Michael Strauss presented at the Institute for Disease Modelling Conference in Seattle, Washington, which was held from 22 to 24 May 2023. His presentation was about using Preference Modelling to understand COVID-19 Vaccine Hesitancy. The research that he presented showed that vaccine effectiveness was the strongest driver of preferences, with the number of doses, and the frequency of boosters being significant drivers of choice regarding vaccination. Waiting time and the possibility of a financial incentive for vaccination were also significant in participants’ preference structures.
