According to the Rock County Health Department, 41 percent of kindergartners are not up-to-date on vaccines.
The Health department hosted immunization clinics in Beloit and Janesville on Wednesday.
Eleven-year-old Nick Zimmerman got all of the shots required for a sixth grader. At a clinic in Beloit he was vaccinated against meningitis.
"Protection against any other kids that might come around him with these diseases," said Nick's mom, Robin.
Janet Zoellner, Rock County's public health nursing director, said the county is in the midst of a whooping cough outbreak.
"We're still up over 2,000 kids in Rock County in kindergarten and sixth grade that still don't have their whooping cough vaccine,” Zoellner said.
She said paying for your child's vaccines should be easier this year.
"If you are on any HMO in Wisconsin or any health plan that hasn't been grandfathered in, then starting Aug. 1 your insurance plan should cover your immunizations," said Zoellner.
She recommends families go sooner rather than later to save school districts from spending a lot of time contacting families to verify vaccinations.
