No appointments are required at the drive-through site, but anyone seeking a shot must meet state guidelines. As of Tuesday afternoon, state and federal officials had not revealed a location for the next satellite site in Polk County. Wednesday is the final chance to get a COVID-19 vaccination without an appointment at a federally supported site in northwest Lakeland. FEMA is operating a satellite site at Walker Road Park, 1035 Walker Road, from 9 a.m. to 5 p.m. The site, which opened Thursday, was scheduled to receive 500 doses a day and dispense them on a first-come, first-served basis. No appointments are required at the drive-through site, but anyone seeking a shot must meet state guidelines, FEMA spokeswoman Hallie Anderson said. The vaccines are available to those age 60 and older, anyone with a doctor’s note saying they are extremely vulnerable to COVID-19, firefighters and law-enforcement officers 50 and older, adult teachers and health care workers who have direct contact with patients.
