Starting Friday, Pima County is expanding their vaccine eligibility to essential front line workers and those 55 and older. 

Dr. Theresa Cullen, the county’s health director, says front line workers include workers in food, agriculture, grocery stores, restaurants, public transit and postal service.

“[A] front line essential worker is someone who needs to work with the public and they routinely are less than 6 feet for more than 15 minutes in those situations," Cullen said.

Cullen is pleased to see the decreasing number of cases but she says the battle is far from over. There are at least four cases of the U.K. variant in the county.

Pima has several vaccination sites, including one on the University of Arizona campus, Kino Stadium, the Tucson Medical Center and the Tucson Convention Center.
