Sean E Richey, Ph.D
About
Dr. Sean E. Richey is a researcher specializing in vaccine immunology, with a body of work focused on antibody responses to viral pathogens including influenza, HIV, and SARS-CoV-2. His research examines how the immune system responds to vaccination and infection at a structural and molecular level, with particular attention to polyclonal antibody responses, broadly neutralizing antibody precursors, and adjuvanted vaccine platforms.
Across more than 75 peer-reviewed publications, Dr. Richey has contributed to studies exploring topics such as chimeric hemagglutinin-based influenza vaccines, HIV envelope glycoprotein immunofocusing strategies, and structural serology of mRNA-based COVID-19 vaccines. His work has appeared in journals including Nature Immunology, NPJ Vaccines, Cell Reports, and mBio, reflecting sustained engagement across virology, structural biology, and translational vaccine science. Several of his studies have involved nonhuman primate models, examining long-lived immune responses in bone marrow and lymph nodes following vaccination.
