Variants of human papilloma virus antigens
First Claim
1. An isolated variant human papillomavirus (HPV) protein able to elicit an immune response against HPV in a host animal but not being cell-transforming in said host animal, wherein said variant protein comprises a fusion protein comprising a first HPV E6 protein selected from the group consisting of full length E6 protein and non-full length deletion mutants thereof, and a second HPV E6 protein selected from the group consisting of full length E6 protein and non-full length deletion mutants thereof, and optionally a linker linking said first and second proteins.
