• 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).

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 investigator.

18. Received systemic antibiotic treatment within 3 days prior to study vaccination or blood draw.

19. Study personnel as an immediate family or household member.

20. Pregnant or lactating women.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Adjusted Human Serum Bactericidal Activity (hSBA) Geometric Mean Titers (GMTs) Against N. Meningitidis Serogroup A for Each Vaccine Group, and Between-group Ratios	hSBA titers against N.meningitidis serogroup A were calculated in terms of GMTs adjusted for pre-vaccination titer.	At Day 29
Secondary	hSBA GMTs Against Each of the N.Meningitidis Serogroups A, C, W and Y for Each Vaccine Group, and Between-group Ratios	hSBA titers were calculated in terms of GMTs, at Day 1 and Day 29, against each of the N. meningitidis serogroups A, C, W and Y.	At Day 1 and Day 29
Secondary	Within-group Geometric Mean Ratios (GMRs) Against Each of the N.Meningitidis Serogroups A, C, W and Y	Within-group ratios of hSBA GMTs against each of the N.meningitidis serogroups A, C, W and Y at Day 29 compared to Day 1.	At Day 29
Secondary	Percentages of Subjects With a =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-group Differences	The percentages of subjects with a = 4-fold rise in post-vaccination hSBA (at Day 29 compared to Day 1) and associated 2-sided 95% Clopper-Pearson CIs were computed by group and for each N. meningitidis serogroups A, C, W and Y. A 4-fold rise in the hSBA titers is defined as: for individuals, whose pre-vaccination titers are < the LOD (limit of detection), the post-vaccination titers must be = 4-fold the LOD or = the LLOQ (lower of limit of quantitation) whichever is greater; for individuals, whose pre-vaccination titers are = the LOD and = the LLOQ, the post-vaccination titers must be at least four times the LLOQ; for individuals whose pre-vaccination titers are > the LLOQ, the post-vaccination titers must be at least four times the pre-vaccination	At Day 29
Secondary	Percentages of Subjects With hSBA Titers =8 Against Each of the N. Meningitidis Serogroups A, C, W and Y for Each Vaccine Group, and Between-group Differences	For each vaccine group the percentage of subjects with hSBA titer =8, and its associated two-sided 95% Clopper-Pearson CIs were computed for each of the N. meningitidis serogroups A, C, W and Y.	At Day 1 and Day 29
Secondary	Percentages of Subjects With hSBA Titers =LLOQ Against Each of the N. Meningitidis Serogroups A, C, W and Y for Each Vaccine Group, and Between-group Differences	For each vaccine group the percentage of subjects with hSBA titer =LLOQ, and its associated two-sided 95% Clopper-Pearson CIs were computed for each of the N. meningitidis serogroups A, C, W and Y.	At Day 1 and Day 29
Secondary	Number of Subjects Reported With Solicited Local and Systemic AEs	Number of subjects with solicited local and systemic AEs during the 7-days period (including the day of vaccination) after the vaccination.	From Day 1 (6 hours) to Day 7 after vaccination

From Day 1 to Day 29 after vaccination
Secondary	Number of Subjects Reported With AEs Leading to Withdrawal, Medically Attended AEs and Serious Adverse Events (SAEs)	Medically attended AEs are defined as events for which the subject received medical attention defined as hospitalization, an emergency room visit, or a visit to or from medical personnel (medical doctor) for any reason. Any medically attended AE(s) is occurrence of any medically attended AE(s) regardless of intensity grade or relation to vaccination.
