As a part of KJZZ's Q&AZ project, one listener asked: Does the listed number of Arizonans vaccinated only reflect Arizona residents?

The Arizona Department of Health Services’ data dashboard shows a running total of COVID-19 vaccinations in the state. This information is divided by day, age, gender, race, county, and even ZIP code. 

However, because state residency is not required to receive a vaccine, the dashboard does not collect residency information. Anyone receiving a vaccine in Arizona — including snowbirds and other visitors from out of state, is incorporated into the statistics.

Some Arizona counties, like Gila County, have exclusively vaccinated their own residents. But, both of Arizona’s largest counties, Maricopa and Pima, do not require residency to receive a vaccine.

This means that the percentage of Arizonans vaccinated is likely inaccurate, because part of that calculation is the state’s population.

Those qualified for vaccination are allowed to receive one dose in one state and one in another, as long as both vaccines are produced by the same company.
