According to the epidemic state, propagation mode and transformation be- tween HBV infection states, the Hepatitis B Virus (HBV) infection with impulsive vac- cination and time delay are modelled and analyzed. The control methods of impulsive vaccination and active therapy are adopted. By using comparative theorem of impulsive differential equation, the sufficient conditions that Hepatitis B Virus will be eliminated eventually or be persistent are derived.
