The present invention relates to a technology and method of priming of an immune response using invariant chain linked antigen, when these are used to prime a subsequent booster immunization using any suitable vacci.

Provided herein are immunogenic compositions comprising a recombinant modified vaccinia virus Ankara (MVA) comprising a nucleic acid sequence encoding a flagellin, and a nucleic acid sequence encoding a heterologous disease-associated antigen, wherein the immunogenic composition induces increased T-cell and antibody mediated immune responses specific for the heterologous disease-associated antigen when administered to a subject, e.g. a human subject, and related methods and uses.

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 invention is directed to a vaccine comprising: i) coxsackie B virus CBV1 and CBV2, and ii) at least one coxsackie B virus selected from CBV3, CBV4, CBV5 and CBV6. The CBVs are present in the vaccine in inactivated form, in the form of a component of the virus or as an antibody against the virus. The vaccine is effective in preventing and treating type 1 diabetes. So is an anti-coxsackie B virus composition provided.

The application discloses a method of immunising against Staphylococcus aureus infection comprising a step of administering to a human patient a single dose of an immunogenic composition comprising; (i) a Staphylococcus aureus ClfA protein or immunogenic fragment thereof at a dose of 5-50, 10-30, 5-15 or 20-40 μg and (ii) a pharmaceutically acceptable excipient; wherein the pH of the composition is pH 5.0-pH 8.0. The application further discloses an immunogenic composition comprising; (i) a S. aureus Type 5 capsular saccharide conjugated to a carrier protein, (ii) a S. aureus Type 8 capsular saccharide conjugated to a carrier protein, (iii) a ClfA protein or immunogenic fragment thereof, (iv) an alpha toxoid, and (v) a pharmaceutically acceptable excipient; wherein the pH of the immunogenic composition is pH 5.0-pH 8.0

The present invention aims to provide a vaccine pharmaceutical composition universally usable for induction of humoral immunity against various antigens and exerting a high antibody production inducing effect. The present invention relates to a vaccine pharmaceutical composition for inducing humoral immunity, including: an antigen; and an immunity induction promoter that is a bisphosphonate.

The present invention provides vaccine compositions and methods of producing such compositions. Other embodiments of the invention include methods of treating a pathogen infection, methods of vaccinating a subject against a pathogen infection, and methods for treating an antibiotic-resistance bacterial infection in a subject in need thereof. In further embodiments, the invention includes methods of decreasing the level of a pathogen in a subject having a pathogen infection, methods of increasing the surviving rate of a subject having a pathogen infection, methods of reducing the level of pain associated with a pathogen infection, and methods of reducing the level of distress associated with a pathogen infection in a subject in need thereof. Novel scaffold compositions and opsonin-bound or lectin-bound pathogen compositions, and uses thereof, are also provided herein.

Pre-conditioning a vaccine site with a potent recall antigen such as tetanus/diphtheria (Td) toxoid can significantly improve the lymph node homing and efficacy of tumor antigen-specific DC vaccines. Patients given Td had enhanced DC migration bilaterally and significantly improved survival. In mice, Td pre-conditioning also enhanced bilateral DC migration and suppressed tumor growth in a manner dependent on the chemokines CCL3 and CCL21 and Td-activated CD4.sup.+ T cells. Interference with any component of this axis markedly reduced Td-mediated DC migration and antitumor responses. Our clinical studies and corroborating investigations in mice suggest that pre-conditioning with a potent recall antigen represents a viable strategy to increase DC homing to lymph nodes and improve antitumor immunotherapy.

Vaccination methods to control PCV2 infection with different PCV2 subtypes are disclosed. Specifically, a PCV2 subtype b (PCV2b) ORF2 proteins or immunogenic compositions comprising a PCV2b ORF2 protein are used in a method for the treatment or prevention of an infection with PCV2 of a different subtype, the reduction, prevention or treatment of clinical signs caused by an infection with PCV2 of a different subtype, or the prevention or treatment of a disease caused by an infection with PCV2 of a different subtype.

The invention relates to helminthic parasite preparations and their use for treatment or prevention of GVHD in a subject that has undergone a transplant. The invention also related to helminthic parasite preparations and their use for prevention of GVHD in a subject prior to a transplant.
