Hepatitis C Genotype 1 Mosaic Vaccines Are Immunogenic in Mice and Induce Stronger T-Cell Responses than Natural Strains

Broadly neutralizing antibodies protect against hepatitis C virus quasispecies challenge.
A major problem in hepatitis C virus (HCV) immunotherapy or vaccine design is the extreme variability of the virus. We identified human monoclonal antibodies (mAbs) that neutralize genetically diverse HCV isolates and protect against heterologous HCV quasispecies challenge in a human liver-chimeric mouse model. The results provide evidence that broadly neutralizing antibodies to HCV protect against heterologous viral infection and suggest that a prophylactic vaccine against HCV may be achievable
