(Green Lake County) The Green Lake County Health Department has announced a change for its Walk-In Wednesday COVID vaccine clinics. The county health department’s vaccination site is now being supported by the National Guard WING team. They will still have walk-in hours from 10am to 2pm every Wednesday. However, individuals wishing to be vaccinated will now be required to pre-register, which can be done in advance online. You do not need to pick a specific location or create an appointment, just go through the registration process. Both Pfizer and Johnson and Johnson vaccines will be offered at the clinic.
