%X In this paper, an SEIR epidemic disease model with integral delay and vertical transmission is considered, and dynamics behaviors of the model under pulsevaccination are analyzed. The sufficient condition for infection-extinction is obtained. Then, by using the theory on delay functional and impulsive differential equation theory, the sufficient condition of the permanence for the system with time delay is given. Finally, it is shown that time delays and pulse vaccination can bring obvious effects on the dynamics behaviors of the model.
