From ancient times, humanity faced a variety of infectious diseases, accompanied by a high mortality rate despite the best efforts of doctors. These include smallpox, cholera, typhoid fever, plague, and others (The history of vaccination). The doctors began to think about how to prevent epidemics kill millions of people in the middle Ages. A wound discharge was used already in the XII century for the prevention of smallpox in China from cows that were ill with smallpox (cowpox non-communicable to humans). Edward Jenner planted to the human a cowpox, and coined the term "vaccination" in 1796 (from the Latin "vaca" - a cow), and since 1798 mass vaccination begins against smallpox in Europe. However, the scientific basis of immunization only developed 100 years later thanks to the work of Louis Pasteur. He introduced to the scientific world of his time queer theory: a vaccine made up of cultures of microbes that cause a particular disease, weakened air and heat. This culture has entered a healthy body, causing mild illness and creates immunity against serious infectious diseases (Riedel). Even though the effect of vaccination has brought and continues to be effective for people, many parents refuse to vaccinate in present time. This essay will focus on some reasons such as a link between vaccine and autism, hazardous substance, the ineffectiveness of some vaccines and effect of not having children vaccinated.
