In this paper, we investigate the fermion tunneling through the event horizon of a Vaidya black hole which is non-stationary. We further take into account the particle's self-gravitation in the dynamical background space-time, and calculate the tunneling probability. The result shows that the tunneling probability is related not only to the change of Bekenstein-Hawking entropy but also to the integral of the changing horizon, which is different from the case of stationary black holes.
