In this paper, we developed a reaction-diffusion epidemic model with two aware classes and saturated treatment considering the impact of vaccination. We divided the total population into six classes, namely susceptible, vaccinated, completely aware, partially aware, infected, and recovered class. We discussed the basic properties of our system. With the help of Dirichlet boundary conditions and positive initial data, we studied the local and global existence in time of solutions. We performed a stability analysis of the equilibrium points, their existence, and found the basic reproduction number R of the system. Then, we established the occurrence conditions of Turing instability for our diffusive model. Finally, we have provided a thorough numerical exploration of our model to illustrate our analytical results by choosing a suitable set of parameters. 0enArticle
