The present invention provides compositions and methods of inducing an immune response in a subject in need thereof, comprising administering to the subject an immunologically-effective amount of a livevector comprising a heterologous antigen from a pathogen, wherein the heterologous antigen comprises an outer membrane protein, an antigenic fragment thereof or a variant thereof, wherein the antigen is delivered to a mucosal tissue of the subject by an outer membrane vesicle.

There are provided compositions and methods for prevention or treatment of(SP)-associated diseases. More specifically, there are provided recombinant lipidated fusion proteins comprising pneumococcal surface antigen A (PsaA), the recombinant lipidated fusion proteins comprising, from N-terminus to C-terminus, the N-terminal native lipid signal peptide of PsaA and the C-terminal structural gene for PsaA. Methods of inducing broad spectrum mucosal immunity against SP comprising administering a vaccine comprising recombinant lipidated fusion proteins are also described.

Lipidatedantigen compositions, methods of preparation and use

Disclosed is the use of fluorinated cyclic dinucleotides and pharmaceutically acceptable salts thereof as an adjuvant for the preparation of an oral vaccine. Further disclosed is the use of fluorinated cyclic dinucleotides and pharmaceutically acceptable salts thereof for enhancing the immune response to an orally administered vaccine.

Use of fluorinated cyclic dinucleotides as oral vaccine adjuvants

The invention relates to antibodies specific to serum albumins. More specifically, the invention relates to camelid single domain antibodies and pentabodies binding to serum albumins of various species with various affinities.

BSA-specific antibodies

A pharmaceutical composition for treating or preventing a Th2-mediated disease or disorder includes live, killed or attentuatedor its components. Thecells may be LVS cells. Administration of an effective amount may prevent or reduce bronchoconstriction or allergic airway inflammation through a T-helper cell (Th) 1-mediated suppression of an ongoing Th2 response mechanism.

[object Object]

The invention provides non-replicating compositions, and methods for the delivery of these compositions containing pharmaceuticals, biologically relevant molecules, and/or antigens to the host, by administration via a mucosal route such as the intranasal. This invention provides non-replicating vaccine compositions and methods for the delivery of antigens in these vaccine compositions comprising an antigen and a self-adjuvanting carrier, useful for inducing antigen-specific mucosal and systemic immune responses in the host upon immunization via a mucosal route such as intranasal. The vaccine compositions comprise multivalent cations in association with a plurality of spherical archaeal polar lipid aggregates containing aqueous compartments, the AMVAD structure, formed by the interaction of archaeosomes and antigen(s) with multivalent cations such as Ca, wherein the AMVAD structure acts as a self-adjuvanting carrier for the antigen(s) in the vaccine composition. Certain advantageous immune responses can also be elicited with the subject compositions.
