Influenza vaccination rates among children remain lower than other pediatric and adolescent vaccines.1,2 Many variables may affect whether a child is vaccinated against influenza.3 However, to what extent, if any, the severity of an influenza season and either current or prior year’s vaccine effectiveness (VE) may affect vaccination rates has yet to be studied, to our knowledge. This information may be important in understanding how to message severity and VE data to parents. Therefore, using publicly available data, we examined the associations of seasonal influenza severity as well as current and prior year’s VE with yearly vaccination rates within age groups.
