Abstract:
The present invention relates to novel plasmid constructs useful for the delivery of DNA vaccines. The present invention provides novel plasmids having a transcription cassette capable of directing the expression of a vaccine nucleic acid insert encoding immunogens derived from any pathogen, including fungi, bacteria and viruses. The present invention, however, is particularly useful for inducing in a patient an immune response against pathogenic viruses such as HIV, measles or influenza. Immunodeficiency virus vaccine inserts of the present invention express non-infectious HIV virus-like particles (VLP) bearing multiple viral epitopes. VLPs allow presentation of the epitopes to multiple histocompatability types, thereby reducing the possibility of the targeted virus escaping the immune response. Also described are methods for immunizing a patient by delivery of a novel plasmid of the present invention to the patient for expression of the vaccine insert therein. Optionally, the immunization protocol may include a booster vaccination that may be a live vector vaccine such as a recombinant pox virus or modified vaccinia Arbora vector.

424 932, 514 44, 4241861
Abstract:
This invention relates to a method of immunizing a vertebrate, comprising introducing into the vertebrate a DNA transcription unit which comprises DNA encoding a desired antigen or antigens. The uptake of the DNA transcription unit by a host vertebrate results in the expression of the desired antigen or antigens, thereby eliciting humoral or cell-mediated immune responses or both humoral and cell-mediated responses. The elicited humoral and cell-mediated immune response can provide protection against infection by pathogenic agents, provide an anti-tumor response, or provide contraception. The host can be any vertebrate, avian or mammal, including humans.
Compositions And Methods For Generating An Immune Response
We have developed DNA and viral vectors that can be used, alone or in combination, as a vaccine against one HIV clade, subtype, or recombinant form of HIV or against multiple HIV clades, subtypes, or recombinant forms. Moreover, the vectors can encode a variety of antigens, which may be obtained from one clade or from two or more different clades, and the antigens selected and/or the manner in which the vectors are formulated (e. g. , mixed) can be manipulated to generate a protective immune response against a variety of clades (e. g. , the clades to which a patient is most likely to be exposed; with the proportions of the components of the vaccine tailored to the extent of the patient's risk to a particular clade or clades).

US Classification:
4242081, 4353201, 536 235
Abstract:
The disclosure provides vectors encoding one or more HIV antigens and GM-CSF. Also provided are methods of inducing an immune response in a subject, methods of treating a subject having HIV, and methods of manufacturing a medicament for inducing an immune response that require the use of these vectors and vaccine inserts.
Mva Vectors Expressing Polypeptides And Having High Level Production In Certain Cell Lines
The present invention provides viral vectors, such as recombinant MVA vectors, that are capable of expressing one or more polypeptides, such as, e.g., HIV proteins or GM-CSF, in the cells of a human patient at relatively high levels and can also be produced in significant quantities in cultured cells. Also provided are methods for producing the viral vectors and pharmaceutical compositions containing them.
Researcher Dr. Harriet Robinson says the technology works by using only a tiny, harmless section of an Ebola virus cell to produce particles that trigger an immune response. "What you do is just use the parts of the virus that you need to produce virus-like particles and those are particularly good
