years of age).
- have provided written assent (≥7-<18 years)
- have provided written informed consent (≥18 to 75 years of age).
2. who the investigator believes that they or their parents/legal representatives can and
will comply with the requirements of the protocol (e.g., completion of the Diary Card,
return for follow-up visit).
3. who are in good health as determined by

E.4 | Principal 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 enrolment.
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 enrolment 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 enrolment 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 enrolment significant acute infection
(for example requiring systemic antibiotic treatment or antiviral therapy) or have
experienced fever (defined as body temperature 38°C) within 3 days prior to
enrolment.
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 enrolment (any
systemic corticosteroid administered for more than 5 days, or in a daily dose > 1
mg/kg/day prednisone or equivalent during any of 28 days prior to enrolment, or
cancer chemotherapy)
- receipt of immunostimulants
- receipt of parenteral immunoglobulin preparation, blood products, and/or plasma
derivatives within 90 days prior to enrolment 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. |

≥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. |
