The Oklahoma City-County Health Department is hosting two Pfizer clinics for the COVID-19 vaccine Tuesday.
The vaccine clinic at the county's Northeast Campus, near Northeast 63rd Street and North Martin Luther King Avenue, starts at 8 a.m.
The other starts at the same time at the Southern Oaks campus, near Interstate 240 and Walker Avenue.
Five hundred Pfizer doses will be available at each clinic.
Appointments are still available; people can sign up online at vaxokc.com. However, both sites will also be accepting walk-ins.
All Americans age 16 and older are now eligible to get the vaccine.
According to the CDC, more than half of all adults in the US have received at least one dose of the COVID-19 vaccine, with around 25 percent being fully vaccinated.
Oklahoma ranks about 26th in the country, with about 26 percent of people fully vaccinated.
The Johnson and Johnson vaccine remains on hold. The FDA just ordered a plant in Baltimore to stop production of the shot, after contamination was discovered.
