The effect of pulse vaccination in an epidemic model
In this paper, a mixed pulse vaccination strategy in epidemic model with latent times is considered. The dynamic of this disease model under pulse vaccination are analyzed, we obtain the exact infection-free periodic solution of the impulsive epidemic system and prove that the infection-free periodic solution is global attractive. Therefore impulsive vaccination strategy provides a more natural, more effective vaccination strategy.
