The development of communicable diseases changes rapidly and sometimes prevails to complicated situations in control. Therefore, it is an important vaccination strategy emphasizing transparency of information to help people understand the disease prevention messages and cooperate with health authorities. This study tried to collect historical data related to communicable diseases in Taiwan. We not only summarized the number of cases and deaths from contagious diseases with vaccinations of person-time frequencies but also used the graphic charts for the presentation. The bar chart displayed the number of cases and death using the years and persons as coordinate axes. The curve diagram displayed the vaccine inoculation number of places per thousand to observe the relationship between communicable diseases evolution and the implementation of vaccination policies. We conducted Excel PivotTable for all analyses. The trend had a dramatic decline after smallpox vaccine launched in 1946. In addition, we noticed a great improvement in polio case numbers as well as in Japanese encephalitis, diphtheria after the government introduced a unified vaccination record card in 1943 and urged mass immunizations among children. However, the results from tuberculosis vaccination were less obvious. This study uses elucidated charts, which can be done at a glance to examine the relationship between the vaccination policies and prevention of contagious diseases with the development of various statutory contagious diseases.
