Abstract: A multi-valent vaccine composition is described comprising a conjugate of the capsular polysaccharide of H. influenzae b not adsorbed onto an aluminium adjuvant salt, and two or more further bacterial polysaccharides. A multi-valent vaccine composition is also described comprising a whole-cell pertussis component, tetanus toxoid, diphtheria toxoid, Hepatitis B surface antigen, a conjugate of the capsular polysaccharide of H. influenzae b, and a conjugate of a capsular polysaccharide of N. meningitidis type A or C (or both). Furthermore, a multi-valent vaccine composition is described comprising a whole-cell pertussis component, tetanus toxoid, diphtheria toxoid, and a low dose of a conjugate of the capsular polysaccharide of H. influenzae b.

Abstract: The present invention is in the field of pneumococcal capsular saccharide conjugate vaccines. Specifically, a multivalent Streptococcus pneumoniae immunogenic composition is provided with various (for instance 9 or more) conjugated capsular saccharides from different S. pneumoniae serotypes, wherein the composition comprises conjugated capsular saccharide 18C which is less than 80, 70, 60, 50, 40, 30, 20, 15 or 10% O-Acetylated.

Abstract: The present invention relates to the field of neisserial vaccine compositions, their manufacture, and the use of such compositions in medicine. More particularly it relates to processes of making novel engineered meningococcal strains which are more suitable for the production of neisserial, in particular meningococcal, outer-membrane vesicle (or bleb) vaccines. Advantageous processes and vaccine products are also described based on the use of novel LOS subunit or meningococcal outer-membrane vesicle (or bleb) vaccines which have been rendered safer and/or more effective for use in human subjects. In particular combinations of gene downregulations are described such as PorA and OpA, PorA and OpC, OpA and OpC, and PorA and OpA and OpC. Alternatively, or in addition, lgtB? is shown to be an optimal mutation for effectively and safely using L3 and/or L2 LOS in Neisseria vaccine compositions.

Abstract: The present invention discloses a Gram negative bacterium in which the expression of a protein involved in LPS transport to the outer membrane is functionally down-regulated such that the level of LPS in the outer membrane is decreased compared to a wild-type Gram negative bacterium. Down regulation of Imp and MsbA proteins can result in such a bacterium. Outer membrane vesicle preparations derived from the Gram negative bacterium of the invention can be used in vaccines to provide protection against bacterial infection.

Abstract: The present invention relates to immunogenic compositions and vaccines for the treatment and prevention of Neisserial disease. Immunogenic compositions of the invention contain combinations of antigens selected from at least two different classes of antigens including adhesins, autotransporter proteins, toxins, iron acquisitions proteins and membrane-associated protein (preferably integral outer membrane protein)s. Such combinations of antigens are able to target the immune response against different aspects of the neisserial life cycle, resulting in a more effective immune response.

Abstract: The present invention relates to immunogenic compositions comprising neisserial blebs with upregulated levels of the NMB0964 antigens such that bacterial antibodies are generated against said antigen. Methods are also provided to upregulate expression through removal of the zinc repression mechanism of the cell or promoter or through removal of zinc from the culture medium.

Abstract: The present invention relates to the field of Serum Bactericidal Activity (SBA) assays for Gram negative bacteria, in particular N. meningitidis. The SBA assay is the most important method for measuring functional activity of serum antibodies against meningococcus. In order to determine whether a subject or a population is seropositive against invasive meningococcus the SBA test should ideally be both sensitive and specific. The inventors have found the standard N. meningitidis serotype A and W SBAs can be significantly improved in this regard.
