Vaccination campaigns have led to the successful decline of many diseases. Thanks to immunization, children today don’t have to get the smallpox vaccine since the disease has been eradicated. Continued efforts can increase the likelihood of other diseases no longer existing one day as well.

The Global Immunization Vision and Strategy (GIVS) developed by the WHO and UNICEF was started in 2006. They established a 10-year plan designed to control morbidity and mortality from vaccine-preventable diseases. In addition to other strategies, some of the main goals of GIVS include reducing “by at least two thirds compared with 2000 levels” global childhood morbidity and mortality, ensuring access to vaccines, and introducing new vaccines.

As the CDC advises, “We don't vaccinate just to protect our children. We also vaccinate to protect our grandchildren and their grandchildren… Vaccinations are one of the best ways to put an end to the serious effects of certain diseases.”
