Understanding the oscillations of an epidemic due to vaccine hesitancy - Published Aug 9, 2024
Vaccine hesitancy threatens to reverse the progress in tackling vaccine-preventable diseases. We used an SIS model with a game theory model for vaccination and parameters from the COVID-19 pandemic to study how vaccine hesitancy impacts epidemic dynamics. The system showed three asymptotic behaviors: total rejection of vaccinations, complete acceptance, and oscillations. With increasing fear of infection, stable endemic states become periodic oscillations. Our results suggest that managing fear of infection relative to vaccination is vital to successful mass vaccinations.
