Abstract: The present invention relates to immunological compositions comprising sulpholipo-cyclodextrin (SL-CD) and, saponin or Quil A, and optionally at least one antigen. The invention relates to methods and immunological compositions comprising at least one antigen, which may be a veterinary antigen. The veterinary antigen in the methods and immunological compositions of the invention may be a bovine antigen. The invention relates to methods and immunological compositions comprising bovine ephemeral fever virus (BEFV), bovine herpesvirus 1 (IBR) or bluetongue virus (BTV). The invention comprises methods for eliciting an immune response against BEFV, IBR, or BTV in an animal, which comprises administering to the animal a composition of the invention. In the invention, particularly the immune response is a protective immune response. The invention comprises a method for preparing an immunological composition comprising adding Quil A to a virus.

Abstract: The invention relates to vaccines which are suitable for the prevention of clostridial diseases of sheep (and lambs), providing an effective immunity for up to a year or more following a single injection or dose.

Abstract: A class of carrier molecules which when covalently linked to an immunogen enhances the host's immune response to that immunogen, regardless of whether the complex of carrier and immunogen is administered parenterally, enterally, or orally to the host. Also provided are processes for production of the complexes, as well as hybrid DNA sequences encoding the complexes, recombinant DNA molecules bearing the hybrid DNA sequences, transformed hosts and vaccines comprising the complexes, and methods for production of the vaccine.
