First seen Jul 24, 2026 ยท Last updated Jul 24, 2026

Summary

This trial tests whether a combination of practice education and quality improvement tools can help pediatric clinics in Tennessee increase the number of 2-year-olds who receive all recommended vaccines (the Combo 10 series). The study enrolls 8 clinics and uses a stepped-wedge design, meaning each clinic eventually receives the intervention. The goal is to see if this low-cost approach can reduce vaccination refusal and improve public health.
