The present invention relates to the field of veterinary vaccinology, namely to combination vaccines for swine. In particular the invention relates to a combination vaccine for protection against a pathogenic infection with porcine circo vims type 2 (PCV2) and Mycoplasma hyopneumoniae (Mhyo) comprising non-replicating immunogen of PCV2 and non-replicating immunogen of Mhyo. The vaccine is characterized in that it is an oil-in-water emulsion comprising squalane, vitamin E-acetate and silica. In another embodiment, the invention relates to a combination vaccine for protection against a pathogenic infection with PCV2 and Mhyo by intradermal administration.

The present invention pertains to a vaccine comprising in combination non-replicating immunogen of porcine circo virus type 2 and live attenuated PRRS virus for use in prophylactically treating an animal against an infection with porcine circovirus type 2 (PCV2) and an infection with PRRS virus by administration of the vaccine into the dermis of the animal.

The present invention is directed to a gram-negative bacterial host cell for vaccine use comprising a heterologous functional Actinobacillus pleuropneumoniae (APR) rfb gene cluster producing an APR O-anti-gen bound to the lipid A-core of the bacterial host cell and located on the bacterial host outer surface, and wherein the endogenous rib gene cluster of the bacterial host cell is not functional. The invention further pertains to compositions comprising said host cells, in particular vaccines, and corresponding uses in the prophylaxis and/or therapy of Actinobacillus pleuropneumoniae (APR) infections.

Vaccines for preventing or treating diabetes, obesity and complications thereof are provided. The vaccines comprise at least one active agent such as attenuated Porphyromonas gingivalis, inactivated Porphyromonas gingivalis, a subunit of Porphyromonas gingivalis, a recombinant or isolated immunogenic polypeptide or peptide from Porphyromonas gingivalis or a cDNA from Porphyromonas gingivalis.

Outer membrane vesicles from bacteria of the Burkholderia pseudomallei complex can be used as adjuvants in compositions and methods to potentiate the immune response to immunogens.

Methods of preparing influenza viruses having altered immunodominant epitopes in HA, e.g., having one or more residues in one or more of antigenic sites A-E in HA altered, and viral vectors, e.g., influenza virus VLPs or non-influenza viruses or VLPs thereof expressing or having influenza HAs with altered immunogenicity as a result of altered immunodominant epitopes therein are provided.

The present invention provides for immunogenic compositions and methods for producing an immunogenic composition with multiple immunity-inducing fractions of killed, whole-cell Streptococcus pneumoniae by selectively disrupting a whole cell bacterial preparation in such a manner that a soluble fraction that induces a primarily antibody response, and a cellular fraction that induces a primarily antibody-independent response, remain in the immunogenic composition.

The present invention relates to an influenza virus surface protein-derived recombinant hemagglutinin (HA) protein forming a trimer and use thereof, and more specifically to a recombinant vector for producing an influenza virus surface protein-derived HA protein forming a trimer, a transformant transformed by the recombinant vector, a method for producing an influenza virus surface protein-derived HA protein forming a trimer using the recombinant vector, an influenza virus surface protein-derived HA protein produced by the method, and the use thereof in preventing, ameliorating or treating influenza virus-infected disease.

Bordetella pertussis iron receptor proteins or portions thereof (e.g., one or more extracellular domains), alone or spliced into B. pertussis scaffold proteins (e.g., fimbrial or flagellin), are provided and can be used in acellular vaccines to protect against pertussis or other Bordetella diseases in humans and non-human mammals. In addition, Bordetella species grown under iron-starved conditions are provided and can be used in whole cell vaccines to protect against pertussis or other Bordetella diseases in humans and non-human mammals.

The present invention refers to a freeze-dried composition consisting of an isolated microorganism belonging to the Mycobacterium tuberculosis complex, preferably a M. tuberculosis clinical isolate, more preferably M. tuberculosis clinical isolate, characterized in that it comprises a PhoP− phenotype by the inactivation by a genetic deletion of the Rv0757 gene and the deletion of a second gene, Rv2930 (fadD26), that prevents PDIM production (PDIM− phenotype) (the MTB VAC strain), and sucrose and sodium glutamate as stabilizers or excipients. The present invention further refers to the reconstituted composition obtained by adding water, preferably sterilized water for injection, to the freeze-dried composition as well as uses thereof, in particular for use as a prophylactic agent to those at risk of infection with M. tuberculosis or those at risk of developing tuberculosis disease, or as secondary agents for treating infected tuberculosis patients.
