Potential To Streamline Heterologous DNA Prime and NYVAC/Protein Boost HIV Vaccine Regimens in Rhesus Macaques by Employing Improved Antigens.

Dr. Montefiori is Professor and Director of the Laboratory for HIV and COVID-19 Vaccine Research & Development in the Department of Surgery, Division of Surgical Sciences at Duke University Medical Center. His major research interests are viral immunology and HIV and COVID-19 vaccine development, with a special emphasis on neutralizing antibodies.

Multiple aspects of HIV-1 neutralizing antibodies are studied in his laboratory, including mechanisms of neutralization and escape, epitope diversity among the different genetic subtypes and geographic distributions of the virus, neutralizing epitopes, requirements to elicit protective neutralizing antibodies by vaccination, optimal combinations of neutralizing antibodies for immunoprophylaxis, and novel vaccine designs for HIV-1. Dr. Montefiori also directs large vaccine immune monitoring programs funded by the NIH and the Bill & Melinda Gates Foundation that operate in compliance with Good Clinical Laboratory Practices and has served as a national and international resource for standardized assessments of neutralizing antibody responses in preclinical and clinical trials of candidate HIV vaccines since 1988.

At the onset of the COVID-19 pandemic he turned his attention to SARS-CoV-2, with a special interest in emerging variants and how they might impact transmission, vaccines and immunotherapeutics. His rapid response to emerging SARS-CoV-2 variants of concern provided some of the earliest evidence of the potential risk the variants pose to vaccines. In May 2020, his laboratory was recruited by the US Government to lead the national neutralizing antibody laboratory program for COVID-19 vaccines.

His laboratory utilizes FDA approved validated assay criteria to facilitate regulatory approvals of COVID-19 vaccines. He has published over 750 original research papers that have helped shape the scientific rationale for antibody-based vaccines.

Dr. Georgia Tomaras is a tenured Professor of Surgery, Professor of Immunology, Professor of Molecular Genetics and Microbiology and is a Fellow of the American Academy of Microbiology (AAM) and a Fellow of the American Association for the Advancement of Science (AAAS).  Dr. Tomaras is Co-Director of the Center for Human Systems Immunology (CHSI) Duke University and Director of the Duke Center for AIDS Research (CFAR). Her national and international leadership roles include: Executive Management Team (EMT) leader and mPI for the HIV Vaccine Trials Network (HVTN); Director of Lab Sciences (HVTN); and Chair of NIH Vaccine Research Center (VRC) Board of Scientific Counselors. Her prior leadership roles include serving as the Director of Research, Duke Human Vaccine Institute (DHVI); Director of the DHVI Training Program; Associate Director of DHVI Research; Co-Director of the Interdisciplinary Research Training Program in AIDS (IRTPA) Duke; Chair of the National Institutes of Health (NIH) AIDS Vaccine Research Subcommittee (AVRS), and Advisory Counsel member of the National Institutes of Health (NIH) National Institute of Allergy and Infectious Diseases (NIAID). Dr. Tomaras’ primary research focus is deciphering mechanisms of protective human immunity and identification of immune correlates of protection to further development of effective vaccines against infectious diseases.  

The activities of the Ferrari Laboratory are based on both independent basic research and immune monitoring studies. The research revolves around three main areas of interest: class I-mediated cytotoxic CD8+ T cell responses, antibody-dependent cellular cytotoxicity (ADCC), gene expression in NK and T cellular subsets upon infection with HIV-1. With continuous funding over the last 11 years from the NIH and Bill & Melinda Gates Foundation along with many other productive collaborations within and outside of Duke, the Ferrari Lab has expanded its focus of research to include the ontogeny of HIV-1 specific immune responses that work by eliminating HIV-1 infected cells and how these can be induced by AIDS vaccine candidates.
