Brief Summary

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

The aim of this study is the assessment B-cell immune responses in HIV-infected individuals.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Groups of patients with different immune competencies will be examined. The impact of HIV infection on immune response will be assessed.
