Starting Thursday, May 13, children as young as 12 will be eligible to receive the Pfizer COVID-19 vaccines at select locations run by the state and county and local pharmacies in Pima County.

The announcement comes after the Food and Drug Administration and the Centers for Disease Control and Prevention authorized the Pfizer vaccine to be used for children ages 12-15. Previously it was authorized for anyone 16 and older. 

For now, the Moderna and Johnson & Johnson vaccines are still only authorized for people who are 18 and older. 

So far, Pfizer vaccines for children 12 and older will be available at the vaccination sites at the University of Arizona, Udall Park, and some mobile clinics and pharmacies.

Appointments are no longer required at the University of Arizona site in the Ina E. Gittings Building, 1737 E. University Blvd, near North Campbell Avenue. When you pull onto University Boulevard from Campbell Avenue, you'll be given instructions about where to park. You can simply show up any time between 10 a.m. and 5 p.m., seven days a week. 

Appointments are recommended, but not required for the vaccination site at the Morris K. Udall Center at Udall Park, 7200 E. Tanque Verde Road. The site is open 8 a.m. to 5 p.m., Monday through Friday. If you prefer to make an appointment instead of just showing up you can do so online at

The Pima County Health Department will host a mobile vaccine clinic with the Pfizer vaccine open to any 12 and older on Thursday, May 13 at Canyon del Oro High School, 25 W. Calle Concordia, just show up anytime between 4:30-7:30 p.m.

Anyone under 18 needs a parent or legal guardian to be present at their appointment to fill out consent forms, or an accompanying adult can bring a notarized letter stating that the parent allows that adult to complete the consent forms on their behalf. 

Vaccines are being administered at several sites run by the county, state, federally qualified health centers and pharmacies throughout Pima County. There are now several options for walk-in appointments with no advance registration necessary. 

Go to to find a list of all the major vaccination sites in Pima County. The site also includes a schedule of upcoming mobile vaccine clinics, and shows which sites accept walk-ins, which sites require an appointment in advance and the type of vaccine being offered at each location. The site can be viewed in Spanish here.

Information about all vaccination sites across the state including pharmacies, state-run sites, healthcare providers, and Federally Qualified Health Centers can be found at

Vaccines are free at all locations. You do not have to have health insurance to receive a free vaccine, you may be asked to provide your insurance information, if you are insured, but you will not have to pay anything out of pocket. 

Be sure to have a photo ID with you when you show up for your appointment. This does not have to be an ID issued by the state of Arizona, it just has to have your name, date of birth and a photo.
