Factor H binding proteins (fHBP), are bacterial surface proteins currently undergoing human clinical trials as candidate serogroup B Neisseria meningitidis (MnB) vaccines. fHBP protein sequences segregate into two distinct subfamilies, designated A and B. Here, we report the specificity and vaccine potential of mono- or bivalent fHBP-containing vaccines. A(More)
BACKGROUND Recombinant forms of Neisseria meningitidis human factor H binding protein (fHBP) are undergoing clinical trials in candidate vaccines against invasive meningococcal serogroup B disease. We report an extensive survey and phylogenetic analysis of the diversity of fhbp genes and predicted protein sequences in invasive clinical isolates obtained in(More)
Neisseria meningitidis (Nm) serogroups B, C and Y are the major causes of meningococcal diseases in the United States. NmB accounts for ∼1/3 of the disease but no licensed vaccine is yet available. Two candidate vaccines are being developed specifically to target NmB, but may also provide protection against other serogroups. To assess the potential impact(More)
BACKGROUND Recombinant vaccines containing factor H-binding protein (fHBP) have been developed for the purpose of protection from invasive meningococcal serogroup B disease. Neisseria meningitidis fHBP sequences can be divided into 2 genetically and immunologically distinct subfamilies (A and B); thus, cross protection is conferred within but not between(More)
Clumping factors A (ClfA) and B (ClfB) are Staphylococcus aureus virulence proteins that are displayed on the cell surface of the organism and have potential as vaccine antigens for the prevention of S. aureus disease. Here we evaluate the phylogeny of S. aureus in the context of antigenic variation of these two surface proteins. ClfA and ClfB gene(More)
OBJECTIVES Bivalent rLP2086 (Trumenba®; MenB-FHbp), composed of two factor H binding proteins (FHbps), is a vaccine approved in the United States for prevention of Neisseria meningitidis serogroup B (MnB) invasive meningococcal disease (IMD). Bactericidal activity of sera from subjects vaccinated with bivalent rLP2086 was assessed against MnB isolates from(More)
Neisseria meningitidis serogroup B (MnB) is a leading cause of bacterial meningitis; however, MnB is most commonly associated with asymptomatic carriage in the nasopharyngeal cavity, as opposed to the disease state. Two vaccines are now licensed for the prevention of MnB disease; a possible additional benefit of these vaccines could be to protect against(More)
