IL-12 an adjuvant for bordetella pertussis vaccines

Abstract

This invention provides a composition of at least one Bordetella antigen and an effective adjuvant amount of interleukin-12 (IL-12), and uses thereof as a vaccine against Bordetella infection. Methods for using IL-12 as an adjuvant in combination with vaccines against Bordetella are also provided.

1 - 43 . (canceled)  
     
     
         44 . A vaccine composition against  Bordetella  comprising at least one  Bordetella  antigen and an effective adjuvant amount of interleukin-12, wherein the composition is capable of eliciting a Th1 immune response.  
     
     
         45 . A vaccine composition comprising at least one  Bordetella  antigen and an effective adjuvant amount of interleukin-12, wherein the composition is capable of stimulating IFN-γ production in a host immunized with the composition.  
     
     
         46 . The composition of  claim 44  or  45 , wherein the at least one antigen is a  Bordetella pertussis  antigen.  
     
     
         47 . The composition of  claim 46 , wherein the at least one antigen is chosen from lipopolysaccharide, pertussis toxin, filamentous hemagglutinin, and pertactin.  
     
     
         48 . The composition of  claim 46 , wherein the at least one antigen is adsorbed to alum.  
     
     
         49 . The composition of  claim 44  or  45 , wherein the at least one  Bordetella  antigen is encoded by a polynucleotide capable of expressing the at least one  Bordetella  antigen in vivo.  
     
     
         50 . The composition of  claim 44  or  45 , wherein the interleukin-12 is encoded by a polynucleotide capable of expressing an effective adjuvant amount of interleukin-12 in vivo.  
     
     
         51 . A method for preventing, treating, or ameliorating infection by  Bordetella  in a host comprising administering to the host the composition of  claim 44  or  45 .  
     
     
         52 . A method for eliciting an immune response against  Bordetella  comprising administering simultaneously a first composition comprising at least one  Bordetella  antigen and a second composition comprising an effective adjuvant amount of interleukin-12.  
     
     
         53 . The method of  claim 52 , wherein the at least one antigen is a  Bordetella pertussis  antigen.  
     
     
         54 . The method of  claim 53 , wherein the at least one antigen is chosen from lipopolysaccharide, pertussis toxin, filamentous hemagglutinin, and pertactin.  
     
     
         55 . The method of  claim 53 , wherein the at least one antigen is adsorbed to alum.  
     
     
         56 . The method of  claim 52 , wherein the at least one antigen is administered as a polynucleotide capable of expressing the at least one antigen in vivo.  
     
     
         57 . The method of  claim 52 , wherein the interleukin-12 is administered as a polynucleotide capable of expressing interleukin-12 in vivo.  
     
     
         58 . A method for stimulating clearance of  Bordetella  from a host comprising administering a composition comprising at least one  Bordetella  antigen and an effective adjuvant amount of interleukin-12.  
     
     
         59 . The method of  claim 58 , wherein the at least one antigen is a  Bordetella pertussis  antigen.  
     
     
         60 . The method of  claim 59 , wherein the at least one antigen is chosen from lipopolysaccharide, pertussis toxin, filamentous hemagglutinin, and pertactin.  
     
     
         61 . The method of  claim 58 , wherein the at least one antigen is adsorbed to alum.  
     
     
         62 . The method of  claim 58 , wherein the at least one antigen is administered as a polynucleotide capable of expressing the at least one antigen in vivo.  
     
     
         63 . The method of  claim 58 , wherein the interleukin-12 is administered as a polynucleotide capable of expressing interleukin-12 in vivo.
