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.

Described herein are novel vaccine compositions and methods for use thereof in inducing an immune response in a subject especially aged subjects. Specifically exemplified are vaccine compositions that include an antigen; a cyclic dinucleotide; soluble tumor necrosis factor (TNF); or a CD64 antibody or antibody fragment. Optionally, the vaccine composition comprises a TNF conjugated with a moDC targeting moiety in addition to or in place of TNF or CD64 antibody or antibody fragment, or both TNF and CD64 antibody or antibody fragment.

The present disclosure relates to nanoemulsion vaccine compositions and methods of making and using the same. The disclosed compositions and methods provide a means of treating, preventing, or protecting an individual from anthrax exposure or poisoning.

Bivalent immunogenic compositions against anthrax and plague are disclosed herein. One bivalent immunogenic composition comprises a triple fusion protein containing three antigens, F1 and V from Yersinia pestis and PA antigen from Bacillus anthracis fused in-frame and retaining structural and functional integrity of all three antigens. Another bivalent immunogenic composition comprises bacteriophage nanoparticles arrayed with these three antigens on the capsid surface of the bacteriophage nanoparticles. These bivalent immunogenic compositions are able to elicit robust immune response in a subject administered said the bivalent immunogenic compositions and provide protection to the subject against sequential or simultaneous challenge with both anthrax and plague pathogens.

The present disclosure provides adjuvanting systems comprising: (a) a polyI:C polynucleotide adjuvant; (b) a lipid-based adjuvant;(c) an amphipathic compound; and (d) a hydrophobic carrier. Also provided are vaccine compositions that are water-free or substantially free of water, which comprise the same components together with one or more antigens. The disclosure also provides uses for such compositions in inducing an antibody (humoral) and/or cell-mediated immune response and methods for their use in the treatment of a disease, disorder or ailment ameliorated by an antibody and/or cell-mediated immune response.

Disclosed is the hypolipidemic potential of Bacillus coagulans. More specifically the invention discloses the cholesterol lowering potential of Bacillus coagulans MTCC 5856 and therapeutic/biological indications thereof.

The present invention relates to a system and method for controlling peptide display valency on virus-like particles (VLPs), especially including MS2 VLPs. In this method, large amounts of wild-type and low quantities of single-chain dimer coat proteins may be produced from a single RNA. Valency is controlled in immunogen (vaccine) production by providing a system that allows the production of large amounts of wild-type and low quantities of single-chain dimer coating proteins from a single RNA, allowing facile adjustment of display valency levels on VLPs, especially MS2 VLPS over a wide range, from few than one-on average- to as many as ninety per particle. This facilitates the production of immunogens and vaccines, including VLPs exhibiting low valency. Nucleic acid constructs useful in the expression of virus-like particles are disclosed, comprised of a coat polypeptide of MS2 modified by insertion of a heterologous peptide, wherein the heterologous peptide is displayed on the virus-like particle and encapsidates MS2 niRNA. Nucleic acid constructs are also disclosed which are useful in the expression of virus-like particles comprised of a coat polypeptide of PP7 modified by insertion of a heterologous peptide, wherein the heterologous peptide is displayed on the virus-like particle and encapsidates PP7 mRNA.
