All of the foregoing applications are hereby incorporated by reference in their entireties. REFERENCE TO SEQUENCE LISTING This application is being filed electronically via EFS-Web and includes an electronically submitted sequence listing in .xml format. The .xml file contains a sequence listing entitled “PC072522B Sequence Listing.xml” created on Jun. 24, 2025 and having a size of 102,400 bytes. The sequence listing contained in this .xml file is part of the specification and is incorporated herein by reference in its entirety. FIELD OF THE DISCLOSURE The present disclosure relates to Neisseria meningitidis compositions and methods thereof. BACKGROUND OF THE DISCLOSURE Neisseria meningitidis is a Gram-negative encapsulated bacterium that can cause sepsis, meningitis, and death. N. meningitidis can be classified into at least 12 serogroups (including serogroups A, B, C, 29E, H, I, K, L, W-135 (mostly now referred to as W), X, Y and Z) based on chemically and antigenically distinctive polysaccharide capsules. Strains with five of the serogroups (A, B, C, Y, and W135) are responsible for the majority of disease. Meningococcal meningitis is a devastating disease that can kill children and young adults within hours despite the availability of antibiotics. There is a need for improved immunogenic compositions against meningococcal serogroups A, B, C, Y, and W135 and/or X. Currently, a cross-protective vaccine or composition effective against a wide range of MnB and meningococcal serogroups A, C, Y, and W and/or X isolates is not yet commercially available. Accordingly, a cross-protective vaccine or composition effective against diverse MnB and meningococcal serogroups A, C, Y, and W and/or X isolates is needed. It is a further object of the disclosure to provide improved schedules for administering a meningococcal vaccine. Under the current recommendation scheme, there are four to five vaccinations given against meningococcal serogroups A, C, W, Y and B, given at different ages. There is an unmet need for efficient vaccinations that may to simplify immunization schedules and improve vaccination coverage to achieve further reductions in invasive meningococcal disease (IMD). SUMMARY OF THE DISCLOSURE To meet these and other needs, the present disclosure relates to Neisseria meningitidis compositions and methods thereof. The inventors discovered a method of inducing an immune response in a human, including administering to the human a composition comprising a) a polypeptide derived from a Neisseria meningitidis factor H binding protein (fHBP); (b) a Neisseria meningitidis serogroup A capsular saccharide conjugate; (c) a Neisseria meningitidis serogroup C capsular saccharide conjugate; (d) a Neisseria meningitidis serogroup W capsular saccharide conjugate; and (e) a Neisseria meningitidis serogroup Y capsular saccharide conjugate, wherein the composition induces an immune response to at least one of N. meningitidis serogroups A, C, W-135 and Y capsular polysaccharides and N. meningitidis serogroup B, wherein the immune response includes a titer of serum bactericidal antibodies that is higher than a titer of serum bactericidal antibodies induced by a respective licensed vaccine against the serogroup. The inventors surprisingly discovered a method of inducing an immune response in a human, including administering to the human a composition comprising a) a first polypeptide derived from a Neisseria meningitidis factor H binding protein (fHBP); (b) a second polypeptide derived from a Neisseria meningitidis factor H binding protein (fHBP); (c) a Neisseria meningitidis serogroup A capsular saccharide conjugate; (d) a Neisseria meningitidis serogroup C capsular saccharide conjugate; (e) a Neisseria meningitidis serogroup W capsular saccharide conjugate; and (f) a Neisseria meningitidis serogroup Y capsular saccharide conjugate, wherein the composition induces an immune response to at least one of N. meningitidis serogroups A, C, W-135 and Y capsular polysaccharides and N. meningitidis serogroup B, wherein the immune response includes a titer of serum bactericidal antibodies that is higher than a titer of serum bactericidal antibodies induced by a respective licensed vaccine against the serogroup. In some embodiments, the polypeptide includes an amino acid sequence having at least 70% identity to any one amino acid sequence selected from SEQ ID NO: 1 to SEQ ID NO: 62. In a preferred embodiment, the composition includes (a) a first polypeptide including the amino acid sequence set forth in SEQ ID NO: 1; (b) a second polypeptide including the amino acid sequence set forth in SEQ ID NO: 2; (c) a Neisseria meningitidis serogroup A capsular saccharide conjugated to an adipic acid dihydrazide (ADH) linker
