This paper is concerned with the existence and asymptotic behavior of traveling wave solutions for a nonlocal dispersal vaccination model with general incidence. We first apply the Schauder's fixed point theorem to prove the existence of traveling wave solutions when the wave speed is greater than a critical speed $c^*$. Then we investigate the boundary asymptotic behaviour of traveling wave solutions at $+\infty$ by using an appropriate Lyapunov function. Applying the method of two-sided Laplace transform, we further prove the non-existence of traveling wave solutions when the wave speed is smaller than $c^*$. From our work, one can see that the diffusion rate and nonlocal dispersal distance of the infected individuals can increase the critical speed $c^*$, while vaccination reduces the critical speed $c^*$. In addition, two specific examples are provided to verify the validity of our theoretical results, which cover and improve some known results.
