Are you eligible to participate in this study?

You may be eligible for this study if you meet the following criteria:

  • Conditions: Meningococcal infection
  • Age: Between 1 - 1 Years
  • Gender: Male or Female

Inclusion Criteria:

  • Aged 42 to 89 days on the day of the first study visit
  • Healthy infants as determined by medical history, physical examination and judgment of the Investigator
  • Informed consent form has been signed and dated by the parent(s) or other legally acceptable representative (and by an independent witness if required by local regulations)
  • Subject and parent/legally acceptable representative are able to attend all scheduled visits and to comply with all study procedures
  • Covered by health insurance according to local regulations

Exclusion Criteria:

  • Participation at the time of study enrollment (or in the 4 weeks preceding the first study vaccination) or planned participation during the present study period in another clinical study investigating a vaccine, drug, medical device, or medical procedure
  • Receipt of any vaccine in the 4 weeks preceding the first study vaccination or planned receipt of any vaccine in the 4 weeks before and/or following any study vaccination except for influenza vaccination and rotavirus vaccination, which may be received at a gap of at least 2 weeks before or 2 weeks after any study vaccines. This exception includes monovalent pandemic influenza vaccines and multivalent influenza vaccines. This exclusion criterion does not apply to subjects in Finland who plan to receive the licensed rotavirus vaccine during study vaccination visits.
  • Receipt or planned to receipt during the study period vaccination against meningococcal disease with either the study vaccine or another vaccine (i.e., mono- or polyvalent, polysaccharide, or conjugate meningococcal vaccine containing serogroups A, C, Y, or W; or meningococcal B serogroup-containing vaccine)
  • Previous vaccination against diphtheria, tetanus, pertussis, Haemophilus influenzae type B (Hib), poliovirus, Streptococcus pneumoniae, measles, mumps, or rubella. Previous vaccination against hepatitis B when administered to risk groups, as per local recommendation.
  • Receipt of immune globulins, blood or blood-derived products since birth
  • Known or suspected congenital or acquired immunodeficiency; or receipt of immunosuppressive therapy, such as anti-cancer chemotherapy or radiation therapy; or long-term systemic corticosteroid therapy (prednisone or equivalent for more than 2 consecutive weeks) since birth
  • Family history of congenital or hereditary immunodeficiency, unless the immune competence of the potential vaccine recipient is demonstrated
  • Individuals with blood dyscrasias, leukemia, lymphoma of any type, or other malignant neoplasms affecting the bone marrow or lymphatic systems
  • Individuals with active tuberculosis
  • History of Neisseria meningitidis infection, confirmed either clinically, serologically, or microbiologically
  • History of diphtheria, tetanus, pertussis, poliomyelitis, hepatitis B, measles, mumps, rubella, and of Haemophilus influenzae type b, and / or Streptococcus pneumoniae infection or disease
  • At high risk for meningococcal infection during the study (specifically, but not limited to, subjects with persistent complement deficiency, with anatomic or functional asplenia, or subjects traveling to countries with high endemic or epidemic disease)
  • Individuals with underlying conditions predisposing them to invasive pneumococcal disease (specifically, but not limited to, subjects with sickle cell disease or human immunodeficiency virus [HIV] infection)
  • History of any neurologic disorders, including seizures and progressive neurologic disorders
  • History of Guillain-Barr syndrome
  • Known systemic hypersensitivity to any of the vaccine components, or history of a severe allergic reaction (e.g., anaphylaxis) to the vaccine(s) used in the study or to a vaccine containing any of the same substances including neomycin, streptomycin, polymyxin B, glutaraldehyde, formaldehyde, and gelatin
  • Verbal report of thrombocytopenia, contraindicating intramuscular vaccination in the investigator's opinion
  • Bleeding disorder, or receipt of anticoagulants in the 3 weeks preceding inclusion, contraindicating intramuscular vaccination in the investigator's opinion
  • Chronic illness (including, but not limited to, cardiac disorders, congenital heart disease, chronic lung disease, renal disorders, auto-immune disorders, diabetes, psychomotor diseases, and known congenital or genetic diseases) that, in the opinion of the investigator, is at a stage where it might interfere with study conduct or completion
  • Any condition which, in the opinion of the investigator, might interfere with the evaluation of the study objectives, including planning to leave the area of the study site before the end of the study
  • Moderate or severe acute illness/infection (according to investigator judgment) on the day of vaccination or febrile illness (temperature 38.0C). A prospective subject should not be included in the study until the condition has resolved or the febrile event has subsided.
  • Receipt of oral or injectable antibiotic therapy within 72 hours prior to the first blood draw
  • Identified as a natural or adopted child of the Investigator or employee with direct involvement in the proposed study
  • Infants born preterm (by less than 37 weeks of gestation) requiring specific immunization schedule for routine childhood vaccines and/or specific care at the time of vaccination, as per national recommendations
