WHO-Global Programme on AIDS Network for HIV Isolation and characterization • Objective: To obtain information on genetic and antigenic variation of HIV and its possible implications for vaccine development • Primary laboratories – Brazil, Rwanda, Thailand and Uganda • Secondary International laboratories for: • Standardized virus isolation – repository • Genetic subtyping – PCR gag fingerprint, HMA, V3 loop and env DNA sequencing • Biological and immunological characterization - peptide binding EIA, CD4/gp120 blocking antibodies, in vitro replication characteristics and cross-neutralization assays
Brazilian Network of HIV Isolation and Characterization (1993) Objective: To establish a Brazilian surveillance program to monitor the genetic and antigenic variation of HIV and its possible implications for vaccine development Major strategies • Identification of potential participants; • Organization of local seminars for protocol definition and implementation; • Submission to WHO and PN-DST/AIDS funding; • Organization of local “International Workshop Trainings”; • In-country and international personnel trainings; • Elaboration and conduction of scientific projects

Major ethical and regulatory issues • Timeline to get the protocols approved. • Concerns about the storage of biological samples for further studies. • Timeline to prepare the documents (IL) and have them accepted for drug and reagent reception • Timeline to prepare the documents and have them accepted for importation and/or customs clearance of biological panels for laboratory proficiency tests. • Constant modifications in documentation required for shipping and/or clearance of drugs, reagents, and biological materials, including proficiency panels.
