In this episode of "Research Ethics Reimagined," we explore human challenge studies for shigellosis, examining their role in vaccine development and the ethical considerations surrounding intentional infection of healthy volunteers. Our guests are Dr. Wilbur H. Chen, the Frank M. Calia, MD Endowed Professor and Chief of the Division of Geographic Medicine at the University of Maryland School of Medicine, and Jake Eberts of 1Day Sooner, who is a former participant in a Shigella challenge trial.
