Phase 1 clinical studies will soon evaluate novel HIV-1 envelope immunogens targeting distinct 'germline' and memory B cell receptors to ultimately elicit HIV-1 broadly neutralizing antibodies (bNAbs). The National Institute of Allergy and Infectious Diseases (NIAID) recently convened a panel of US-based expert scientists, clinicians, sponsors and ethicists to discuss the role of sampling draining lymph nodes within preventive HIV vaccine trials. The meeting addressed the importance of evaluating germinal center (GC) responses following immunization to predict bNAb potency and breadth, and reviewed key aspects of this procedure within the clinical research setting, including informed consent, adverse event monitoring, study participant acceptability, medical expertise and training. We review highlights from the meeting and discuss the advantages and disadvantages of sampling lymph nodes by excisional biopsies compared to fine needle aspirations (FNA) in the context of prophylactic HIV vaccine trials.
