Increasing childhood influenza vaccination: a cluster randomized trial.

Background: Since the 2008 inception of universal childhood influenza vaccination, national rates have risen more dramatically among younger children than older children and reported rates across racial/ethnic groups are inconsistent. Interventions may be needed to address age and racial disparities to achieve the recommended childhood influenza vaccination target of 70%.

Purpose: To evaluate an intervention to increase childhood influenza vaccination across age and racial groups.
