The Fond du Lac County Health Officer hopes problems that caused long delays at a drive-thru booster clinic have been ironed out for a second clinic this week. Public Health Officer Kim Mueller says the Health Department is again partnering with the National Guard to provide Pfizer booster vaccines this Friday at the Fond du Lac County Fairgrounds Cow Palace. Mueller says while more than 250 people received a booster shot last Friday many people had to wait in line for more than two hours to get their shot. Mueller says that was unacceptable and says steps have been taken to make sure it doesn’t happen again. The clinic will be held this Friday from 10am to 6pm for eligible individuals who received their initial vaccine series at least six months ago, including peoples ages 65 and older, those ages 18-64 with certain medical conditions or who live in long term care settings and employees and residents at increased risk including first responders, education staff, grocery store, manufacturing, postal service and corrections workers.
