A Trial to Assess the Safety, Tolerability, and Immunogenicity of Bivalent rLP2086 Vaccine When Given to Healthy Young Adults Aged >=18 to <26 Years.

Study Overview
=================
Brief Summary
-----------------
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 adults. The study will also look at the safety of the new vaccine as well as how it is tolerated.

Official Title

Participation Criteria

Eligibility Criteria
-----------------
Inclusion Criteria: Male or female subject aged >=18 and <26 years at the time of enrollment. Healthy subject as determined by medical history, physical examination, and judgment of the investigator. Negative urine pregnancy test for all female subjects. Exclusion Criteria: Previous vaccination with any meningococcal serogroup B vaccine. Subjects who are scheduled to receive 1 or more doses of an HPV vaccine as part of a 3-dose series during the period between Visit 1 and 28 days after the second vaccination. Subjects receiving any allergen immunotherapy with a nonlicensed product or receiving allergen immunotherapy with a licensed product and are not on stable maintenance doses. 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 in the United States with terminal complement deficiency are excluded from participation in this study. Significant neurological disorder or history of seizure (excluding simple febrile seizure). Current chronic use of systemic antibiotics. Received any investigational vaccines, drugs, or devices within 28 days before administration of the first study vaccination. Any neuroinflammatory or autoimmune condition, including, but not limited to, transverse myelitis, uveitis, optic neuritis, and multiple sclerosis.
