Primary Outcome Measures:
  • The occurance and severity of local and systemic side effects will be monitored. Vital signs and local reactions will be monitored at 30 and 60 minutes after each immunisation (and after 7 days).

Secondary Outcome Measures:
  • Immunogenicity will be measured: The induction of T cell responses (as measured by an interferon-gamma Elispot assay) will be performed on PBMCs from blood samples taken at the specified time points.
  • Proliferation assays and cytotoxic T cell assays will be performed on strong CD4+ and CD8+ responses respectively.
  • Antibody titres will be measured from frozen plasma samples.

Estimated Enrollment: 16
Study Start Date: May 2003
Estimated Study Completion Date: January 2005
