Mosaic protein and nucleic acid vaccines against hepatitis C virus
View Patent ↗The invention relates to immunogenic compositions useful as HCV vaccines. Provided are HCV mosaic polypeptide and nucleic acid compositions which provide higher levels of T-cell epitope coverage while minimizing the occurrence of unnatural and rare epitopes compared to natural HCV polypeptides and consensus HCV sequences.
1. A multivalent HCV mosaic polypeptide composition comprising a set of polypeptides selected from the group consisting of the polypeptides of SEQ ID NOS: 42-44 and the polypeptides of SEQ ID NOS: 45-48.
2. The composition according to claim 1 , wherein one or more of the selected polypeptides are fragmented to present individual HCV proteins.
3. The composition according claim 1 , further comprising a pharmaceutically acceptable carrier.
4. The composition according to claim 1 , further comprising an adjuvant.
5. The composition according to claim 1 , further comprising a co-stimulatory molecule.
