Overview
Brief Summary
The purpose of this study is to determine the safety of an immune response to an investigational HIV vaccine, ADMVA, at three different dosage levels, in adults who are not infected with HIV
Detailed Description
This is a dose escalation trial. Study site staff and volunteers will be blinded. Blinding will not apply to the assignment of dose levels (low, middle or high). Volunteers will be screened up to 42 days before enrolment and will be followed for 18 months after the first vaccination. 16 volunteers will be randomized in a 3:1 ratio of active vaccine to placebo. Safety and tolerability of the ADMVA vaccine/placebo will be evaluated at least 14 days after the 12th volunteer in the low dose group receives the second injection before proceeding to the middle dose group.

Exclusion Criteria
- •Confirmed HIV-1 or HIV-2 infection;
- •Reported high-risk behavior for HIV infection defined as:
- •Within 6 months before vaccination, the volunteer has:
- •Had unprotected vaginal or anal sex with a known HIV infected person or with a casual partner.
- •Engaged in sex work for money or drugs
- •Used injection drugs (illicit), or
- •Acquired an STD;
- •Any clinically significant abnormality on history or examination including history of immunodeficiency or autoimmune disease; use of systemic corticosteroids, immunosuppressive, antiviral, anticancer, or other medications considered significant by the trial physician within the last 6 months;
- •Any clinically significant acute or chronic medical condition requiring care of a physician (e.g., diabetes, coronary artery disease, rheumatologic illness, malignancy, substance abuse) that in the opinion of the investigator would preclude participation;
- •Any of the following abnormal laboratory parameters listed below:
