A series of pulses vaccination in SIR model โ€“ Understanding periodic orbits and irregular trajectories

Abstract When a Susceptible-Infective-Recovered (SIR) model with a constant contact rate is used to describe the dynamics of directly transmitted infections, oscillations, which decay exponentially with time, are obtained. Due to damped oscillations, intermittent vaccination schemes can be designed in order to reduce or even eliminate the infection. A simple โ€ฆ
