Gov. Doug Ducey announced March 22 that registration at Arizona's state-run COVID-19 vaccination sites in Maricopa, Pima and Yuma counties will open to all Arizonans 16 and older beginning at 8 a.m. March 24.

“Our goal has been and remains to get vaccine into the community as quickly, widely and equitably as possible,” Ducey said in a news release. “Given a thorough review of vaccination data, anticipated vaccine supply, and current demand among prioritized groups, now is the time to take this critical next step.”

As of March 22, Arizona has administered 2,904,159 doses of COVID-19 vaccine to 1,831,456 individuals, including 1,136,413 who are fully vaccinated, according to the Arizona Department of Health Services. As of March 22, there were over 58,000 appointments still available from Friday’s release.

“We anticipate more and more vaccine reaching Arizona heading into April, making it possible now to expand prioritization,” said Dr. Cara Christ, director of the ADHS, in a news release. “We have been flexible and nimble throughout, while expanding the availability of state sites to vaccinate large numbers of people rapidly.”

ADHS now opens appointments at 11 a.m. each Friday for State Farm Stadium in Glendale, Arizona State University’s Phoenix Municipal Stadium in Tempe, Chandler-Gilbert Community College, the University of Arizona in central Tucson, and, as of March 26, Yuma Civic Center in Yuma County, according to the release.

Sites using the Pfizer vaccine, including those run by the state, can vaccinate those 16 and older. The Moderna and Johnson & Johnson/Janssen vaccines, which are allocated to counties, are approved for those 18 and older, according to the release.
