A Study to Describe the Immunogenicity, Safety, and Tolerability of Neisseria Meningitidis Serogroup B Bivalent Recombinant Lipoprotein 2086 Vaccine (Bivalent rLP2086) in Healthy Subjects Aged ≥24 Months to <10 Years

A Phase 2, Randomized, Controlled, Observer-blinded Study To Describe The Immunogenicity, Safety, And Tolerability Of Neisseria Meningitidis Serogroup B Bivalent Recombinant Lipoprotein 2086 Vaccine (Bivalent Rlp2086) In Healthy Subjects Aged >/= 24 Months To <10 Years

This study is looking at a new vaccine that might prevent meningococcal disease, and will study the immune response elicited by this vaccine when given to healthy young children. The study will also look at the safety of the new vaccine as well as how it is tolerated.

5. A previous anaphylactic reaction to any vaccine or vaccine-related component.
6. Bleeding diathesis or condition associated with prolonged bleeding time that would contraindicate intramuscular injection.
7. A known or suspected defect of the immune system that would prevent an immune response to the vaccine, such as subjects with congenital or acquired defects in B-cell function, those receiving chronic systemic (oral, intravenous, or intramuscular) corticosteroid therapy, or those receiving immunosuppressive therapy. Subjects with terminal complement deficiency may be included. Additional details will be provided in the study reference manual (SRM).

13. Any neuroinflammatory or autoimmune condition, including but not limited to transverse myelitis, uveitis, optic neuritis, and multiple sclerosis.
14. Other severe acute or chronic medical or psychiatric condition or laboratory abnormality that may increase the risk associated with study participation or investigational product administration or may interfere with the interpretation of study results and, in the judgment of the investigator, would make the subject inappropriate for entry into this study.
15. Pregnant female subjects, breastfeeding female subjects, male subjects with partners who are currently pregnant, or male and female subjects of childbearing potential who are unwilling or unable to use a highly effective method of contraception as outlined in this protocol for the duration of the study.
