Polyvalent, primary isolate nucleic acid compositions for inducing an immune response against HIV are disclosed. The compositions and methods described herein are for the use of a nucleic acid composition that encodes one or more different HIV envelope glycoproteins. The synthetic, codon-optimized DNAs encoding one or more HIV proteins are a combination of different nucleic acids, such as DNA plasmids, generated from primary isolate DNA of different HIV major group genetic clades and/or different proteins. HIV polypeptide compositions for inducing an immune response against HIV are also disclosed. Methods for using the polypeptide compositions before, at the same time as, and/or after administration of the DNA compositions are provided.

The present disclosure provides fusion proteins comprising Mycobacterium tuberculosis (Mtb) antigens, nucleic acid molecules encoding the same, vectors comprising nucleic acid molecules, compositions comprising the same, and methods of eliciting an immune response against tuberculosis.

This invention relates to novel fusion peptides and immunogenic compositions containing the fusion peptides useful in the control and prevention of tick infestations. The invention also relates to compositions comprising said fusion peptides, methods of vaccination against tick infestation using said fusion peptides and compositions, and kits for use with such compositions and methods.

The present invention provides safe, stable, efficacious, and cost-effective vaccines based on viral expression vectors that include a parainfluenza virus 5 (PIV5) genome including a heterologous nucleotide sequence expressing a heterologous polypeptide.

The present invention provides compositions, systems, kits, and methods for expression of one or more biomolecules in a subject, human or non-human mammal, (e.g., at therapeutic levels for the extended periods of time required to produce therapeutic effects). In certain embodiments, compositions, systems, kits, and methods are provided that comprise a first composition comprising polycationic structures (e.g., empty cationic liposomes, cationic micelles, cationic emulsions, or cationic polymers) and a second composition comprising expression vectors (e.g., non-viral expression vectors not associated with liposomes or other carriers) encoding one or more biomolecules of interest.

Disclosed are a composition for inducing immunity against an active ingredient and a method for preparing same, the composition comprising: a nucleic acid, a polypeptide, or a combination thereof as the active ingredient; a cationic compound; an amphiphilic block copolymer; and a polylactate, wherein the active ingredient is encapsulated in a nanoparticle structure formed by the amphiphilic block copolymer and the polylactate.

The present invention provides a vaccine for preventing and/or treating infections with human papillomavirus. The present invention relates to a lipid particle encapsulating a nucleic acid molecule capable of expressing the E6 and E7 antigens of human papillomavirus, wherein the lipid comprises a cationic lipid represented by general formula (Ia) or a pharmaceutically acceptable salt thereof:
