  • Publication number: 20240050552
    Abstract: The invention is directed to immunogenic compositions and method of treatment comprising a peptide or nucleic acid that encodes the peptide that induces an immune response in a mammal that is protective against infection by one or more pathogens. The peptide sequence contains multiple epitopes, wherein at least one epitope is a composite epitope which is a combination of two or more conserved epitopes of the pathogen wherein the amino acid sequence of the composite is not an amino acid sequence of the pathogen. In addition, the invention is directed to vaccines comprising the peptide or nucleic acid that encodes the peptide for treating and preventing an infection in mammals such as animals and humans.

  • Publication number: 20230226166
    Abstract: The invention relates to immunogenic compositions comprising an antigen obtained or derived from an antigenic epitope of one or more pathogens that induces an immune response in a mammal, an antigen obtained or derived from bacterial cell wall or viral material that induces an immune response in a mammal such as LTA, PNG or LPS, and a T cell stimulating antigen such as CRM. Preferably the immunogenic composition is a vaccine that is effective against a pathogenic infection or can generate antibodies that can be collected that are protective against infection by the pathogen. In addition, the invention relates to vaccines comprising antigens and to method for treating and preventing an infection.

  • Publication number: 20230201326
    Abstract: The invention is directed to portions of proteins of gram-positive bacteria, gram-negative, acid-fast bacteria (Mycobacteria, Staphylococcus) and/or virus (SARS-COV-2, Influenza), and antibodies reactive against these portions that can be formulated as immunogenic compositions and vaccines for the treatment and prevention of a microbial and/or viral infections. Preferably, compositions of the invention contain one or more portions of selected microbial and/or viral proteins that, upon administration to a subject, generate an effective cellular and/or humoral immune response, modulate immunity and a cytokine response. Effective responses involve an increased generation of antibodies that enhance immunity against an infection and promote an enhanced a phagocytic response. Monoclonal antibodies produced against these peptides enhance phagocytosis and killing of bacteria, viruses, and other microbes by phagocytic cells, and enhance clearance from the blood.

  • Publication number: 20220088166
    Abstract: The invention is directed to compositions and methods for stimulating, enhancing or modulating the immune system of a patient before or after infection by a pathogen, and in particular multidrug resistant (MDR) MTB and extremely drug resistant (XDR) MTB. Compositions of the invention contain non-naturally occurring antigens that generate an effective cellular and/or humoral immune response to MTB and/or antibodies that are specifically reactive to MTB antigens. The greater activity of the immune system generated by a vaccine of the invention increases generation of memory T cells that provide for a greater and/or extended response to an MTB infection. Responses involve an increased generation of antibodies that enhance immunity against MTB infection and promote an enhanced phagocytic response.
