Neonatal Rhesus Macaques Have Distinct Immune Cell Transcriptional Profiles following HIV Envelope Immunization.

Dr. Williams completed a PhD in Biomedical Sciences (Immunology and Microbiology) from the University of Florida and did his postdoctoral work in the laboratory of Dr. Barton Haynes at the Duke Human Vaccine Institute (DHVI).

The key goals of HIV vaccine development are to define the host-virus events during natural HIV infection that lead to the induction of broadly neutralizing antibodies, and to recreate those events with a vaccine. As a junior faculty member in the DHVI, Dr. Williams is further characterizing SHIV non-human primate models for HIV infection, and evaluates B cell responses to HIV-1 vaccination in humans and non-human primates.

My research focuses on the interactions of T cells and B cells during infection or following vaccination. I am particularly interested in the inter- and intracellular events that take place within germinal centers, the anatomic site of antibody evolution during an immune response.

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.  

Barton F. Haynes, M.D. is the Frederic M. Hanes Professor of Medicine and Immunology, and Director of the Duke Human Vaccine Institute. Prior to leading the DHVI, Dr. Haynes served as Chief of the Division of Rheumatology, Allergy and Clinical Immunology, and later as Chair of the Department of Medicine. As Director of the Duke Human Vaccine Institute, Bart Haynes is leading a team of investigators working on vaccines for emerging infections, including tuberculosis, pandemic influenza, emerging coronaviruses, and HIV/AIDS.

To work on the AIDS vaccine problem, his group has been awarded two large consortium grants from the National Institutes of Health (NIH), National Institute of Allergy and Infectious Diseases (NIAID) known as the Center for HIV/AIDS Vaccine Immunology (CHAVI) (2005-2012), and the Center for HIV/AIDS Vaccine Immunology-Immunogen Discovery (CHAVI-ID) (2012-2019) to conduct discovery science to speed HIV vaccine development. In July 2019, his team received the third of NIH “CHAVI” awards to complete the HIV vaccine development work - CHAV-D.

Since the beginning of the COVID-19 pandemic, Haynes and the DHVI Team has been working non-stop to develop vaccines, rapid and inexpensive tests and therapeutics to combat the pandemic. Since March 2020, he has served as a member of the NIH Accelerating COVID-19 Therapeutic Interventions and Vaccines (ACTIV) committee to advise on COVID-19 vaccine development, and served as the co-chair of the ACTIV subcommittee on vaccine safety. Haynes is the winner of the Alexander Fleming Award from the Infectious Disease Society of America and the Ralph Steinman Award for Human Immunology Research from the American Association of Immunologists. He is a member of the National Academy of Medicine, National Academy of Inventors and the American Academy of Arts and Sciences.
