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 characterized 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.

Abstract: The present invention is directed to improved microbial antigen vaccines, pharmaceutical compositions, immunogenic compositions and antibodies and their use in the treatment of microbial infections, particularly those of bacterial origin, including Staphylococcal origin. Ideally, the present invention is directed to a recombinant staphylococcal MSCRAMM or MSCRAMM-like proteins, or fragment thereof, with reduced binding to its host ligand, for use in therapy.

Abstract: The present invention relates to ClfA polypeptides wherein amino acid Y474 or an amino acid adjacent to Y474 is mutated such that fibrinogen binding activity is decreased compared to an equivalent ClfA polypeptide without mutation of Y474 or an amino acid adjacent to Y474 as well as immunogenic compositions, vaccines, processes and uses of such mutated ClfA polypeptides.

Abstract: This invention relates to three newly-identified, distinct groups of antigenic peptides [LB1(f) peptides] from the same region of the P5-like fimbrin protein discovered using sequence data from the fimbrin protein of many Haemophilus influenzae strains. The invention additionally provides chimeric polypeptides that carry one or more representatives of such peptides from different groups and which induce an immunogenic response in animals to Haemophilus influenzae. The peptides and polypeptides of the invention will be useful in vaccine compositions which provide protection against a wide range of H. influenzae strains.

Abstract: The present invention relates to the field of vaccine formulation, particularly the field of novel adjuvant compositions comprising outer membrane vesicles (or blebs), and advantageous methods of detoxifying these compositions, and advantageous methods of use of such adjuvants.
