The invention pertains to a vaccine for use in protecting a pig against an infection with porcine endemic diarrhea virus (PEDV), the vaccine comprising non-live PEDV antigen and a non-metabolizable oil containing adjuvant, wherein the total amount of oil in the vaccine is less than 50% v/v, by administration of a dose of the antigen corresponding to at least 3.0E6 TCID50 killed whole PEDV. The invention also pertains to a method of protecting a pig against an infection with porcine endemic diarrhea virus.

Vaccines of preferential administration via mucous membranes, for the control of viral diseases generated by infectious agents that use heparan sulfate (HS) as a cellular receptor consisting of an immunogenic formulation for veterinary use, comprising an antigen whose cellular receptor is heparan sulfate (HS), a vehicle for oral, intranasal or parenteral administration, wherein said vehicle corresponds to D-glucosamine and functionalized N-acetyl-D-glucosamine biopolymers, with sulfur atoms, and/or functionalized chitosan biopolymer, with sulfur atoms, and where the antigen is microencapsulated by said types of functionalized biopolymers.

Vaccine compositions including a yeast comprising an immunostimulatory polypeptide and optionally an antigenic polypeptide are provided herein. The immunostimulatory polypeptide and the antigenic polypeptide are expressed or displayed on the surface of the yeast vaccine composition. Methods of using the vaccine composition to vaccinate subjects are also provided.

A vaccine composition includes a porcine epidemic diarrhea virus (PEDV) S1 spike protein having an amino acid sequence of SEQ ID NO: 1, and an inactivated porcine epidemic diarrhea virus (PEDV). The vaccine composition is used in a method of preventing PEDV infection in swine, whereby systemic Immunoglobulin G (IgG), Immunoglobulin A (IgA) and neutralizing antibody may be successfully induced by the vaccine composition, hence providing sufficient immune protection against PEDV.

The invention relates to medicine and veterinary medicine, and more specifically to pharmacology, and can be used to prevent viral infections caused be RNA viruses that have a lipid capcid. An agent for prevention viral infections comprises viral material from RNA viruses that have a lipid capcid and stabilized colloidal selenium at a 1:1 ratio. The viral material from RNA viruses has titres of 6.0-8.0 lg TCD.sub.50/ml. To obtain colloidal selenium having particle sizes from 10 to 15 nm the colloidal selenium is stabilized with polyethylene glycol, and for colloidal selenium having particle sizes from 20 to 40 nm, the colloidal selenium is stabilized with cysteine.

The present invention is directed to novel vaccine delivery platform based on the Orf virus (ORFV) genome, which carry heterologous antigens, methods of making and methods of using the same for prevention of infections, diseases, and other conditions in animals.

The present disclosure provides vaccines or immunogenic compositions against clinical signs, symptoms, and losses attributable to or caused by infection with PEDV and/or ETEC. Antigenic epitopes from PEDV and ETEC are used to construct an immunogenic composition, preferably in the form of a multi-epitope fusion antigen or as a live strain through E. coli.
