CLEVELAND — Monday is the last day to get the COVID-19 vaccine at Cleveland State University's Wolstein Center mass vaccination site.

The site opened in mid-March, and the state initially planned to have it open for only eight weeks. The Ohio Department of Health and the Federal Emergency Management Agency (FEMA) decided to keep it open for an additional four weeks. 

"This clinic has been tremendously successful, and the process to get in and out the door here has been fast and efficient for both youth and adults," Gov. Mike DeWine said in May when he announced the center was closing. 

More than 260,000 vaccine doses have been administered at the center, according to the Ohio National Guard. 

Walk-ins are welcome from 8 a.m. to 7 p.m. Monday, and those wanting a vaccine will get Pfizer, which the site has been distributing for the last week. 

Those who received the first dose of the vaccine at the Wolstein Center and still need their second shot after it closes will need to schedule an appointment at a nearby Discount Drug Mart.

The center is the second mass vaccination site to announce its closing. The Schottenstein Center at Ohio State shut down operations in May and moved its clinic to Ohio State East Hospital.

As of Sunday, more than 46% of the state's population has received the first dose of the COVID-19 vaccine, and 40% of the population is completely vaccinated, according to state data.
