Intervention model description: The study will be conducted in 4 stages, sequentially:

* Stage 2; adults and adolescents from the EU and the US, equally randomized to 11 vaccine groups
* Stage 3: toddlers from the EU, equally randomized to 6 vaccine groups
* Stage 4: infants from the EU, equally randomized to 6 vaccine groups
Primary purpose: TREATMENT

Brief summary: Primary Objective:

* To describe the safety profile of the SP MenB vaccine formulations and the 2 licensed MenB comparator vaccines in healthy adults, adolescents, toddlers and infants, when administered alone (Stages 1-4) or concomitantly with MenQuadfiTM (MenACYW conjugate vaccine) (for Stages 2-4 only), and with age-appropriated routine pediatric vaccines (for Stages 3-4 only)

  1. To describe the safety profile of the SP MenB vaccine formulations, Bexsero Vaccine and Trumenba Vaccine in healthy adults, and adolescents;
  2. To describe the safety profile of the SP MenB vaccine formulations and Bexsero Vaccine in toddlers and infants;
  3. To describe the safety profile of the SP MenB vaccine formulations,

     * when administered alone
     * when administered with MenQuadfiTM (MenACYW conjugate vaccine)
     * when administered with routine infant immunizations
* To describe the immune response to the SP MenB vaccine formulations and the 2 licensed MenB comparator vaccines after the last dose of primary vaccination in healthy adults, adolescents, toddlers and infants, when administered alone, or concomitantly with MenQuadfi Vaccine or other routine vaccines, as measured by the serum bactericidal assay using human complement (hSBA) in the primary panel of MenB strains by Stage, by age group and by vaccine schedule

Secondary Objective:

* To describe the immune response to the SP MenB vaccine formulations and the 2 licensed MenB comparator vaccines at each timepoint in healthy adults, adolescents, toddlers and infants, when administered alone or concomitantly with MenQuadfi Vaccine or other routine vaccines as measured by hSBA in the primary panel of MenB strains by Stage by age group and by vaccine schedule
* To describe the immune response (breadth of coverage) in the secondary panel of MenB strains in participants (adults and adolescents) in Stage 1 and 2 after the last dose of the primary series in each group
* To describe the persistence of immune response following primary series at D366, and immune response 1 month after a booster dose of the SP MenB vaccine given 1-year post-dose 1 (at D366) in a subset of adults and adolescents in Stage 2 who received SP MenB vaccine formulations, Bexsero Vaccine or Trumenba Vaccine as measured by hSBA in the primary panel of MenB strains by age group
* To describe the immune response against meningococcal serogroups A, C, W and Y measured with hSBA in participants from each agegroup receiving MenQuadfi Vaccine

Detailed description: Study duration per participant will be approximately: 7 months for Stage 1 participants, 12 to 18.5 months for Stage 2 participants, 12 months for Stage 3 participants and 18 months for Stage 4 participants

In each vaccine group at each age group (Stage 1, 3 and 4 only), the first 5 participants enrolled (sentinels) will be assessed via early safety data review (ESDR) as a cohort for the evaluation of biological safety and overall safety profile for D01-D08 post dose 1. The safety data collected will be reviewed before proceeding with recruitment of remaining participants in each study group. Enrollment of remaining participants randomized to each group will be based on the outcome of the safety assessments of the sentinels: only a positive review outcome will allow the enrollment of the sentinel cohort of the respective lower age group.
