Brazilian Ministry of Health Oswaldo Cruz Foundation Oswaldo Cruz Institute Mariza G. Morgado Lab. AIDS & Molecular Immunology HIV Vaccine Research: Ethical and Regulatory Issues PN-DST/AIDS – Brazilian Ministry of Health Brasília – Out 2006 Brazilian Experiences in Collaborative and Preventive Multicentric Studies – FIOCRUZ
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 WHO-Global Programme on AIDS Network for HIV Isolation and characterization
Brazilian Network of HIV Isolation and Characterization Objective: To establish a Brazilian surveillance program to monitor the genetic and antigenic variation of HIV and its possible implications for vaccine development 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 strategies (1993)

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.
