Group B Meningococcal Vaccine
A Phase 1 Dose-Escalation Study of the Safety and Immunogenicity of Three Injections, Given at 0, 6, and 12 Weeks, of Group B Meningococcal 8570 HOPS-G NOMV Vaccine Administered Intramuscularly to Healthy Subjects at 10, 25, 50, or 75 μg With Adjuvant
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.
