Persistent Disparities in Immunization Rates for the Seven-Vaccine Series Among Infants 19–35 Months in the United States

Abstract

<b>Objective:</b> The seven-vaccine series protects infants from several preventable diseases, yet disparities in its use remain in the United States. <b>Methods:</b> We assessed the seven-vaccine immunization rate and its predictors in infants 19-35 months using the National Immunization Survey from 2009 to 2018. <b>Results:</b> The seven-vaccine series rate was 72.8%, well short of the healthy people 2020 target of 90%. African American infants, infants born to mothers with less than high school education, and infants in families with an income below poverty were less likely to get the complete series. <b>Conclusion:</b> Disparities still exist in protecting infants from preventable diseases in the United States.
