History of culture-proven disease caused by N meningitidis or Neisseria gonorrhoeae. 5. Bleeding diathesis or condition associated with prolonged bleeding time that would contraindicate blood draw. 6. Receipt of any blood products, including gamma globulin, in the period from 6 months before any study visit. 7. Vaccination with any licensed or experimental meningococcal serogroup B vaccine since being enrolled in the primary Pfizer-sponsored MnB study (other than study vaccines permitted in the primary study). 8. Subjects who were not compliant with primary study eligibility criteria while enrolled in the primary study. Booster Stage: 1.

A previous anaphylactic reaction to any vaccine or vaccine-related component. 3. Subjects receiving any allergen immunotherapy with a nonlicensed product or receiving allergen immunotherapy with a licensed product and are not on stable maintenance doses. 4. Bleeding diathesis or condition associated with prolonged bleeding time that would contraindicate intramuscular injection. 5. 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. Please refer to the study reference manual (SRM) for additional details. 6. Significant neurological disorder or history of seizure (excluding simple febrile seizure). 7. Current chronic use of systemic antibiotics. 8. Current participation in another investigational study. Participation inpurely observational studies is acceptable. 9. Received any investigational vaccines, drugs, or devices within 28 days before administration of the booster vaccination. 10. Any neuroinflammatory or autoimmune condition, including, but not imited to, transverse myelitis, uveitis, optic neuritis, and multiple sclerosis. 11. Pregnant female subjects

Primary Outcome(s)
|
Primary end point(s): The 4 primary test strains for hSBA testing are PMB80 (A22 variant),PMB2001 (A56), PMB2948 (B24), and PMB2707 (B44). The lower limit of quantitation (LLOQ) for PMB80 (A22) is an hSBA titer equal to 1:16. The LLOQ for the other 3 primary test strains is an hSBA titer equal to 1:8. hSBA assays using the 4 primary test strains will be conducted using sera obtained at Visits 1 to 6 from all subjects entered into stage 1, including subjects who did not receive bivalent rLP2086 in the primary study (B1971015 Group 2). Stage 1: Proportion of subjects with hSBA titers = LLOQ for each of the 4 primary strains at each blood draw visit in Stage 1 (Visits 1-6).
Booster Stage - Proportions of subjects with hSBA titers = LLOQ for each of the 4 primary strains at 1 month following the last vaccination received in the primary study, before the booster vaccination (Visit 6), and 1 month, 12 months amd 26 months( Visit 8, 10, and 11) following booster vaccination.
Safety Endpoints (Booster Stage): - Percentages of subjects reporting local reactions via the electronic diary (e-diary) by type (pain at the injection site, redness, and swelling) and by severity after a booster vaccination of bivalent rLP2086.
- Percentages of subjects reporting systemic events via the e-diary by type (fever, vomiting, diarrhea, headache, fatigue, chills, muscle pain other than muscle pain at the injection site, and joint pain) and by severity after a booster vaccination of bivalent rLP2086.
- Percentage of subjects reporting the use of antipyretic medication via the e-diary after a booster vaccination of bivalent rLP2086.
- Percentages of subjects with at least 1 AE occurring during the following time periods: - From Visit 7 to Visit 8
- Percentages of subjects with at least 1 SAE during the following periods: - From Visit 7 to Visit 8 - From Visit 8 to Visit 9 - From Visit 7 to 9
- Percentages of subjects with at least 1 NDCMC occurring during the following time periods: - From the 6-month safety telephone call in the primary study to Visit 6 (Stage 1)
- From Visit 7 to Visit 8 - From Visit 8 to Visit 10 - From Visit 7 to Visit 10 - From Visit 8 to Visit 11 (only subjects proceeding to Visit 11) - From Visit 7 to Visit 11 (only subjects proceeding to Visit 11)
- Percentages of subjects with at least 1 medically attended event occurring during the following time periods: From Visit 7 to Visit 8 - From Visit 8 to Visit 9 - From Visit 7 to Visit 9 Percentage of subjects reporting at least 1 immediate AE after receiving the booster dose of bivalent rLP2086. Number of days subjects miss school or work because of AEs from Visit 7 through Visit 9. For the Exploratory Endpoints for Stage 1 and Booster Stage: Please refer to Protocol Section 2.2.4.

Main Objective: Stage 1: To describe the immunogenicity of bivalent rLP2086 as determined by hSBA titers to 4 primary test strains at approximately 6, 12, 18, 24, 36, and 48 months after the last dose (second or third dose) of bivalent rLP2086 or saline in the primary study (ie, a previously conducted Pfizer study using the final formulation and dose of bivalent rLP2086). Booster Stage: To describe the immune response as measured by hSBA titers to 4 primary test strains 1 month after the last dose (second or third dose) of bivalent rLP2086 in the primary study, before the booster vaccination, and 1 month, 12 months and 26 months after a single booster dose of bivalent rLP2086. Primary Safety Objective (Booster Stage): Please refer to the Protocol Section 2.1.2. Exploratory Objectives for Stage 1 and Booster Stage): Please refer to the Protocol Section 2.1.3
