In September 2020, I started working on a multidisciplinary PhD project "understanding vaccine hesitancy" where I am looking at why people decide to refuse or delay vaccines. I am supervised by Florian van Leeuwen (Social psychology department), Peter Achterberg (Sociology department), and Mariëlle Cloin & Ien van de Goor (both Tranzo department). By combining insights from multiple social sciences we hope to get a better understanding why people decide to refuse or delay vaccines.
