摘要：
A delayed SIRS epidemic model with pulse vaccination is proposed. Using Krasnoselskii's fixed-point theorem and the comparison method, the existence and global attractivity of the disease-free periodic solution are obtained. Further, we obtain the conditions that guarantee the permanence of the disease. These results indicate that a large pulse vaccination rate will lead to the eradication of the disease.
