Abstract
- Introduction: Being up-to-date with all recommended vaccines is needed to protect children from vaccine preventable diseases. Understanding vaccination patterns is needed to develop messaging and strategies to increase vaccination uptake and confidence.<br />Methods: Data from the 2011 to 2021 National Immunization Surveys was used to assess trends and disparities in vaccination patterns, zero vaccination status, and up-to-date status of U.S. children by 19-35 months.<br />Results: From 2011 to 2021, adherence to the recommended schedule using the stringent definition increased from 35.7 % to 52.2 % (p < 0.01), adherence to the alternate schedule decreased from 28.2 % to 15.1 % (p < 0.01), and proportion of children who were not up-to-date decreased from 49.0 % to 33.3 % (p < 0.01). However, the proportion of children who had zero vaccinations did not change from 2011 (0.9 %) to 2021 (0.9 %; p = 0.08). In 2021, children 19-23 months were less likely to follow the recommended schedule than children 24-29 months (49.2 % compared to 56.4 %, p < 0.01). Adherence to the recommended schedule among children 19-23 months decreased in 2021 compared to 2020 overall and for some subpopulations (e.g. those with non-Hispanic (NH) Black parents (33.2 % compared to 44.9 %, p < 0.01). Furthermore, it was lowest among children of NH Black parents living at or below the federal poverty level (31.2 %) compared to their respective NH White counterparts (43.6 %, p < 0.01).<br />Conclusions: While there were overall increases in adherence to the recommended schedule from 2011 to 2021, a sustained catch-up program is needed to prevent missed vaccinations and achieve equitable vaccination coverage for all children.<br />Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper.<br /> (Copyright © 2024 Elsevier Ltd.
