In particular, the invention provides virus-like particles comprising at least one composite polypeptide. Such virus-like particles have antigenic epitopes of two or more circulating strains of a non-enveloped virus and produce an increase in antisera cross-reactivity to one or more circulating strains of the non-enveloped virus. Methods of making composite virus-like particles and vaccine formulations comprising composite virus-like particles are also disclosed.

Abstract: The plant-based production of a therapeutic antibody against West Nile Virus is disclosed.

Abstract: This invention relates to formulations which contain at least one active peptide intended to be used for prevention or treatment of a condition in an animal or human. Said active peptide has been expressed in a system that improves the conservation of those properties essential to the prophylactic or therapeutic effect of said peptide before and after delivery to an animal or human and until the peptide delivers its activity at the effector site within said animal or human. The invention is particularly relevant to formulations of oral or mucosal vaccines or biopharmaceuticals. The active peptide of the formulation is recombinantly expressed in cells or whole animals. In a preferred embodiment of this invention the active polypeptide of the formulation has been recombinantly expressed in insect cells or whole insect larvae.

Abstract: Nucleic acid oligomeric sequences and in vitro nucleic acid amplification and detection methods for detecting the presence of HAV RNA sequences in samples are disclosed. Kits comprising nucleic acid oligomers for amplifying and detecting HAV nucleic acid sequences are disclosed.

Abstract: Chimeric flaviviruses that are avirulent and immunogenic are provided. The chimeric viruses are constructed to contain amino acid mutations in the nonstructural viral proteins of a flavivirus. Chimeric viruses containing the attenuation-mutated nonstructural genes of the virus are used as a backbone into which the structural genes of a second flavivirus strain are inserted. These chimeric viruses elicit pronounced immunogenicity yet lack the accompanying clinical symptoms of viral disease. The attenuated chimeric viruses are effective as immunogens or vaccines and may be combined in a pharmaceutical composition to confer simultaneous immunity against several strains of pathogenic flaviviruses.

Abstract: Described herein are recombinant RVF viruses comprising deletions in one or more viral virulence genes, such as NSs and NSm. The recombinant RVF viruses, generated using a plasmid-based reverse genetics system, can be used as vaccines to prevent infection of RVF virus in livestock and humans. As described herein, the recombinant RVF viruses grow to high titers, provide protective immunity following a single injection and allow for the differentiation between vaccinated animals and animals infected with wild-type RVF virus.

Abstract: Methods of increasing diversity in cytomegalovirus vaccines through the selection of cell type in which the virus is propagated, and the use of cytomegalovirus produced by those methods in the development of vaccine compositions, are disclosed. Vaccine compositions comprising CMV isolated from epithelial cells are also disclosed.

Abstract: The invention relates to a truncated L1 protein of the Human Papillomavirus Type 16, a virus-like particle consisting of the protein, a vaccine comprising said virus-like particle, and the use of the vaccine in the prevention of cervical cancer.

Abstract: The present invention pertains to a method for keeping an immunogenic composition available for administration to an animal, wherein said composition comprises an antigen and an emulsion which is a single emulsion at a first temperature below a body temperature of the animal and which emulsion reverses at a second temperature between the first temperature and the body temperature, said method comprising providing the composition, freezing the composition, and storing the frozen composition until it is needed for administration to the animal. The invention also pertains to a method for testing an immunogenic composition, and an immunogenic composition, optionally in combination with specific instructions for storing the composition.

Abstract: The invention relates to generating a vaccine based on immunogens from viral particles that initially have replication competency but are then inactivated by chemical, biophysical or other methods. The components of this vaccine may be a non-HIV enveloped virus that contains and expresses a gene related to the HIV Envelope gene such that the Envelope protein is expressed on the surface of viral particles. These viral particles may be further treated to reduce their replication competency. The vaccine further may contain components to improve its immunogenicity, tolerability, stability and ease of manufacture.
