NCT01296451

Brief Summary

The study is aimed at assessing the safety of AdCh3NSmut and the new candidate vaccine MVA-NSmut when administered sequentially, or alone, to healthy volunteers and patients with hepatitis C virus infection The study also aims at assessing the cellular immune response generated by AdCh3NSmut and MVA-NSmut administered as mentioned above.

Outcome Measures

Primary Outcomes (1)

  • Number of participant with adverse events, type and severity of adverse events

    To assess the safety of new hepatitis C vaccine candidates, AdCh3NSmut (and the improved version AdCh3NSmut1) and MVA-NSmut when administered to healthy volunteers and to HCV infected patients. The specific endpoints for safety will be actively collected data on adverse events.

    Different time frames depending on study groups

Secondary Outcomes (1)

  • Immunogenicity
