Overview
Brief Summary
The purpose of this trial is to evaluate the immunogenicity, the safety and the tolerability of rMenB+OMV NZ and MenACWY vaccines in healthy infants, when concomitantly administered at 3, 5, 7 and 13 months of age, compared to either alone.
Investigators
Eligibility Criteria
Inclusion Criteria
- •Healthy 3-month old infants (85-119 days, inclusive) at time of Visit 1 whose parents/legal guardians have given written informed consent after the nature of the study has been explained.
- •Available for all the visits scheduled in the study.
- •In good health as determined by medical history, physical examination and clinical judgment of the investigator.
Exclusion Criteria
- •History of any previous immunization with a meningococcal vaccine or vaccine containing meningococcal antigen(s) at the time of enrollment.
- •Previous known or suspected disease caused by N. meningitidis.
- •Household contact with and/or intimate exposure to an individual with laboratory confirmed N. meningitidis infection or colonization.
- •History of severe allergic reaction after previous vaccinations, or hypersensitivity to any component of the vaccine.
- •Known or suspected autoimmune disease or impairment/alteration of the immune system resulting from, for ex-ample:
- •Chronic administration of immunosuppressants or other immune-modifying drugs since birth (3 months prior). (For corticosteroids, this means prednisone, or equivalent, ≥ 0.5 mg/kg/day or ≥ 10 mcg/day for children below 2 years. Inhaled and topical steroids are allowed),
- •Immune deficiency disorder, or known HIV infection.
- •Receipt of blood, blood products and/or plasma derivatives or any parenteral immunoglobulin preparation since birth.
- •History of any progressive or severe neurologic disorder, or seizure disorder or Guillan Barré syndrome (exception: one self-limited febrile seizure is acceptable).
- •History of any bleeding disorder considered as a contraindication to intramuscular injection or blood draw.
Outcomes
Primary Outcomes
Human Serum Bactericidal Activity (hSBA) Geometric Mean Titers (GMTs) Against Each of the Serogroup B Indicator Strains
Time Frame: At Day 331 (one month after the fourth vaccination)
Human serum bactericidal activity (hSBA) titers against each of the serogroup B indicator strains-H44/76,5/99,NZ98/254 \& M10713 after receiving 4 doses of rMenB+OMV NZ / MenACWY vaccines, concomitantly administered, versus corresponding response in subjects who received rMenB+OMV NZ administered alone, were presented in terms of vaccine group specific geometric mean titers (GMTs). This outcome measure applies to only rMenB+ACWY and rMenB groups as the serogroup B indicator strains were assessed only for these two groups.
hSBA Geometric Mean Titers (GMTs) Against Each of the Serogroups A, C, W-135 and Y
Time Frame: At Day 331 (one month after the fourth vaccination)
hSBA titers against N. meningitidis serogroups A, C, W-135 and Y after receiving four doses of either rMenB+OMV NZ / MenACWY concomitantly administered versus corresponding response in subjects who received MenACWY administered alone were presented in terms of vaccine group specific GMTs. This outcome measure applies to only rMenB+ACWY and MenACWY groups as the serogroups A,C,W-135 \& Y were assessed only for these two groups.
