Vaccines Should Be Necessary In the late 18th century smallpox became a deadly epidemic, and Dr. Edward Jenner knew something needed to be done. He created the smallpox vaccine which led to vaccines becoming a public health practice. Thanks to medical advances today, vaccines have become a much safer and more reliable way to prevent many of the diseases that once killed thousands of people, and parents should be required to vaccinate their children to protect them and the children around them, a unless existing health conditions are an obstacle. .Vaccines have protected people for thousands of years from diseases that, when they became epidemics, killed or paralyzed thousands of people. Vaccines were created to act like the immune system, meaning that the vaccine contains components of the disease that have been altered to the point that they cannot harm the child and therefore allow the child's body to create a barrier against the disease. prevent them from getting it again and also without the possibility of the deadly consequences that come from contracting the disease ("Basic Information on How Vaccines Work"). Smallpox is an example of a plague that was very common among people in the early years and was a rapidly spreading disease that affected their immune system. The first battle against this disease is said to date back to 1000 AD, when the Chinese used elements of the smallpox virus to fight the disease which later led other countries such as Turkey and the Americas to do the same ("Timeline- History of Vaccines ”). This became the foundation on which other people built and improved vaccines that quickly took off and became a rapid trend throughout the world. In early America, smallpox and rabies were common killers among a large population. ..if polysaccharides in vaccines are not associated with autism risk." www.jpeds.com.
