• Available for the entire study period and can be reached by telephone.

• Healthy participant as determined by medical history, physical examination, and judgement of the investigator.

Exclusion Criteria:

• A previous anaphylactic reaction to any vaccine or vaccine-related component.

• Bleeding diathesis or condition associated with prolonged bleeding time that would contraindicate intramuscular injection.

• A known or suspected defect of the immune system that would prevent an immune response to the vaccine, such as participants with congenital or acquired defects in B-cell function, those receiving chronic systemic (oral, intravenous, or intramuscular) corticosteroid therapy, or those receiving immunosuppressive therapy.

• History of microbiologically proven disease caused by Neisseria meningitidis or Neisseria gonorrhoeae.

• Significant neurological disorder or history of seizure (excluding simple febrile seizure).

• Any neuroinflammatory or autoimmune condition, including, but no limited to, transverse myelitis, uveitis, optic neuritis, and multiple sclerosis.

• Participants receiving any allergen immunotherapy with a nonlicensed product or receiving allergen immunotherapy with a licensed product and are not on stable maintenance doses.

• Receipt of any blood products, including immunoglobulin, within 6 months before the first study vaccination.

• Current use of systemic antibiotics with no foreseeable date of discontinuation prior to anticipated date of enrollment (first vaccination).
