Bactericidal Antibody Responses Elicited by a Meningococcal Outer Membrane Vesicle Vaccine with Overexpressed Factor H–Binding Protein and Genetically Attenuated Endotoxin

摘要

Background. Outer membrane vesicle (OMV) vaccines from mutant Neisseria meningitidis strains engineered to overexpress factor H-binding protein (fHbp) have elicited broadly protective serum antibody responses in mice. The vaccines investigated were not treated with detergents to avoid extracting fHbp, which is a lipoprotein. Because of their high endotoxin content, the vaccines would not be safe to administer to humans.
