We propose an epidemic model consisting five compartments within a total
population with Crowley-Martin incidence rate and Holling type II treatment,
where total population is separated by the susceptible, the vaccinated, the exposed, the infected and the removed in this paper. We firstly prove that the
epidemic model admits a unique global positive solution by contradiction. We
then find out that diseases tend to extinction provided that the basic reproduction number is less than one. Moreover, the sufficient conditions of persistence
for infectious diseases are obtained by constructing suitable Lyapunov functions.
