Ethics of Challenge Studies

Challenge studies are a form of research where healthy volunteers are deliberately challenged with an infection in order to enable research to take place. It is now being used to enable COVID-19 vaccine research to better establish the efficacy of  vaccine candidates, although it is controversial given the risk of harm to volunteers. In this series of papers, we explore the ethics of challenge studies.
