  Purpose

This study is to assesss the safety and immunogenicity of vaccine based on Modified Vaccinia Ankara (MVA) expressing the 85A antigen (from Mycobacterium. tuberculosis). This vaccine is delivered intrdermally by a needle injection in healthy volunteers.

Primary Outcome Measures:
  • Local and systemic reactions will be monitored 30 and 60 minutes after administration.
  • A photograph of the injection will be taken at 48 hours and this injection site will be reviewed 7 days after each immunisation.
  • Blood will be taken: 1 week after the first vaccination, 1 week after the second vaccination and then at 4, 8, 12 and 24 weeks. The blood is used for a full blood count and biochemical screen.
  • Immunological assays are performed at all time points to determine vaccine imunogenicity (T cell responses are measured using an interferon-gamma Elispot assay).

Secondary Outcome Measures:
  • Immunological assays are performed at all time points to determine vaccine imunogenicity (T cell responses are measured using an interferon-gamma Elispot assay).
