Foot-and-mouth disease vaccine
Compositions for prevention of Foot and Mouth Disease (FM D) are provided, comprising an antigen component in the amount equivalent to 0.5-20 μg FM D virus and an adjuvant component comprising oil, an immunostimulatory oligonucleotide, and a polycationic carrier. Methods of using the composition, as well as the methods of reducing FM D persistence are also provided.
1. A method of herd management, comprising administering to each member in said herd the immunogenic composition wherein said composition comprises:
a) antigen component comprising between about 8 μg and 10 μg of FMD (Foot-and-Mouth Disease) virus composition per dose;
b) an emulsion containing an oil;
c) 75-200 μg of a CpG-containing immunostimulatory oligonucleotide per dose;
d) 75-200 mg of a polycationic carrier per dose, and
wherein further, upon suspected contact with FMD infection, the vaccinated members of said herd are not slaughtered.
2. A method of herd management, comprising administering to each member in said herd the immunogenic composition wherein said composition comprises:
a) antigen component comprising between about 8 μg and 10 μg of FMD (Foot-and-Mouth Disease) virus composition per dose;
b) an emulsion containing an oil;
c) 75-200 μg of a CpG-containing immunostimulatory oligonucleotide per dose;
d) 75-200 mg of a polycationic carrier per dose, and
wherein further, upon suspected contact with FMD infection, the vaccinated members of said herd are quarantined for 0-30 days.
3. A method of herd management, comprising administering to each member in said herd the immunogenic composition wherein said composition comprises:
a) antigen component comprising between about 8 μg and 10 μg of FMD (Foot-and-Mouth Disease) virus composition per dose;
b) an emulsion containing an oil;
c) 75-200 μg of a CpG-containing immunostimulatory oligonucleotide per dose;
d) 75-200 mg of a polycationic carrier per dose, and
wherein further, upon suspected contact with FMD infection, the vaccinated members of said herd are moved beyond the infected premises.
4. The method according to claim 1 , wherein the vaccinated members of the herd are not slaughtered and are quarantined for 0-30 days.
5. The method according to any one of claims 1 - 3 , wherein the FMD virus composition is prepared by hollow fiber filtration.
6. The method according to any one of claims 1 - 3 , wherein the polycationic polymer is diethylaminoethyl (DEAE) Dextran.
7. The method according to claim 6 , wherein the immunostimulatory oligonucleotide comprises CpG.
8. The method according to claim 7 , wherein the immunostimulatory oligonucleotide comprises at least 15 contiguous nucleotides of SEQ ID NO: 8.
9. The method according to claim 8 , wherein the FMD virus composition comprises a DIVA (differentiating infected from vaccinated animals) marker.
10. The method according to claim 9 , wherein said DIVA marker comprises at least one of a mutated 3B or a mutated 3D protein.
11. The method according to claim 10 , wherein the oil is a light mineral oil.
12. The method according to claim 11 , wherein oily phase comprises 50.01%-55% v/v of the composition.
13. The method according to any one of claims 1 - 3 , wherein the FMD virus composition comprises a DIVA marker.
14. The method according to claim 13 , wherein said DIV marker comprises at least one of a mutated 3B or a mutated 3D protein.
15. The method according to claim 14 , wherein said FMD virus composition is a preparation of FMD virus Cruzeiro strain.
16. The method according to claim 15 , wherein said FMD virus Cruzeiro strain comprises a heterologous capsid protein.
17. The method according to claim 16 , wherein said heterologous capsid protein is from a strain selected from Asia1, Turkey06, O1Campos, C3Indaial, and A2001-Argentina.
18. The method according to claim 16 , wherein the polycationic polymer is diethylaminoethyl (DEAE) Dextran.
19. The method according to claim 18 , wherein the immunostimulatory oligonucleotide comprises CpG.
20. The method according to claim 19 , wherein the immunostimulatory oligonucleotide comprises at least 15 contiguous nucleotides of SEQ ID NO: 8.
21. The method according to claim 20 , wherein the oil is a light mineral oil.
22. The method according to claim 21 , wherein oily phase comprises 50.01%-55% v/v of the composition.
