Abstract: The present invention relates to polynucleotides encoding antigens of the SARS-CoV-2 coronavirus spike protein and use thereof in the medical field as vaccines for the prevention and treatment of COVID-19 infection.

Abstract: Provided herein are non-plasmid derived DNA vaccines comprised solely of enzymatically produced amplicon expression vectors and their method of use to elicit antigen-specific immune responses in a subject. The enzymatically produced amplicon expression vectors may be specifically utilized as a DNA based cancer vaccine to express desired antigens or other immunogenic polypeptides within a subject to induce a specific anti-cancer antigen-specific immune response. The enzymatically produced amplicon expression vectors may also be utilized to express cancer-specific neoantigens.

Abstract: DNAs encoding rhesus monkey carcinoembryonic antigen (rhCEA) have been isolated, cloned and sequenced. The gene encoding CEA is commonly associated with the development of human carcinomas. The present invention provides compositions and methods to elicit or enhance immunity to the protein product expressed by the CEA tumor-associated antigen, wherein aberrant CEA expression is associated with a carcinoma or its development. This invention specifically provides adenoviral vector constructs carrying rhCEA and discloses their use in vaccines and pharmaceutical compositions for preventing and treating cancer.
