Abstract: Provided are modified bacteria and derivatives thereof that express nucleotide sequence encoding an antigen of a viral family selected from the group comprising Retroviridae (e.g., HIV, including a HIV Fusion Peptide antigen), Orthomyxoviridae, Paramyxoviridae, Arenaviridae, 5 Filoviridae, and/or Coronaviridae (e.g., an SARS-CoV, SARS-CoV-2 Fusion Peptide, and/or PEDV). In some embodiments, the bacterium has a reduced genome and induces an enhanced immune response against the viral antigen of interest when administered to a subject. In some embodiments, the viral (e.g., SARS-CoV, 10 SARS-CoV-2, PEDV, and/or HIV) antigen is expressed on a surface of a bacterium. Also provided are method for producing antibodies against viral antigens, vaccine compositions, methods for vaccinating subjects, methods for treating viral infections in subjects, and expression vectors for expressing viral antigens including but not limited to coronavirus (e.g.

Abstract: The present invention provides thin-film forming compositions comprising an antiseptic (e.g., povidone iodine, chlorhexidine, or octenidine), a non-aqueous solvent, and a film-forming material dissolved in the non-aqueous solvent, wherein the composition yields a continuous and flexible protective film upon substantial removal of the solvent. The compositions are useful for the treatment and prevention of infections in wounds, ulcers (e.g., decubitus ulcers and stasis ulcers), cuts, or burns, or against infections from bacterial, mycobacterial, viral, fungal, or amoeba causes, as well as for prevention of such infections in appropriate clinical settings (e.g., as liquid bandages or dressings). Additionally, the compositions of this invention are also useful for the treatment of infections and as a disinfectant skin preparation for pre- and/or post-surgical operations.
