C. Buddy Creech, MD, MPH, FPIDS is the Edie Carell Johnson Chair and Professor of Pediatrics, Division of Pediatric Infectious Diseases, at the Vanderbilt University School of Medicine in Nashville, Tennessee. He serves as Director of the Vanderbilt Vaccine Research Program, Principal Investigator of the NIH-funded Vanderbilt Vaccine and Treatment Evaluation Unit, and Co-Principal Investigator of the CDC-sponsored Clinical Immunization Safety Assessment Network. Dr. Creech’s research interests focus on the development and evaluation of new vaccines and therapeutics, particularly vaccines targeting influenza, pertussis, and S. aureus. His work combines innovative clinical trial design and next-generation immunologic assays to characterize the human response to infection and disease. He is currently leading COVID-related clinical trials at VUMC, including the evaluation of novel treatment options for hospitalized patients with COVID and clinical trials of SARS-CoV-2 vaccines.

Dr. Creech received a Bachelor of Science degree in Biology, cum laude, from Vanderbilt University prior to graduating with high honors from the University of Tennessee College of Medicine in Memphis, TN. He completed pediatric training at Vanderbilt Children’s Hospital, serving as Chief Resident in 2002. During fellowship in pediatric infectious diseases at Vanderbilt, he trained with Dr. Kathryn Edwards and received a master’s degree in public health. He is active in the Infectious Diseases Society of America (IDSA) and the Pediatric Infectious Diseases Society (PIDS), where he serves as President.

Dr. Stephanie Rolsma is an assistant professor in the Division of Pediatric Infectious Diseases at Monroe Carell Jr. Children’s Hospital at Vanderbilt.

Dr. Rolsma has experience in microbiology, vaccine development, and clinical research and her current research focuses on therapeutics and interventions in critically ill patients and clinical trials. Her primary research focuses on evaluating the utility of therapeutic drug monitoring of beta-lactam antibiotics in pediatric and adult patients, including cystic fibrosis patients and patients receiving intensive critical care. She also serves as a co-investigator in studies conducted through the NIH-funded Vanderbilt Vaccine and Treatment Evaluation Unit (VTEU), including Moderna and Janssen Phase 3 SARS-CoV-2 vaccine trials in adults, a Moderna Phase 2/3 SARS-CoV-2 vaccine trial in children, a Moderna Phase 1 SARS-CoV-2 variant vaccine trial in adults, a study of infant immune responses to RSV, and an intranasal influenza vaccine in pediatric patients. As a co-investigator for the CDC-funded Clinical Immunization Safety Assessment Network she works to address safety issues and clinical adverse events following vaccinations.

Dr. Rolsma received her B.S. in Microbiology from Michigan State University. She was awarded a Ph.D. in Microbiology and Molecular Genetics and M.D. from the Medical College of Wisconsin, where she was a part of the Medical Scientist Training Program. She completed a residency in pediatrics and a fellowship in pediatric infectious diseases at Monroe Carell Jr. Children’s Hospital at Vanderbilt.

_{A native of Costa Rica and with a background in Microbiology, Dr. Jimenez completed a master's degree in clinical investigation (MSCI) followed by a PhD in Epidemiology at Vanderbilt University. Her work has focused on observational studies of S. aureus and pertussis, laboratory studies of the clinical and molecular epidemiology of S. aureus colonization in children and young adults, and clinical trials of vaccines. She currently serves as a Quality Assurance Officer for the VVRP and serves in one of the Institutional Review Board (IRB) committees at VUMC.}

Natalya is a pediatric infectious disease fellow under the mentorship of Dr. Buddy Creech. Her fellowship research project focuses on immunometabolism profiling of critically ill children with congenital heart disease.

^{Dr. Howard's research focuses on vaccine-preventable diseases that have global impact. She has extensive experience in the developing world, serving as a physician in the Baylor International Pediatrics AIDS Initiative (BIPAI) prior to completing a pediatric infectious diseases fellowship at Vanderbilt. During fellowship, she completed a master's degree in public health, devoting a portion of her time to defining medication dosing errors in Mozambique. She now serves as a Fogarty Global Health Fellow at Vanderbilt and is working with colleagues at the Centre for Infectious Diseases Research in Lusaka, Zambia (CIDRZ). She continues to work on pathogens such as influenza and other respiratory pathogens, and continues to work in the developing world. Her current research focuses on the impact of respiratory pathogens on pneumococcal carriage in an Andean cohort (Peru).}

Dr. Sokolow is board-certified in Pediatric Pulmonary Medicine and have a strong clinical interest in pediatric chronic pulmonary disease, including cystic fibrosis, pulmonary manifestations of Duchenne muscular dystrophy and childhood asthma. His research includes collaborative efforts between the Divisions of Pediatric Infectious Disease and Pediatric Allergy, Immunology, and Pulmonary Medicine in clinical/translational work investigating immune response to methicillin-resistant Staphylococcus aureus (MRSA) in the pediatric cystic fibrosis and the respiratory interactions surrounding vaccines and vaccine preventable diseases. He presently serves as the associate pediatric Cystic Fibrosis Center director and co-director for the Duchenne Muscular dystrophy clinic.

Originally from Cleveland, Ohio, Kate attended Case Western Reserve University and completed her undergraduate degree in nursing in 2007.  After working for a decade as a bedside nurse in the Neonatal Intensive Care Unit, Kate completed her master’s degree at Vanderbilt University in 2015, where she specialized in Pediatric Primary Care.  Kate joined the Vanderbilt Vaccine Research Program in 2017, where she currently serves as a study nurse coordinator and pediatric nurse practitioner.  

Emily is a graduate from Auburn University where she got her degree in nursing in 2007. She spent the next decade at the bedside in critical care medicine. During this time she also served as the medical director for an organization in Haiti and spent time in New Zealand opening an ICU at a smaller hospital. She started working in research in 2015 in pharmacogenetics and oncology.  Emily joined the VVRP in 2021 to assist with the large scale COVID vaccine trails and currently serves as a study coordinator and registered nurse.

_{Wendy is a Belmont Graduate who began her work with the VVRP in 2020 to assist in large scale COVID vaccine trials during the height of the pandemic. She now manages the clinical schedule, most communications with participants and potential volunteers, the volunteer database, and spear heads recruitment efforts. She continues to support the clinical team in many ways to ensure studies run smoothly and participants volunteering in our studies have a positive experience.} 

Fiona joined the VVRP in the summer of 2021 after graduating from Lipscomb University with a degree in biology. She supports the clinical team by assisting with participant visits, helping with recruitment efforts, and performing phlebotomy along with other tasks. 

_{Ms. Soper is a licensed medical technician with extensive experience in microbiology and immunology. She is the laboratory manager for the VVRP Laboratory, overseeing projects focused on S. aureus, respiratory infections, and C. difficile infections.}

Eric is a University of Michigan graduate and joined the VVRP in 2017 by way of Duke University. He is heavily involved in VTEU (Vaccine and Treatment Evaluation Unit) and other clinical trials where he utilizes his experience in immunology, virology, and microbiology.
