Exclusion criteria
Exclusion criteria: 1. Anaphylaxis following the administration of vaccine 2. Any (clinical) condition that in the judgment of the investigator would make intramuscular injection unsafe and/or represents a contraindication to intramuscular vaccination and blood draws. 3. Any confirmed or suspected immunosuppressive or immunodeficient condition, including HIV infection. 4. Progressive, unstable or uncontrolled clinical conditions. 5. Hypersensitivity, including allergy, to any component of vaccines, medicinal products or medical equipment whose use is foreseen in this study. 6. Hypersensitivity to the active substances or to any of the excipients of the vaccine, including diphtheria toxoid (CRM197), or a life-threatening reaction after previous administration of a vaccine containing similar components. 7. Abnormal function of the immune system resulting from: - Clinical conditions. - Systemic administration of corticosteroids (Per os [PO]/ Intravenous [IV]/ Intramuscular [IM]) for more than 14 consecutive days within 90 days prior to informed consent, and until the Day 29 blood draw. - Administration of antineoplastic and immuno-modulating agents or radiotherapy within 90 days prior to informed consent, and until the Day 29 blood draw. 8. Received immunoglobulins or any blood products within 180 days prior to informed consent. 9. Received an investigational or non-registered medicinal product within 30 days prior to informed consent. 10. Any other clinical condition that, in the opinion of the investigator, might interfere with the results of the study or pose additional risk to the subject due to participation in the study. 11. History of any meningococcal vaccination. 12. Individuals who received any other vaccines within 7 days (for inactivated vaccines) or 14 days (for live vaccines) prior to enrolment in this study or who are planning to receive any vaccine within 28 days from the study vaccines*. * In case an emergency mass vaccination for an unforeseen public health threat (e.g.: a pandemic) is organised by the public health authorities, outside the routine immunization program, the time period described above can be reduced if necessary for that vaccine provided it is licensed and used according to its Summary of Product Characteristics (SmPC) or Prescribing Information and according to the local governmental recommendations and provided a written approval of the Sponsor is obtained. 13. Administration of long-acting immune-modifying drugs at any time during the study period (e.g. infliximab). 14. Concurrently participating in another clinical study, at any time during the study period, in which the subject has been or will be exposed to an investigational or a non-investigational vaccine/product. (pharmaceutical product or device). 15. Current or previous, confirmed or suspected disease caused by N. meningitidis. 16. Household contact with and/or intimate exposure to an individual with any laboratory confirmed N. meningitidis infection within 60 days prior to study vaccination. 17. Acute disease and/or fever within 3 days prior to study vaccination. Note: enrolment may be postponed/delayed until such transient circumstances have ended. - Fever is defined as body temperature = 38.0°C / 100.4°F. The preferred location for measuring temperature in this study will be the oral cavity. - Subjects with a minor illness (such as mild diarrhoea, mild upper respiratory infection) without fever may be enrolled at the discretion of the

| Main Objective: To demonstrate non-inferiority of the MenACWY liquid vaccine with approximately 30% Men A Free Saccharide (FS) to that of currently licensed MenACWY vaccine, as measured by the human serum bactericidal assay (hSBA) Geometric Mean Titers (GMTs) directed against N. meningitidis serogroup A at Day 29 after a single dose vaccination. Criterion to demonstrate non-inferiority: Non-inferiority will be concluded if the lower limit of the two-sided 95% confidence interval (CI) for the ratio of hSBA GMTs against serogroup A between the liquid for-mulation and the licensed formulation is greater than 0.5.;Secondary Objective: • To compare the immunogenicity of the investigational MenACWY liquid vaccine with approximately 30% Men A FS and the currently licensed MenACWY vaccine, as measured by: • hSBA GMTs directed against N. meningitidis serogroups C, W & Y at Day 29. • the percentage of subjects with a = 4-fold rise in post-vaccination hSBA titer for N. meningitidis serogroups A, C, W & Y at Day 29 compared to Day 1. • the percentage of subjects with hSBA titer =8 and = Lower Limit of Quantitation (LLOQ)* against N. meningitidis serogroups A, C, W & Y at Day 29. *To be assessed for each serogroup if the pre-defined LLOQ value for that serogroup is >8 • To assess the safety/reactogenicity of the investigational MenACWY liquid vaccine with approximately 30% Men A FS and the currently licensed MenACWY vaccine.;Primary end point(s): Human Serum Bactericidal Activity (hSBA) Geometric Mean Titers (GMTs) against N. meningitidis serogroup A for each vaccine group and between-groups ratios. ;Timepoint(s) of evaluation of this end point: At Day 29 | — |

| Secondary end point(s): 1. hSBA GMTs against each of the N.meningitidis serogroups A, C, W and Y for each vaccine group and between-groups ratios. 2. Within-group Geometric Mean Ratios (GMRs) of GMTs against each of the N.meningitidis serogroups A, C, W and Y. 3. Percentages of subjects with =4 fold rise in hSBA antibody titers for each of the N.meningitidis serogroups A, C,W and Y for each vaccine group and between-groups differences. 4. Percentages of subjects with hSBA titers =8 and =LLOQ against each of the N. meningitidis serogroups A, C, W and Y for each vaccine group and between-groups differences. 5. Number of subjects reporting any unsolicited adverse events (AEs) within 30 min after vaccination. 6. Number of subjects reporting solicited local and systemic AEs. 7. Number of subjects reporting other indicators of reactogenicity. 8. Number of subjects reporting any unsolicited AEs. 9.
