Achieving Equity in Childhood Vaccination: A Mixed-Methods Study of Immunization Programs, Policies, and Coverage in 3 US States.

Variability persists in vaccination coverage and equity across states, race/ethnicity, and socioeconomic status despite decades of interventions. Vaccine stakeholders should use our findings to improve coverage and reduce disparities. Equitable improvements can be realized through policy change, data tracking/infrastructure improvements, and tailored interventions. Furthermore, local partners are critical in improving vaccine coverage and equitable interventions to disrupt disparities that long hold true for vaccine-preventable diseases.
