Qian Wang is a master’s student in public health and will commence her PhD at the School of Public Health, Fudan University in late 2026. Her research focuses on developing and evaluating interventions to address vaccine hesitancy using randomised controlled trials (RCTs). She has led two projects in this area. Her master’s thesis evaluated the effectiveness of digital messaging nudges in reducing influenza vaccine hesitancy among parents of children aged 6 to 35 months, with findings published as an independent first-author paper: A Cluster Randomized Trial of Digital Messaging Nudges to Improve Influenza Vaccination Uptake in China (NPJ Digital Medicine, 2025).

She is currently responsible for leading this project. These studies draw on behavioural science to improve
