Introduction : In the Middle Ages, it seemed that humankind would come to an end because of the spread of smallpox. However, because Edward Jenner discovered vaccination against smallpox, humankind survived, and smallpox disappeared on the earth. We were also vaccinated during our childhood, so we still have vaccination scars on our arms. We were vaccinated so we could become immune to smallpox and easily overcome it. In order to live successful lives, we should have immunity not only from disease-physical resistance, but we also need inner resistance in our hearts.
