One to four children in a thousand die from measles, and half of the children who get tetanus will die from it. Furthermore, one or two children in a hundred fall ill with paralytic polio which cannot be cured (vaccines, ed. Noel). If the number of vaccinations continues to decline, the disease rate will continue to increase along with the death rate. Infant vaccination is important because their immune system is not as fully developed as that of an adult. The risk of children contracting a disease is even higher. Newborns are not able to fight off diseases well, and because they are so young and underdeveloped, there is a greater chance of death than adults. Vaccines are the safest substitute for a child's first exposure to a disease (vaccines and immunizations). The CDC promotes National Infant Immunization Week because newborns are at greatest risk for the disease. Without vaccines, the immune system can take a week or more to fight off a disease, but sometimes it can be too long (vaccines and vaccinations). In general, the benefits of vaccines outweigh the risks
