Disclosed herein is a vaccine comprising an antigen and one or more bimolecular adjuvant. Also disclosed herein are methods for increasing an immune response in a subject. The methods may comprise administering the vaccine to the subject in need thereof.

The invention provides compositions, kits and methods utilizing polypeptides having a viral alpha-helix heptad repeat domain in a stabilized -helical structure (herein also referred to as SAH). The compositions are useful for treating and/or preventing viral infections. The invention is based, at least in part, on the result provided herein demonstrating that viral hydrocarbon stapled alpha helical peptides display excellent proteolytic, acid, and thermal stability, restore the native alpha-helical structure of the peptide, are highly effective in interfering with the viral fusogenic process, and possess superior pharmacokinetic properties compared to the corresponding unmodified peptides.

Disclosed herein is a vaccine comprising an antigen and one or more bimolecular adjuvant. Also disclosed herein are methods for increasing an immune response in a subject. The methods may comprise administering the vaccine to the subject in need thereof.

The present invention relates to a vector(s) containing and expressing an optimized HIV EnvF gene, methods for making the same and cell substrates qualified for vaccine production which may comprise vector(s) containing optimized HIV genes.

Methods are disclosed for inhibiting a HIV infection in a subject. These methods include administering to the subject an effective amount of a recombinant gp120 protein comprising a deletion of HIV-1 Envelope residues 137-152 according to the HXBc2 numbering system, or a nucleic acid molecule encoding the recombinant gp120 protein, wherein the recombinant gp120 protein elicits an immune response to HIV-1. The methods also include administering to the subject an effective amount of a SAMT-247 microbicide.

The invention provides methods and compositions for eliciting broad immune responses to HIV envelope proteins. The methods include use of nucleic acids constructs that encode conserved elements of HIV Env to induce immune responses.

The subject invention concerns methods and materials for inducing an immune response in an animal or person against an immunodeficiency virus, such as HIV, SIV, or FIV. In one embodiment, a method of the invention comprises administering one or more antigens and/or immunogens to the person or animal wherein the antigen and/or immunogen comprises one or more evolutionarily conserved epitopes of immunodeficiency viruses. In one embodiment, the epitope is one that is conserved between HIV and FIV.

Methods for inducing an immune response against Human Immunodeficiency Virus (HIV) in HIV-infected subjects undergoing antiretroviral therapy (ART) are described. The methods include administering an adenovirus vector primer vaccine and a modified vaccinia virus (MVA) vector booster vaccine encoding mosaic HIV antigens.

The present invention relates to genetically stable replication competent Sendai virus vector(s) containing optimized HIV genes, methods for making the same and cell substrates qualified for vaccine production which may comprise genetically stable replication competent Sendai virus vector(s) containing optimized HIV genes.

The invention provides compositions, methods, and kits for the treatment or prevention of viral infections. The polyvalent (e.g., 2-valent) vaccines described herein incorporate computationally-optimized viral polypeptides that can increase the diversity or breadth and depth of cellular immune response in vaccinated subjects.
