This disclosure provides a new vaccine composition and methods for its use. The composition contains an effective amount of each of: an aluminum hydroxide, a mono-phosphoryl lipid (MPL), and a whole glucan particles (WGP) but no an antigen that raises an immune response against a bacterial or fungal infection.

The present invention relates to a process for preparing immunogenic compositions. More particularly, it relates to a process for preparing liquid compositions of Protein D polypeptide and their use in preparing immunogenic compositions comprising Protein D polypeptide which may be used in the treatment or prevention of an acute exacerbation of chronic obstructive pulmonary disease (AECOPD) in a subject, e.g. human.

Immunogenic proteins from Moraxella catharrhalis as well as nucleic acids, vectors and transformed cells useful for expression of the proteins. Methods for prophylaxis of infection with Moraxella catharrhalis using the proteins, nucleic acids, vectors or transformed cells.

The present invention discloses a Acinetobacter baumannii immunogenic protein and its composition and application. This invention provides a protein, comprising 39 amino acids of the N-terminal -helix part of the Ata protein transport functional domain of Acinetobacter baumannii and an adjuvant protein; amino acid sequence of said 39 amino acids of the N-terminal -helix part of the Ata protein transport functional domain of Acinetobacter baumannii is shown as the 127.sup.th-165.sup.th amino acid residues of SEQ ID NO:2. In present invention the 39 amino acids of the N-terminal -helix part of surface protein Ata (Acinetobacter trimeric autotransporter) of Acinetobacter baumannii, was took to fuse with CTB, and express in BL21. The protein was purified by a nickel column, and used to intraperitoneally immunize mouses by 2.5 g/mouse. Its immunogenicity and immunoprotection was verified through the animal experiments, which proves it has a good effect of anti-infection of Acinetobacter baumannii.

A vaccine delivery method is presented that includes a composition including as one component a slurry matrix that is a liquid at room temperature and a gel at physiological pH, physiological salt concentrations and/or physiological temperatures and as a second component one or more antigens. Also included are methods of inducing an immune response in a subject and vaccinating a subject by administering such compositions.

The present invention relates to the field of immunogenic compositions and vaccines and the use of such compositions in medicine. More particularly, it relates to immunogenic fragments of UspA2 comprising an epitope and immunogenic compositions and vaccines comprising said fragments, for use in preventing or treating an infection, disease or condition caused by heterologous strain(s) of Moraxella catarrhalis. The invention further relates to immunogenic compositions and vaccines comprising an immunogenic fragment wherein said fragment comprises an epitope with cross-bactericidal activity.

This disclosure provides a new vaccine composition and methods for its use. The composition contains an effective amount of each of: an aluminum hydroxide, a mono-phosphoryl lipid (MPL), and a whole glucan particles (WGP) but no an antigen that raises an immune response against a bacterial or fungal infection.

The present invention relates to compositions comprising Moraxella catarrhalis (M. catarrhalis) Ubiquitous surface protein A2 (UspA2). More particularly, the present application relates to UspA2 protein constructs and immunogenic compositions comprising the constructs, vaccines comprising such immunogenic compositions and therapeutic uses of the same. The invention further relates to compositions comprising UspA2 in combination with at least one antigen from Haemophilus influenzae, immunogenic compositions comprising the antigens, vaccines comprising such immunogenic compositions and therapeutic uses of the same.

The present disclosure relates to surface proteins of Moraxella catarrhalis and their ability to interact with epithelial cells via cell-associated fibronectin and laminin, and also to their ability to inhibit the complement system. These surface proteins are useful in the preparation of vaccines. The present disclosure also provides peptides interacting with fibronectin, laminin and the complement system.
