Vaccine hesitancy is on the rise. Nationally, it’s an issue, and the non-medical exemption rate continues to increase annually. According to the Centers for Disease Control and Prevention, 4.6 percent of children entering kindergarten in Washington state in 2012 had an exemption, and the figure was 6.1 percent in Illinois and Vermont.
Our Seattle-based team of researchers has been investigating if there’s a valid way of identifying parents who are hesitant enough early on in their child’s life that they will accept fewer immunizations than is recommended. Knowing early whether a parent is hesitant and will under-immunize their child might be helpful to clinicians as they try to understand and lessen a parent’s vaccine concerns.
