Mission To inspire hope and promote health through integrated clinical practice, education, and research.

Background: The Mayo Clinic is a nonprofit academic medical center focused on clinical practice, education, and research. The clinic evolved from the private medical practice of William Worrall Mayo and his two sons, William James and Charles Horace, in Rochester, Minnesota, where the flagship clinic is located. The Mayo Clinic now has medical centers in Jacksonville, Florida, and Scottsdale, Arizona; a regional healthcare system; a medical school; and a global network of like-minded hospitals that put into practice W.W. Mayo's belief that "the needs of the patient must always come first." Today Mayo Clinic employs approximately forty-five hundred physicians and scientists involved in thousands of studies and clinical trials.

Mayo Clinic data scientists have added a vaccine tracker to Mayo's COVID-19 Resource Center that includes state-by-state data and trends to enable users to follow the COVID-19 vaccine rollout in all fifty states and compare progress on one- and two-shot vaccinations. The resource also provides guidance on what the trends mean for travel and keeping one's family safe.

Outstanding Web Features: The Mayo Clinic's state-by-state vaccination tracker compiles data from three sources: the Centers for Disease Control and Prevention, historical data pulled from the COVID Tracking Project, and population data from the 2019 census estimates obtained from the United States Census Bureau. Visitors using the online tool can scroll over an interactive color-coded map showing the percentage of each state's population who has received at least one dose of the COVID-19 vaccine and the percentage of those who are fully vaccinated. The stats are also provided as a table. In addition, visitors can find out how quickly the U.S. population is getting vaccinated in a graph that shows how the percentage of the population with at least one dose and that of fully vaccinated people has changed over the previous sixty days. Users also can see a breakdown by age.

The site also attempts to answer questions about the vaccines, including: Why should someone get a COVID-19 vaccine as soon as it's available? Are fast-tracked COVID-19 vaccines safe? What are the possible side effects? Can the vaccines cause other serious problems? Will children need the vaccine if they don't frequently experience severe illness? In addition, visitors can check current COVID-19 hot spots as well as trends up to two weeks into the future with the Mayo Clinic's prediction model.
