The present invention is drawn to new oral live canine parainfluenza virus vaccines and related multivalent vaccines. Methods of using the vaccine alone or in combination with one or more other protective immunogens in multivalent vaccines are also provided.

A vaccine composition for intranasal administration includes a Bordetella pertussis antigen, and an effective adjuvant amount of a high molecular weight glucose polymer. The high molecular weight glucose polymer may be a beta-glucan. The Bordetella pertussis antigen may be an extracellular toxin, an adhesion protein, an outer membrane protein, a receptor protein, a fragment thereof, or a mixture thereof.

The present application relates to triterpene glycoside saponin-derived adjuvants, syntheses thereof, and intermediates thereto. The application also provides pharmaceutical compositions comprising compounds of the present invention and methods of using said compounds or compositions in the treatment of and immunization for infectious diseases.

Disclosed are methods and compositions related to the use cannabinoids as adjuvants for the accelerated induction and production of an antibody based immune response.

The present invention relates to the fields of medical microbiology and vaccines. In particular the invention relates to a process wherein the spontaneous release of bacterial outer membrane vesicles (OMV) of Gram-negative bacteria is stimulated by application of a dissolved oxygen tension (DOT) that is higher than a physiological DOT. The thus produced OMVs are for use in vaccines. The invention further relates to OMV obtainable by said process, and to a pharmaceutical composition comprising such OMV. The present invention further relates to the use of OMV of the present invention as a medicament in particular for use in a method for eliciting an immune response.

The present invention relates to a method of preparing a live attenuated vaccine by irradiation and a live attenuated vaccine composition prepared by the same, and more particularly, a method of preparing a live attenuated vaccine by irradiation including irradiating a pathogenic microorganism with a dose of 0.5 to 2 kGy of radiation per single radiation six to fifteen times; and a live attenuated vaccine composition including a pathogenic microorganism attenuated to not be revertant to a wild type by generation of at least one mutation of nucleotide insertion and nucleotide deletion by irradiation.

A system including a vial and methods of its use to provide a lyophilized cake removable from the vial without cracking or breaking.

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.

This invention relates to a method of treating a dog for canine diseases comprising administering to the dog therapeutically effective amounts of a vaccine, wherein the vaccine comprises viral antigens, a bacterin, or both, and wherein the vaccine is administered subcutaneously or orally according to the schedules provided herein.

The present invention relates to Toll-Like Receptor 2 (TLR2) agonists, in particular, to TLR2-activating lipoproteins, and more particularly to TLR2-activating lipopeptides derived from the bacteria Bordetella pertussis. The invention further extends to the use of said TLR2-activating lipoproteins as a therapeutic or as part of a vaccine composition in the treatment and prevention of infectious diseases, cancer or allergic diseases.
