A New Fractional Modelling on Susceptible-Infected-Recovered Equations with Constant Vaccination Rate

Nonlinear Engineering, 2014
In this article, the authors introduce a fractional order SIR model with constant vaccination rate. The SIR model has been used in the modeling of several epidemiological diseases, biology and medical sciences. Qualitative results show that the model has
