Abstract
Objective: The objective was to compare estimates of childhood influenza vaccination across 7 consecutive influenza seasons based on 2 survey systems.
Methods: We analyzed data from the National Health Interview Survey (NHIS) and the National Immunization Survey-Flu (NIS-Flu) using Kaplan-Meier survival analysis to estimate receipt, based on parental report, of at least 1 dose of influenza vaccine among children aged 6 months to 17 years.
Results: We found no significant increasing trend in influenza vaccination coverage among children overall from 2012 to 2018 based on the NHIS or from 2012 to 2019 based on the NIS-Flu. We found 4 seasons with a significant increase in influenza vaccination coverage compared with the previous season (2012-2013 [NHIS, NIS-Flu], 2013-2014 [NIS-Flu], 2017-2018 [NHIS], and 2018-2019 [NIS-Flu]). As of the 2018-2019 season, based on NIS-Flu, influenza vaccination coverage was only 62.6%. Children with health conditions that put them at increased risk for complications from influenza had higher influenza vaccination coverage than children without these health conditions for all the seasons studied except 2014-2015. For all seasons studied, influenza vaccination coverage estimates for children were higher based on NIS-Flu data compared with NHIS data. Trends across seasons and differences in vaccination coverage between age groups were similar between the 2 surveys.
Conclusions: Influenza vaccination coverage among children appears to have plateaued. Only about half of the children in the United States were vaccinated against influenza. Improvements in measurement of influenza vaccination and development and review of strategies to increase childhood influenza vaccination coverage are needed.
