Eligibility Criteria

Age18 Years - 50 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64)

You may qualify if:

  • Healthy adults aged 18 to 50 years
  • Resident in or near Dakar for the duration of the study
  • Willingness to allow the investigators to discuss the volunteer's medical history with the volunteer's HIV lead physician
  • Willing to use effective contraception throughout duration of study (if female)
  • HIV antibody positive; diagnosed at least 6 months previously
  • CD4 count \>300
  • Arm 1: HIV viral load not \>100,000 copies per millilitre
  • Arm 2: Undetectable HIV viral load
  • Written informed consent

You may not qualify if:

  • Any clinically significant abnormal finding on screening biochemistry or haematology blood tests or on urinalysis
  • Group 1 only: Any ARV therapy within the past 6 months
  • Previous history of TB disease and/or treatment
  • Any AIDS defining illness
  • Group 1: CD4 count nadir \<300
  • Group 2: CD4 count nadir \<100
  • CXR showing TB or evidence of other active infection
  • Prior receipt of a recombinant MVA or Fowlpox vaccine
  • Use of any investigational or non-registered drug, live vaccine or medical device other than the study vaccine within 30 days preceding dosing of study vaccine, or planned use during the study period
  • Administration of chronic (defined as more than 14 days) immunosuppressive drugs or other immune modifying drugs within six months of vaccination. (For corticosteroids, this will mean prednisolone, or equivalent, ≥ 0.5 mg/kg/day. Inhaled and topical steroids are allowed.)
  • History of allergic disease or reactions likely to be exacerbated by any component of the vaccine, e.g. egg products
  • Presence of any underlying disease that compromises the diagnosis and evaluation of response to the vaccine (including evidence of cardiovascular disease, history of cancer (except basal cell carcinoma of the skin and cervical carcinoma in situ), history of insulin requiring diabetes mellitus, any ongoing chronic illness requiring ongoing specialist supervision (e.g., gastrointestinal), and chronic or active neurological disease)
  • History of \> 2 hospitalisations for invasive bacterial infections (pneumonia, meningitis)
  • Suspected or known current drug and/or alcohol abuse
  • Seropositive for hepatitis B surface antigen (HBsAg) and/ or hepatitis C (antibodies to HCV)
  • +8 more criteria
