Tynan DeBold and Dov Friendman, from The Wall Street Journal, published interactive heat maps that illustrate case frequency of seven major vaccine preventable diseases in the United States using Project Tycho data. Case counts are available for all 50 states. By marking when a vaccine was introduced, the visualizations depict that following the introduction of vaccines has led to a reduction of cases of measles, hepatitis A, mumps, pertussis (whooping cough), polio, and rubella, as well as the eradication of smallpox.
