antibodies approximately three years after an initial dose of Menactra® vaccine in toddlers who participated in study MTA26 (NCT00643916) and age-matched Menactra naive participants.
Objectives:
- To assess the persistence of antibody responses three years after one or two doses of Menactra® vaccine in subjects who participated in study MTA26.
- To describe the antibody responses to a single dose of Menactra® vaccine in subjects who had previously received one or two doses of Menactra® vaccine and in Menactra® vaccine-naïve subjects.
- To describe the safety profile of a single dose of Menactra® vaccine in subjects.

- Percentage of Participants With Serum Meningococcal Serogroups A, C, Y, and W-135 Bactericidal Antibody Titers ≥ 1:4 and ≥ 1:8 Before and Following Vaccination With Menactra® [ Time Frame: Day 0 (pre-vaccination) and Day 30 post-vaccination ]Antibody titers to meningococcal serogroups A, C, Y, and W-135 were measured by serum bactericidal assay using human complement (SBA-HC). Bactericidal antibody persistence to meningococcal serogroups was defined as as pre-vaccination titers of ≥1:4 and ≥1:8. Booster response to a single Menactra vaccine dose was defined as antibody titers of ≥1:4 and ≥1:8 30 days post-booster vaccination.
- Geometric Mean Antibody Titers to Meningococcal Serogroups A, C, Y, and W-135 Before and Following Vaccination With Menactra®. [ Time Frame: Day 0 (pre-vaccination) and Day 30 post-vaccination ]Antibody titers to meningococcal serogroups A, C, Y, and W-135 were measured by serum bactericidal assay using human complement (SBA-HC).
- Percentage of Participants Experiencing Solicited Injection-Site or Systemic Reactions Following Vaccination With Menactra® [ Time Frame: Day 0 up to Day 7 post-vaccination ]Solicited injection-site: Pain, Erythema, and Swelling. Solicited systemic reactions: Fever (Temperature), Headache, Vomiting, Drowsiness, Anorexia, Irritability, Arthralgia, and Diarrhea. Grade 3 Solicited Injection-site: Pain - Incapacitating, unable to perform usual activities; Erythema and Swelling - ≥2.0 in. Grade 3 Solicited systemic: Fever (Temperature) ->39.0˚C (>102.2˚F); Headache - Prevents daily activities; Vomiting - ≥3 episodes per 24 hours; Drowsiness - Disabling, dozing off or falling asleep while engaged in usual activities; Anorexia - Skips ≥3 meals; Irritability - >3 hours duration; Arthralgia - Unwilling to move due to pain; and Diarrhea - ≥ 5 episodes per 24 hours.

Accepts Healthy Volunteers: | Yes |
Inclusion Criteria :
- Subjects received one or two doses of Menactra® vaccine in study MTA26 and provided a blood sample after the last dose received
- At 3 to < 6 years of age and were never vaccinated against meningococcal disease (with either the study vaccine or another vaccine).
- Informed consent form signed and dated by the parent(s) or another legally acceptable representative.
- Subject and parent/legal guardian able to attend all scheduled visits and comply with all study procedures.
Exclusion Criteria :
- Participation in the active (i.e., treatment) portion of another clinical trial investigating a vaccine, drug, medical device, or a medical procedure in the 4 weeks preceding the first study vaccination
- Planned participation in another clinical trial during the present trial period.
- Known or suspected congenital or acquired immunodeficiency, immunosuppressive therapy such as anti-cancer chemotherapy or radiation therapy within the preceding 6 months, or long-term systemic corticosteroids therapy.
- Known or suspected systemic hypersensitivity to any of the vaccine components, or history of a life-threatening reaction to the study vaccine or to a product containing any of the substances present in the study vaccine.
- Chronic illness at a stage that could interfere with trial conduct or completion, in the opinion of the investigator.
- Received blood or blood-derived products in the past 3 months.
- Received any vaccine (other than desensitization therapy for allergies or influenza vaccine within 2 weeks before vaccination) in the 4 weeks preceding the first study vaccination.
- Planned receipt of any vaccine within the 4 weeks following the study vaccination.
- Known human immunodeficiency virus (HIV), hepatitis B surface antigen (HBs antigen), or hepatitis C seropositivity.
- History of invasive meningococcal infection (confirmed either clinically, serologically, or microbiologically).
- Thrombocytopenia, coagulation disorder, or anticoagulant use in the 3 weeks preceding inclusion contraindicating intramuscular (IM) vaccination.
- Anticipated to receive oral or injected antibiotic therapy within the 72 hours prior to any of the trial blood draws.
- Personal or family history of Guillain-Barré Syndrome (GBS).
