| Abstract: | Based on the infection characteristics of Hepatitis B,assuming that infection rate depends on individuals's chronological-age and infection age and that the vaccination has definite,a mathematical model with chronological-age and infection-age was developed.The existence of endemic steady state are studied. |

| Keywords: | vaccination Infection-age chronological-age endemic steady state |
