In one aspect, a formulation comprising (a) an antibody that specifically binds an enterotoxigenic Escherichia coli (ETEC) or a molecule produced by an ETEC and (b) an antibody that specifically binds a norovirus (NV) or epitope thereof, is provided. In another aspect, a method of treating or preventing Travelers' diarrhea using the formulation is provided.

Provided herein are compositions and methods for generating an immunogenic response in humans. Further provided are methods for designing such compositions, e.g., for vaccines.

The present invention describes immunogenic compositions containing immunogenic polypeptides of Rabbit Haemorrhagic Disease Virus (RHDV), including immunogenic compositions containing antigens other than RHDV antigens, including antigens that may be used in immunization against pathogens that cause diarrheal diseases. Methods of eliciting an immune response with the immunogenic compositions as disclosed and methods of treating a RHDV infection are also described.

Two-component vaccine formulations and methods are contemplated where the vaccine has an adjuvant component and a therapeutic component. The therapeutic component comprises preferably a recombinant therapeutic virus encoding a therapeutic antigen while the adjuvant component comprises a non-host cell or immune stimulating portion thereof. Notably, use of the adjuvant component will result in significant uptake of the therapeutic component into immune competent cells, even in the absence of receptors for entry of the therapeutic component. In addition, such adjuvant also stimulates expression of the therapeutic antigen.

The present invention relates to single dose parenteral vaccine compositions comprising mixtures of monovalent Norovirus virus-like particles. Methods of conferring protective immunity against Norovirus infections in a human subject by administering such compositions are also disclosed.

The invention is in the field of vaccines, particularly vaccines for Noroviruses. In addition, the invention relates to methods of preparing vaccine compositions and methods of inducing and evaluating protective immune responses against Norovirus in humans, in particular, pediatric patients.

The present invention relates to vaccine compositions comprising Norovirus antigens and adjuvants, in particular, mixtures of monovalent VLPs and mixtures of multivalent VLPs, and to methods of conferring protective immunity to Norovirus infections in a human subject.

The present invention is directed to an artificial nucleic acid and to polypeptides suitable for use in treatment or prophylaxis of an infection with Norovirus or a disorder related to such an infection. In particular, the present invention concerns a Norovirus vaccine. The present invention is directed to an artificial nucleic acid, polypeptides, compositions and vaccines comprising the artificial nucleic acid or the polypeptides. The invention further concerns a method of treating or preventing a disorder or a disease, first and second medical uses of the artificial nucleic acid, polypeptides, compositions and vaccines. Further, the invention is directed to a kit, particularly to a kit of parts, comprising the artificial nucleic acid, polypeptides, compositions and vaccines.

The present invention is directed to methods and compositions for norovirus therapeutics, such as vaccines, and diagnostics.

The invention provides a norovirus genogroup I VP1 capsid protein having an amino acid sequence wherein the amino acid sequence stretch in the P domain Ala-Ala-Leu-Leu/Val-His-Tyr is modified to Ala-Ala-Leu-LeuNal-Arg/Lys-Tyr.
