Brief Summary:
This study is to assess the longevity of immune response in adolescents for approximately 48 months after receipt of a primary series of bivalent rLP2086 vaccination, which is then followed by a booster dose and an assessment of immune response for 12 or 26 months post booster vaccination.

Condition or disease Intervention/treatment Phase
Meningococcal Infection Procedure: blood sampling Drug: bivalent rLP2086 Phase 3

Detailed Description:

This study is to assess the longevity of immune responses in adolescents (aged 10 to <19 years at the time of entry into a primary study) following receipt of a vaccination regimen of 2 or 3 doses of bivalent rLP2086 in a primary study. A booster dose of bivalent rLP2086 at approximately 48 months was given following the final dose of the 2- or 3-dose primary bivalent rLP2086 vaccination series. The study was therefore divided into Stage 1 (4-year persistence of immune responses following receipt of a primary vaccination series) and the booster stage (follow-up through 12 months for all boosted or 26 months for a subset of the boosted).

Subjects participating only in Stage 1 will attend up to 6 study visits for collection of a 20-mL blood sample at each visit. Subjects participating in both Stage 1 and booster stage will attend up to 9-10 study visits with 1 visit for booster dose vaccination and 8-9 visits for collection of a 20-mL blood sample at each visit.
