Brief Summary
The purpose of this study is to determine if HIV-specific canarypox vaccine and/or interleukin-2 (IL-2) will control viral load (amount of HIV in the blood) after HIV treatment is withdrawn for a certain time period.

Outcome Measures
Primary Outcomes (1)
Mean log10 viral load for each experimental group from the average of 5 values obtained during Weeks 21 to 25 (8 to 12 weeks following HAART interruption
Secondary Outcomes (3)
Proportion of participants who relapse during the first 12 weeks following stopping of HAART
length of time to the termination of Step II among participants
changes in frequency, activation state, and HIV-specific functional capacity of T and NK cells in blood, as monitored by expression of intracellular cytokines during the first 12 weeks after stopping HAART, with respect to termination of Step II
