The present invention provides a fusion polypeptide that induces a humoral immune response and a cellular immune response to a virus, containing antigens or fragments thereof of the following (a) and (b), and having an oligomerization activity: (a) an antigen of the virus or a fragment thereof containing a B cell epitope conserved among subtypes of the virus; and (b) an antigen of the virus or a fragment thereof containing a T cell epitope conserved among subtypes of the virus (wherein the antigen(s) or the fragment(s) thereof of (a) and/or (b) have an oligomerization activity, or the fusion polypeptide further contains (c) a polypeptide having an oligomerization activity in addition to the antigens or the fragments thereof (a) and (b)).

A vaccine comprising a protein immunogen capable of stimulating a protective immune response against snake venom as well as spider and bee venoms. The DNA encoding the protein is disclosed. The protein can be expressed in both recombinant host cells. The protein is useful as a thermostable, parenteral administration anti venom vaccine protective against envenomation by diverse snake species, spiders and bees.

A method for synthesizing influenza virus-like particles (VLPs) within a plant or a portion of a plant is provided. The method involves expression of influenza HA in plants and the purification by size exclusion chromatography. The invention is also directed towards a VLP comprising influenza HA protein and plant lipids. The invention is also directed to a nucleic acid encoding influenza HA as well as vectors. The VLPs may be used to formulate influenza vaccines, or may be used to enrich existing vaccines.

An object of the present invention is to provide immunogenic compositions for protection against S. pneumoniae, in particular against S. pneumoniae serogroup 9, while limiting the number of conjugates. The present invention thereforerelates to new immunogenic compositions for use in pneumococcal vaccines and to vaccination of human subjects, in particular infants and elderly, against pneumoccocal infections using said immunogenic compositions.

This invention is directed to vaccine compositions and methods of using the same to prevent infection.

Provided herein are compositions comprising VHH conjugates and their uses in treating diseases.

Disclosed are Bifidobacterium pseudocatenulatum C-RAPO (KCTC13986BP) and Bifidobacterium bifidum ATT (KCTC13474BP) strains that have the effects of inhibiting sialoadenitis, which is a symptom of the Sjogren's syndrome, and inhibiting a reduction in saliva flow rate. Based on this, these strains can be used for prevention or treatment of Sjogren's syndrome and can be developed into food, health food and pharmaceuticals.

The present invention relates i.a. to an H52 IBV (infectious bronchitis virus) encoding for a heterologous S (spike) protein or fragment thereof. Further, the present invention relates to an immunogenic composition comprising said H52 IBV encoding for a heterologous S (spike) protein or fragment thereof. Furthermore, the present invention relates to methods for immunizing a subject comprising administering to such subject the immunogenic composition of the present invention. Moreover, the present invention relates to methods of treating or preventing clinical signs caused by IBV in a subject of need, the method comprising administering to the subject a therapeutically effective amount of an immunogenic composition according to the present invention.

The present document relates to methods and materials for treating a subject having an autoimmune disease.

Disclosed herein are compositions and methods related to mutant viruses, and in particular, mutant influenza viruses. The mutant viruses disclosed herein include a mutant M2 sequence, and are useful in immunogenic compositions, e.g., as vaccines. Also disclosed herein are methods, compositions and cells for propagating the viral mutants, and methods, devices and compositions related to vaccination.
