| Research Abstract |
In this research, we have established the stochastic vaccination model which describes the spread of infection taking account of random fluctuations in the infection or the death rates caused by the environmental change and have clarified the influence of the random noise on the spread of infection. Moreover, we have constructed the stochastic optimal vaccination system which minimizes the side-effect and the cost of vaccination and the infected population. The efficiency of the proposed optimal vaccination strategy is verified by the numerical simulations.
