A dual formulation for vaccines against Neisseria meningitidis serogroup B('Men-B') comprises (i) an oil-in-water emulsion adjuvant and (ii) a Men-B immunogenic component in lyophilised form. The lyophilised Men-B antigens can be reconstituted into liquid adjuvanted form at the time of use ready for administration to a patient. This formulation has been found to give excellent result in terms of both stability and immunogenicity. The lyophilised component can also include one or more conjugated saccharides from N. meningitidis in serogroups A, C, W135 and/or Y.
