M Hyo Multivalent Vaccine and Uses Thereof
The present invention relates to compositions or vaccines for combating Mycoplasma hyopneumoniae (M hyo), Porcine Circovirus type 2 (PCV2), and Porcine Reproductive and Respiratory Syndrome Virus (PRRSV) infections in animals and for increasing the ability of pigs to gain weight and/or improve death loss, methods of vaccination against the infections, and kits for use with such methods and compositions.
1 . A composition or vaccine comprising: i) an M hyo antigen, and ii) a porcine circovirus type 2 (PCV2) antigen, a Porcine Reproductive and Respiratory Syndrome Virus (PRRSV) antigen, or a combination thereof.
2 . The composition or vaccine of claim 1 , wherein the composition of vaccine comprises an M hyo antigen and a PCV2 antigen.
3 . The composition or vaccine of claim 1 , wherein the composition of vaccine comprises an M hyo antigen and a PRRSV antigen.
4 . The composition or vaccine of claim 1 , wherein the composition of vaccine comprises an M hyo antigen, a PCV2 antigen and a PRRSV antigen.
5 . The composition or vaccine of claim 1 , wherein the M hyo antigen is an inactivated M hyo.
6 . The composition or vaccine of claim 1 , wherein the PRRSV antigen is a modified-live and/or an inactivated PRRSV.
7 . The composition or vaccine of claim 1 , wherein the PCV2 antigen is an inactivated PCV2.
8 . The composition or vaccine of claim 1 , wherein the PRRSV antigen comprises an inactivated PRRSV comprising a polynucleotide encoding an ORF5 protein having at least 91% sequence identity to the sequence as set forth in SEQ ID NO:2, 3, 4, 5, 6, 7, 8, or 9.
9 . A composition or vaccine comprising one or more PRRSV antigens, wherein the PRRSV is a modified-live and/or an inactivated PRRSV.
10 . The composition or vaccine of claim 9 , wherein the PRRSV antigen comprises an inactivated PRRSV comprising a polynucleotide encoding an ORF5 protein having at least 91% sequence identity to the sequence as set forth in SEQ ID NO:2, 3, 4, 5, 6, 7, 8, or 9.
11 . The composition or vaccine of claim 9 , wherein the composition or vaccine comprises a modified-live PRRSV antigen and an inactivated PRRSV antigen.
12 . The composition or vaccine of claim 1 or 9 , wherein the composition or vaccine increases the ability of pigs to gain weight or improve death loss.
13 . The composition or vaccine of claim 1 or 9 , wherein the composition further comprises one or more pharmaceutically or veterinarily acceptable carrier, adjuvant, vehicle, or excipient.
14 . A method of vaccinating an animal or inducing an immunogenic or protective response in the animal against one or more pig pathogens, or increasing the ability of pigs to gain weight or improve death loss, comprising at least one administration of the composition or vaccine of claim 1 or 9 .
15 . The method of claim 14 , wherein the method comprises a prime-boost administration regimen.
16 . The method of claim 15 , wherein the method comprises a primary administration of a composition or vaccine comprising an M hyo antigen, a PCV2 antigen, and a PRRSV antigen and a boost administration of a composition or vaccine comprising a PRRSV antigen.
17 . The method of claim 16 , wherein the PRRSV antigen of the primary administration is a modified-live PRRSV, and wherein the PRRSV antigen of the boost administration is an inactivated PRRSV.
18 . A method of vaccinating an animal or inducing an immunogenic or protective response in the animal against one or more pig pathogens, or improve death loss, comprising at least one administration of the composition or vaccine of a modified-live PRRSV and an inactivated PRRSV.
19 . The method of claim 14 or 18 , wherein the animal is swine.
20 . A vaccination kit or set comprising one or more vaccine vials containing the composition or vaccine of claim 1 or 9 .
