This invention provides kits, devices, and methods for the detection of antibodies that recognize one or more proteins and/or antigens from porcine reproductive and respiratory syndrome virus (PRRSV). The antibodies may be in a biological fluid of a PRRSV infected or at risk subject. The invention may be advantageously applied to both the diagnosis and prevention of PRRSV infection.

Embodiments of the present invention relate to an infectious bronchitis virus (IBV) and an immunogenic composition comprising an IBV, respectively, wherein the ORF 3a and/or the ORF 3b and/or the ORF 5a and/or the ORF 5b is inactivated. Furthermore, aspects of the present invention relate to methods for immunizing a subject comprising administering to such subject the immunogenic composition of the present invention. Moreover, embodiments of the present invention relate 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 embodiments of the present invention.

Immunogenic compositions containing a human immunodeficiency virus (HIV) gp140 protein, sorbitol, polysorbate 20, and histidine buffer are described. The described immunogenic compositions are advantageous in that they are stable at refrigerated temperature for extended periods of time, and are compatible with an adjuvant. Also described are methods of using the immunogenic compositions to induce an immune response against an HIV in a subject. The immunogenic compositions can be administered alone, or in combination with one or more additional HIV antigens, or one or more adenovirus vectors encoding the one or more additional HIV antigens.

The present invention relates to an adenoviral vector capable of encoding a virus-like particle (VLP), said VLP displaying an inactive immune-suppressive domain (ISD). The vaccine of the invention shows an improved immune response from either of both of the response pathways initiated by CD4 T cells or CD8 T cells.

A method of administering a pharmaceutical composition includes the step of administering a sterile unit of vaccine to the ocular mucosa. The vaccine can be made of DNA segments, RNA segments, messenger RNA live virus, or attenuated virus. The unit dosage can be about 20 to 70 microliters. The vaccine is suspended in a solution which closely matches the ocular tear film in terms of pH, osmolality and can be non-preserved and viscous. The pharmaceutical composition is delivered to the surface of the eye in sequential doses over a predetermined period of time to provide a total dosage for providing the vaccine to the patient.

Disclosed herein are methods and compositions related to therapy for cancer. More specifically, the disclosed methods and compositions are related to the use of smallpox vaccine to induce an effective anti-tumor immune response.

The present invention relates to the development and manufacturing of viral vaccines. In particular, the invention relates to the field of industrial production of viral vectors and vaccines, more in particular to the use of avian embryonic stem cells, preferably the EBx® cell line derived from duck embryonic stem cells, for the production of viral vectors and viruses. The invention is particularly useful for the industrial production of viral vaccines to prevent viral infection of humans and animals.

The invention provides various reverse genetics systems for producing segmented RNA viruses, wherein the systems do not require bacteria for propagation of all of their expression constructs.

This document relates to methods and materials for virotherapy. For example, this document provides methods and materials for treating cancer using a recombinant mumps virus as an oncolytic agent.

The present invention relates to an adenoviral vector capable of encoding a virus-like particle (VLP), said VLP displaying an inactive immune-suppressive domain (ISD). The vaccine of the invention shows an improved immune response from either of both of the response pathways initiated by CD4 T cells or CD8 T cells.
