Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

An observational study to prospectively follow-up the patients enrolled in the ISS T-002 clinical trial up to 132 weeks. The primary endpoint of this study is to evaluate the persistence, in term of frequency, magnitude and quality, of the anti-Tat humoral and cellular immune response in the HIV-1 infected individuals who participated to the ISS T-002 and who have received at least 3 immunizations. The secondary endpoint is to define and validate novel laboratory tests for future efficacy clinical trials.
