Mississippi has the nation’s highest kindergarten vaccination rate. Idaho’s rate is among the nation’s lowest.
What separates these two states — so often neighbors in national demographic rankings?
The answer can be found in the states’ laws. Mississippi essentially requires all parents to immunize their children before kindergarten. In Idaho, parents can use three different types of waivers to get out of immunizing their children. And Idaho schools have no recourse but to accept the paperwork and enroll these students.
