Primary Outcome Measures:
  • Safety of the Vaccine. This will be determined by the degree and number of adverse events reported.

Secondary Outcome Measures:
  • Immunogenicity of this vaccine. It is expected that the vaccine will stimulate T cell responses, which will be measured by interferon –gamma Elispot assays.

Ages Eligible for Study:   18 Years to 45 Years
Genders Eligible for Study:   Male
Accepts Healthy Volunteers:   Yes

Inclusion Criteria:

  • Healthy adult male aged 18-45 years.
  • Normal medical history and physical examination. Minor physical ailments e.g. Fungal skin infections, will not be sufficient to define a physical examination as abnormal.
  • Normal urine dipstick, blood count, liver enzymes, and creatinine
  • Frequency <4 SFU per/well/3x105 PBMC as determined by ELISPOT with ESAT6/CFP-10 antigens and less than 100 SFU per/well/1x106 PBMC as determined by ELISPOT with PPD.
  • Mantoux negative (0.0 mm induration).
  • Normal Chest X-ray.
  • Willing to donate blood samples as required by the protocol

Exclusion Criteria:

  • Clinically significant history of skin disorder (eczema, psoriasis, etc.), allergy, immunodeficiency, cardiovascular disease, respiratory disease, endocrine disorder, liver disease, renal disease, gastrointestinal disease or neurological illness.
  • Any clinical evidence of immunosuppression such as oral candida, stomatitis, aphthous or septic ulceration, septic skin lesions or any clinical or laboratory evidence of infection or immunocompromise.
  • History of splenectomy
  • Haematocrit of less than 30%
  • Serum creatinine concentration >130mmol
  • Serum ALT concentration >80IU/L
  • Blood transfusion within one month of the beginning of the study
  • History of vaccination with any previous experimental poxvirus vaccine
  • Administration of any other vaccine or immunoglobulin within two weeks before or two weeks after vaccination.
  • Positive HIV antibody test, evidence of HBV (Hepatitis B vaccination is not an exclusion criteria)..
  • Current participation in another clinical trial, or within 12 weeks of this study
  • Any other finding which in the opinion of the investigators would increase the risk of an adverse outcome from participation in the trial.
  • Likelihood of travel away from the study area for the duration of the study
  • Untreated malaria infection
