Hepatitis B virus (HBV) infection is one of the common reasons why some Taiwanese have chronic liver diseases, cirrhosis and hepatocellular carcinoma. Those chronic diseases threatened health level of Taiwanese young people, decreasing the human capital. Generally speaking, if the young are chronically infected with the HBV, hepatitis B will seriously interfere with economic activities in middle age. A nationwide program of hepatitis B vaccination has implemented in July 1984. In first two years, Newborns of HBsAg-positive mothers alone were vaccinated against HBV. After two years, all newborns have vaccinated in 1986. Numermous studies related with two programs revealed that prevalence of HBsAg was declining from 1984 until now. Because many epidemiology researches incidated the most severe phase of hepatitis B is the person whose age more than 30 years old, which makes me understand who are the samples of my article. The data resource came from Ministry of Health and Welfare, population and housing census 2010. I separated two genders in my data bases using Regression-Discontinuity Design to estimate causal relationships. Thus we exploited a dummy variable which represent program of hepatitis B vaccination and regarded monthly salary as independent variable. Whatever gender we estimated, our results suggest that both 1984 and 1986 programs are positive effect on monthly salary; also, program 1986 is more significant than 1984. Further, when Male had received hepatitis B vaccination in 1986, monthly salary would increase 1.07 percent. Otherwise, female who received hepatitis B vaccination in 1986 would raise to 0.79 persent. We hoped the variation of salary was only exogenously affected by hepatitis B vaccination, because we didn’t want the causal relationship to have endogeneity problems. Finally, we examined wheather the monthly salary was affected by education.
