CLEVELAND — The mass vaccination site at Cleveland State University's Wolstein Center is a major milestone for Ohio in the fight against COVID-19. 

The center has administered more than 237,000 first and second doses of the Pfizer vaccine alone, according to Gov. Mike DeWine, and many of the people working behind the scenes to keep it running are members of the Ohio military. 

Alison Ruble, the regional president with the United Service Organizations (USO) Midwest Region, said they're making sure service members are being supplied with the items they need to keep helping the state. 

"They're working long shifts, seven days a week, really protecting and helping us with a COVID-19 relief on a community level," Ruble said. 

Among USO's efforts is supplying members with comfort items, such as food and other necessities they may need. Ruble said there's "literally thousands" of service members deployed in Ohio to help the vaccination rollout, including National Guard members and those in active duty.
