This paper studies the extinction and persistence in the mean of a stochastic SIS epidemic model with vaccination.

The 4-nitrophenol is recognized for its hazardous nature, carcinogenetic, toxicity, and persistence in the environment, which is become a common pollutant in nature and waste water [23].
Sufficient conditions for stochastic asymptotically bounded, extinction, non-persistence in the mean, weak persistence, and persistence in the mean are established.
The metal contaminations in the aquatic environments have received considerable concern due to their toxicity, abundance and persistence in the environment, and their subsequent accumulation in aquatic habitats.
In the following part, we will discuss the sufficient conditions for several cases, such as extinction and weak persistence, nonpersistence and persistence in the mean and so on.
