Abstract: The present invention relates to an immuno-protective and non-toxic Gram-negative bleb vaccine suitable for paediatric use. Examples of the Gram-negative strains from which the blebs are made are N. meningitidis, M. catarrhalis and H. influenzae. The blebs of the invention are improved by one or more genetic changes to the chromosome of the bacterium, including up-regulation of protective antigens, down-regulation of immunodominant non-protective antigens, and detoxification of the Lipid A moiety of LPS.

The invention further provides immunogenic compositions comprising a plurality of antigens selected from at least two different categories of antigen, having different functions within Bordetella. Examples of such categories of antigen are autotransporter proteins, iron acquisition proteins, lipoproteins, adhesins and toxins/invasins.

Abstract: The present application discloses an immunogenic composition comprising a Hib saccharide conjugate, at least one additional bacterial, for example N. meningitidis, saccharide conjugate(s), and a further antigen selected from the group consisting of whole cell pertussis and hepatitis B surface antigen, wherein the saccharide dose of the Hib saccharide conjugate is less than 5 ?g.

Abstract: An immunogenic composition comprising a Hib saccharide conjugate and at least two further bacterial saccharide conjugates is provided, wherein the Hib conjugate is present in a lower saccharide dose than the mean saccharide dose of all the at least two further bacterial saccharide conjugates.

Abstract: The present application discloses an immunogenic composition comprising a Hib saccharide conjugate, at least one additional bacterial, for example N. meningitidis, saccharide conjugate(s), and a further antigen selected from the group consisting of whole cell pertussis and hepatitis B surface antigen, wherein the saccharide dose of the Hib saccharide conjugate is less than 5 ug.

Abstract: Immunogenic compositions and methods of treating a Streptococcus pneumoniae infection are described herein.

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 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.
