You may be eligible if
1. Male and female subjects aged between 18-45 years, vaccinia-naïve.
2. HIV-1 infection documented by ELISA and confirmed by Western blot at any time prior to study entry. HIV-1 deoxyribonucleic acid (DNA) polymerase chain reaction (PCR), HIV-1 culture, HIV-1 antigen, plasma HIV-1 ribonucleic acid (RNA), or a second antibody test other than ELISA is acceptable as an alternative test at any time prior to study entry.
3. On stable antiretroviral therapy (ART) i.e. Combination ART for at least 6 months. Subject must be on the same ART regimen for at least 12 weeks with no change prior to enrollment in this clinical trial.
4. Screening HIV-1 RNA \< 200 copies/ml by US Food and Drug Administration (FDA) approved PCR assay within 45 days prior to study entry.
5. Current CD4 counts ≥ 100 cells/µl ≤ 500 cells/µl.
6. Documented nadir CD4 count \< 200 cells/µl at any time prior to enrollment.
7. Hemoglobin ≥ 9.0 g/dl for female subjects, ≥ 10.0 g/dl or male subjects.
8. Platelets ≥ 100,000/mm3.
9. Ability and willingness of subject to provide written informed consent.
10. Body Mass Index (BMI) ≥ 18.5 and \< 35 kg/m2.
11. Women of childbearing potential (WOCBP) must have used an acceptable method of contraception for 30 days prior to the first vaccination, must agree to use an acceptable method of contraception during the trial, and must avoid becoming pregnant for at least 28 days after the last vaccination. A woman is considered of childbearing potential unless post-menopausal (defined as ≥ 12 months without a menstrual period) or surgically sterilized. Acceptable contraception methods are restricted to abstinence, barrier contraceptives, intrauterine contraceptive devices or licensed hormonal products).
12. WOCBP must have a negative serum pregnancy test at screening (SCR) and a negative urine pregnancy test within 24 hours prior to each vaccination.
13. Absolute neutrophil count cells ≥ 750/mm3.
14. Adequate renal function defined as a calculated Creatinine Clearance (CrCl) \> 60 ml/min as estimated by the Cockcroft-Gault equation.
1. For men: (140 - age in years) x (body weight in kg) ÷ (serum creatinine in mg/dl x 72) = CrCl (ml/min)
2. For women: multiply the result by 0.85 = CrCl (ml/min).Adequate hepatic function defined as: Total bilirubin ≤ 2 x upper limit normal (ULN) in the absence of other evidence of significant liver disease
15. Aspartate aminotransferase (AST), alanine aminotransferase (ALT) and alkaline phosphatase ≤ 2.5 x ULN.
16. Troponin I \< 2 x ULN at entry in the clinical trial.
17. Electrocardiogram (ECG) without clinically significant findings (e.g. any kind of atrioventricular or intraventricular conditions or blocks such as complete left or right bundle branch block, AV node block, QTc or PR prolongation, premature atrial contractions or other atrial arrhythmia, sustained ventricular arrhythmia, two premature ventricular contractions (PVC) in a row, ST elevation consistent with ischemia).
9. History of malignancy other than squamous cell or basal cell skin cancer, unless there has been surgical excision that is considered to have achieved cure. Subjects with history of skin cancer must not be vaccinated at the previous tumor site.
10. History or clinical manifestation of clinically significant and severe hematological, pulmonary, central nervous, cardiovascular or gastrointestinal disorders (except HIV infection, chronic or active Hepatitis-B-Virus or Hepatitis-C-Virus infection).
11. Clinically significant psychiatric disorder not adequately controlled by medical treatment.
12. History of coronary heart disease, myocardial infarction, angina pectoris, congestive heart failure, cardiomyopathy, stroke or transient ischemic attack, uncontrolled high blood pressure, or any other heart condition under the care of a doctor.
13. Known history of an immediate family member (father, mother, brother, or sister) who has had onset of ischemic heart disease before age 50 years.
14. Ten percent or greater risk of developing a myocardial infarction or coronary death within the next 10 years using the National Cholesterol Education Program's risk assessment tool (http://hin.nhlbi.nih.gov/atpiii/calculator.asp?usertype=prof). NOTE: This criterion applies only to subjects 20 years of age and older.
15. Current alcohol abuse (40 g/day for at least 6 month) and/or intravenous and/or intranasal drug abuse (within the past 6 months).
16. Known allergy to MVA-BN® vaccine or any of its constituents, e.g. tris (hydroxymethyl)-amino methane, including known allergy to egg or aminoglycosides.
17. History of anaphylaxis or severe allergic reaction to any vaccine.
18. Acute disease (illness with or without a fever) at the time of enrollment.
19. Body temperature ≥ 100.4°F (≥ 38.0°C) at the time of enrollment.
20. Having received any vaccinations or planned vaccinations with a live vaccine within 30 days prior to or after trial vaccination.
21. Having received any vaccinations or planned vaccinations with a killed vaccine within 14 days prior to or after trial vaccination.
22. Use of immunosuppressant or immunomodulatory agents including systemic glucocorticoids (excluding nasal or inhaled steroids), tacrolimus, sirolimus, rapamycin, mycophenolate, cyclosporine, TNF-alpha blockers or antagonists, azathioprine, interferon, growth factors, or intravenous immunoglobulin in the 60 days prior to enrollment in this clinical trial.
23. Post organ transplant subjects whether or not receiving chronic immunosuppressive therapy.
24. Administration or planned administration of immunoglobulins and/or any blood products during a period starting from three months prior to administration of the vaccine and ending at last physical trial visit.
25. Use of any investigational or non-registered drug or vaccine other than the trial vaccine within 30 days preceding the first dose of the trial vaccine, or planned administration of such a drug during the trial period.
26. Trial personnel.
You may not be if
1. Pregnant or breast-feeding women.
2. Typical vaccinia scar.
3. Known or suspected history of smallpox vaccination.
4. History of vaccination with any poxvirus-based vaccine.
5. Uncontrolled serious infection, i.e. not responding to antimicrobial therapy.
