Methods for inducing an immune response
The present invention relates to methods for inducing an immune response, in particular methods for inducing an immune response against mycobacterial infections or disease comprising (i) at least one administration of a polypeptide Rv1196 related antigen and at least one administration of an adenovirus encoding a Rv1196 related antigen or (ii) at least one administration of a polypeptide Rv0125 related antigen and at least one administration of an adenovirus encoding a Rv0125 related antigen. Associated compositions, adenoviral constructs and polynucleotide sequences are also provided.
1. A method for inducing an immune response comprising a T cell response in a subject comprising:
administration of a chimpanzee adenovirus encoding a Rv1196 related antigen comprising SEQ ID NO: 1, followed by administration of a polypeptide Rv1196 related antigen to the subject, wherein the polypeptide Rv1196 related antigen is provided in a composition which also comprises an adjuvant.
2. The method of claim 1 wherein the adjuvant comprises a Toll Like Receptor (TLR) agonist and/or an immunologically active saponin.
3. The method of claim 1 wherein the adjuvant comprises 3-O-deacylated monophosphoryl lipid A (3D-MPL).
4. The method of claim 1 wherein the adjuvant comprises QS21.
5. The method of claim 1 wherein the chimpanzee adenovirus is a ChAd3.
6. The method of claim 1 wherein the chimpanzee adenovirus is a ChAd63.
7. The method of claim 1 , wherein the Rv1196 related antigen comprises SEQ ID NO: 6.
8. The method of claim 1 , wherein the composition in which the polypeptide Rv1196 related antigen provided is substantially free of a non-human simian adenovirus encoding the Rv1196 related antigen.
9. The method of claim 1 , wherein the composition in which the polypeptide Rv1196 related antigen provided does not comprise a non-human simian adenovirus encoding the Rv1196 related antigen.
