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 ΔcapB), wherein the LVS ΔcapB 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 ΔcapB), wherein the LVS ΔcapB 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.
