In one aspect, the invention relates to a composition including a factor H binding protein (fHBP) and a Neisseria meningitidis non-serogroup B capsular polysaccharide. The invention further relates to uses of a composition that includes fHBP, such as, for example, uses to elicit an immune response against N. meningitidis serogroup B strains and non-serogroup B strains. The compositions and methods described herein are directed to administration in humans, including adults, adolescents, toddlers, and infants.

Novel multivalent polysaccharide-protein conjugate vaccine formulation. The formulation is liquid or lyophilized or a Liquid-Lyo combination pentavalent formulation of Neisseria meningitidis serogroup A, C, Y, W and X capsular polysaccharides (Men A, C, Y, W, X), each said polysaccharide being conjugated separately to tetanus toxoid (TT) carrier protein to obtain Men A, C, Y, W, X-TT conjugates, with one or more buffer and with or without an adjuvant along with pharmaceutically acceptable components/excipients.

The present invention relates to Neisseria ORF2086 proteins, crossreactive immunogenic proteins which can be isolated from nesserial strains or prepared recombinantly, including immunogenic portions thereof, biological equivalents thereof, antibodies that immunospecifically bind to the foregoing and nucleic acid sequences encoding each of the foregoing, as well as the use of same in immunogenic compositions that are effective against infection by Neisseria meningitidis serogroup B.
