From Rita Manly: After spending almost two hours trying to schedule our booster shots on line, I discovered the best place to get Covid booster shots is HAINES CITY HEALTH DEPT located at 1700 Baker Ave. Haines  City Fl.  They are open for shots on FRIDAYS, (excluding Holidays) from 11 AM until 6 PM and all you do is WALK IN!!   (closed Thanksgiving week on Fri.)
Note:  The street sign for Baker Ave. is located only on the left a ways past Johnson Ave. , but as soon as you see the sprawling green roof of the Health Dept. ,  you make a right turn and immediately turn left into the parking lot .  Hope that helps .  They are friendly and efficient there .  Rita Manly
