Iowa officials are concerned over the increase in parents choosing not to vaccinate their children.
The parents received vaccination exemptions in the 2012-13 school year for nearly 8,000 children. That’s more than triple the number from 12 years ago.
While the figure represents less than 2 percent of all Iowa children, health leaders say they’re worried about the rise in unvaccinated children.
Polk County’s public health director Rick Kozin says some parents might not realize that unvaccinated children could lead to a disease outbreak in schools.
Iowa laws allow two kinds of exemptions for medical or religions reasons. Some children have to avoid vaccinations for medical reasons such as allergies.
