First lady Jill Biden is asking Arizonans to get vaccinated. She stopped in Phoenix on Wednesday to highlight the need for higher COVID-19 immunization rates in the state.

Biden and second gentleman Doug Emhoff visited a vaccination event at a west Phoenix middle school. After greeting teenagers who were there to receive the Pfizer vaccine, Biden and Emhoff spoke to an audience that included several Arizona lawmakers and tribal leaders. Biden pointed out Arizona’s vaccination rate is behind the national average.

“Right now only about 40% of Arizonans are fully vaccinated and that’s just not enough,” Biden said. 

The White House had set a goal that 70% of U.S. adults would have at least one dose of a vaccine in time for the Fourth of July, but Arizona is likely to miss that target. The First Lady encouraged Arizonans to trust the safety of the vaccines. She pointed out the shots are free and doses are readily available now at many pharmacies and clinics.

“Do it for your health, do it for your children, do it for your grandparents and your neighbors. And we’ll be able to celebrate this holiday the way it should be, safe and together,” Biden said.

Emhoff pointed out vaccination rates are lowest among younger people. He said he had encouraged his two children, who are in their 20s, to get the shot.

“As a parent, I can sleep better at night when they’re out in the world knowing that they’re going to be safe," Emhoff said.
