New paper (Wallrafen-Sam): Responsive Vaccination Decisions and SARS-CoV-2 Spread
New paper led by Karina Wallrafen-Sam in Epidemics: Modelling the Interplay Between Responsive Individual Vaccination Decisions and the Spread of SARS-CoV-2. The study coupled a network- and agent-based model of SARS-CoV-2 transmission with a social-psychological decision-making model in which side effects and breakthrough infections nudged individuals toward vaccine resistance while spikes in COVID-19 hospitalizations nudged them toward willingness, calibrated to the epidemic in Georgia, USA from January 2021 to August 2022. In the model, raising the probability of hospitalization-prompted resistant-to-willing nudges increased vaccine uptake by as much as 5.4% and decreased SARS-CoV-2 incidence by as much as 4.0% relative to the calibrated baseline, whereas decreasing breakthrough-related willing-to-resistant nudges had negligible impact.
