Abstract: Embodiments of the invention include immunogenic compositions that comprise an attenuated recombinant Francisella tularensis subspecies holarctica Live Vaccine Strain (LVS) having a deletion in a polynucleotide encoding CapB (LVS ?capB), wherein the LVS ?capB expresses one or more antigens present on severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), Embodiments of the invention also include methods of immunizing a susceptible host against a pathogen comprising administering to the host a vaccine that comprises an attenuated recombinant Live Vaccine Strain lacking a polynucleotide encoding CapB (LVS ?capB), wherein the LVS ?capB expresses one or more antigens expressed by a severe acute respiratory syndrome coronavirus 2 (SAR8-CoV-2) polypeptide.

Abstract: A method of immunizing a susceptible host against a pathogen comprising administering to the host a vaccine that comprises an attenuated recombinant live vaccine strain lacking a polynucleotide encoding CapB (LVS ?capB), wherein the LVS ?capB expresses an antigen of at least one pathogen from Table 1; or administering to the host a vaccine that comprises an attenuated Listeria monocytogenes expressing the antigen of the pathogen from Table 1; or administering to the host a prime vaccine and a heterologous booster vaccine where the prime vaccine comprises an attenuated recombinant live vaccine strain lacking a polynucleotide encoding CapB (LVS ?capB), wherein the LVS ?capB expresses an antigen of at least one pathogen from Table 1 and the heterologous booster vaccine comprises an attenuated Listeria monocytogenes expressing the antigen of the pathogen from Table 1.
