Vaccines comprising cholesterol and CpG as sole adjuvant-carrier molecules
Described are vaccines having one or more antigens cholesterol and CpG. Aspects of the invention relate to the use of the vaccines of the invention for the treatment and/or prevention of human and animal disorders.
1. A vaccine comprising one or more antigens and an adjuvant, the adjuvant consisting of one or more isolated immunostimulatory oligonucleotides and cholesterol admixed together, and wherein the one or more isolated immunostimulatory oligonucleotides comprises a modified internucleotide linkage or a modified nucleoside base and wherein said adjuvant consisting of one or more isolated immunostimulatory oligonucleotides and cholesterol admixed together is the sole adjuvant in the vaccine.
2. The vaccine of claim 1 , wherein the one or more antigens are each independently, a microbial antigen, a self antigen, a tumor antigen, an allergen, or an addictive substance.
3. The vaccine of claim 2 , wherein the one or more antigens are each independently, a peptide, a peptide conjugated to a carrier protein, a peptide conjugated to a virus-like particle, a polypeptide, a recombinant protein, a purified protein, whole killed pathogen, live attenuated virus or viral vector expressing an antigen, live attenuated bacteria or a bacterial vector expressing an antigen, a polysaccharide, a polysaccharide conjugated to a carrier protein, a hapten, a hapten conjugated to a carrier protein or a small molecule.
4. The vaccine of claim 3 , wherein the antigen is of bacterial origin, viral origin or parasitic origin.
5. The vaccine of claim 4 , wherein a) the bacterial antigen is whole killed bacteria, live attenuated bacteria or bacterial purified proteins; or b) the viral antigen is whole killed virus, live attenuated virus or viral purified proteins.
6. The vaccine of claim 3 , wherein the carrier protein is a bacterial toxoid or derivative, Pseudomonas exotoxin, KLH or a virus-like particle.
7. The vaccine of claim 6 , wherein a) the bacterial toxoid is diphtheria toxoid, or a derivative thereof; or b) the virus-like particle is HBsAg, HBcAg, E. coli bacteriophage Qβ, Norwalk virus or influenza HA.
8. The vaccine of claim 2 , wherein a) the addictive substance is nicotine or a nicotine-like molecule; or b) the tumor antigen is one or more of survivin, Her-2, EFGRvIII, PSA, PAP or PMSA.
9. The vaccine of claim 3 , wherein the hapten conjugated to a carrier protein is nicotine or a nicotine-like molecule conjugated to diphtheria toxoid or a derivative thereof.
10. The vaccine of claim 1 , wherein the amount of cholesterol relative to the amount of antigen is 0.1 to 50 fold greater by weight, 1 to 10 fold greater by weight or equal in weight to the antigen.
11. A vaccine comprising one or more antigens and an adjuvant, the adjuvant consisting of an oil-containing emulsion, one or more isolated immunostimulatory oligonucleotides and cholesterol admixed together, and wherein the one or more isolated immunostimulatory oligonucleotides comprises a modified internucleotide linkage or a modified nucleoside base and wherein said adjuvant consisting of the oil-containing emulsion, said one or more isolated immunostimulatory oligonucleotides and cholesterol admixed together is the sole adjuvant in the vaccine.
12. The vaccine of claim 11 , further comprising a pharmaceutical carrier.
13. The vaccine of claim 11 , wherein the one or more antigens are each independently, a microbial antigen, a self antigen, a tumor antigen, an allergen, or an addictive substance.
14. The vaccine of claim 11 , wherein the one or more antigens are each independently, a peptide, a polypeptide, a recombinant protein, a purified protein, whole killed pathogen, live attenuated virus or viral vector expressing an antigen, live attenuated bacteria or a bacterial vector expressing an antigen, a polysaccharide, a polysaccharide conjugated to a carrier protein, a hapten, a hapten conjugated to a carrier protein, or a small molecule.
15. The vaccine of claim 14 , wherein the carrier protein is a bacterial toxoid or a derivative thereof, Pseudomonas exotoxin, KLH or a virus-like particle.
16. The vaccine of claim 15 , wherein a) the bacterial toxoid or derivative is diphtheria toxoid or a derivative thereof; or b) the virus-like particle is HBsAg, HBcAg, E. coli bacteriophage Qβ, Norwalk virus or influenza HA.
17. The vaccine of claim 11 , wherein the amount of cholesterol relative to the amount of antigen is 0.1 to 50 fold greater by weight, 1 to 10 fold greater by weight or equal in weight to the antigen.
18. The vaccine of claim 11 , wherein the one or more immune modulatory molecules are each independently, a TLR agonist, an antimicrobial peptide, a cytokine, a chemokine or a NOD ligand.
19. The vaccine of claim 18 , wherein the TLR agonists are each independently, an oligoribonucleotide (ORN), a small molecule that activates TLR 7 and/or TLR 8, or an oligodeoxynucleotide (ODN) that activates through TLR 9.
20. A method of inducing an antigen-specific immune response in a subject in need thereof, comprising administering a vaccine comprising one or more antigens and an adjuvant, the adjuvant consisting of an oil-containing emulsion, one or more isolated immunostimulatory oligonucleotides and cholesterol admixed together, in an effective amount to induce an antigen-specific immune response in the subject, and wherein the one or more isolated immunostimulatory oligonucleotides comprises a modified internucleotide linkage or a modified nucleoside base and wherein said adjuvant consisting of the oil-containing emulsion, said one or more isolated immunostimulatory oligonucleotides and cholesterol admixed together is the sole adjuvant in the vaccine.
