Jessica Fleming is a Product Development Director and the Maternal Immunization Delivery Lead in the Policy, Access and Introduction program within PATH’s Center for Vaccine Introduction and Access. With over twenty five years of experience working in international public health, she provides public health leadership in evaluating the impact of vaccines and health technologies appropriate for low resource settings and generating evidence to assist countries in preparing for new vaccine introduction. Dr. Fleming currently leads the Advancing Maternal Immunization (AMI) collaboration that enables efficient, well-informed decisions around the introduction of maternal immunizations in low- and middle-income countries, with a special emphasis on maternal vaccines for respiratory syncytial virus. She leads formative research on maternal vaccine decision-making and acceptance. Her work includes conducting clinical studies to quantify the impact of vaccines and improve their performance in low-income populations and contributing to global guidance on the use of safe injection technologies and waste management. Before joining PATH in 2003, Dr. Fleming lived and worked in a number of complex emergency and humanitarian relief settings in Africa and Asia. Dr. Fleming holds a Doctorate of Philosophy in epidemiology from the University of Washington and a Master of Science in tropical public health from the Harvard School of Public Health with a concentration in infectious disease epidemiology and international health. She is an affiliate assistant professor in the Epidemiology Department at the University of Washington.
