The purpose of this study is to determine whether a vaccine based on outer membrane vesicles (NOMV) from genetically detoxified group B meningococcus is safe and effective for use as a vaccine. If so, the NOMV in this vaccine will be combined with NOMV from two other genetically modified strains as a potentially globally effective vaccine against group B meningococcus.

  • Has received or plans to receive any live vaccine, Investigational New Drug (IND) products or significant immunosuppressive therapy* in the 28 days prior to, or any inactivated vaccine within 14 days before initial vaccination or throughout the study, or received parenteral immunoglobulin or blood products within 3 months of study initiation;

    • (Intra-articular, topical, or intranasal steroids, steroids applied to the eye, or ≤ 7 days of oral steroids are in general acceptable, depending on the formulation and condition for which they are prescribed. Inclusion of individuals receiving these medications will be made by the PI on a case by case basis)
  • High levels of baseline bactericidal antibodies against the vaccine strain on screening (>1:16) and/or throat carriage of Neisseria meningitidis at time of screening;
