Exclusion Criteria: Individuals not eligible to be enrolled in the study are those: 1. who are unwilling or unable to give written informed assent or consent to participate in the study. 2. who are perceived to be unreliable or unavailable for the duration of the study period. 3. who had a previous or suspected disease caused by N. meningitidis. 4. who had household contact with and/or intimate exposure to an individual with culture-proven N. meningitidis infection within 60 days prior to enrollment. 5. who have previously been immunized with a meningococcal vaccine. 6. who have received any investigational or non-registered product (drug or vaccine)within 28 days prior to enrollment or who expect to receive an investigational drug or vaccine prior to the completion of the study. 7. who have received any vaccines within 14 days (for inactivated vaccines) or 28 days (for live vaccines) prior to enrollment in this study or who are planning to receive any vaccine within 30 days from the study vaccines. (Exception: Influenza vaccine may be administered up to 15 days prior to study vaccination and at least 15 days after study vaccination) 8. who have experienced within the 7 days prior to enrollment significant acute infection (for example requiring systemic antibiotic treatment or antiviral therapy) or have experienced fever (defined as body temperature greater than or equal to 38°C) within 3 days prior to enrollment. 9. who have any serious acute, chronic or progressive disease (e.g., any history of neoplasm, cancer, diabetes, cardiac disease, autoimmune disease, HIV infection or AIDS, or blood dyscrasias, with signs of cardiac or renal failure or severe malnutrition). 10. who have epilepsy or any progressive neurological disease. 11. who have a history of any anaphylaxis, serious vaccine reactions, or allergy to any vaccine components. 12. who have a known or suspected impairment/alteration of immune function, either congenital or acquired or resulting from (for example): * receipt of immunosuppressive therapy within 28 days prior to enrollment (any systemic corticosteroid administered for more than 5 days, or in a daily dose greater than 1 mg/kg/day prednisone or equivalent during any of 28 days prior to enrollment, or cancer chemotherapy) * receipt of immunostimulants * receipt of parenteral immunoglobulin preparation, blood products, and/or plasma derivatives within 90 days prior to enrollment and for the full length of the study. 13. who are known to have a bleeding diathesis, or any condition that may be associated with a prolonged bleeding time. 14. who have any condition that, in the opinion of the investigator, might interfere with the evaluation of the study objectives.

Outcomes

Primary Outcomes

Percentages of Subjects With Human Serum Bactericidal Assay (hSBA) Seroresponse Against N.Meningitidis Serogroup A.

The immunogenicity of a single injection of MenACWY-CRM vaccine is assessed in terms of percentage of subjects with hSBA seroresponse directed against N.meningitidis serogroup A. Seroresponse is defined as: * For subjects with a pre-vaccination hSBA titer \<1:4, a postvaccination hSBA titer≥1:8 * For subjects with a pre-vaccination hSBA titer ≥1:4, an increase in hSBA titer of at least four times the pre-vaccination titer.

Time frame: Day 29 (1 month post vaccination)
