Influenza Vaccination Coverage, Children 6 months through 17 years, United States

Influenza vaccination coverage among children is assessed through the National Immunization Survey-Flu (NIS-Flu) annually, providing weekly influenza vaccination coverage estimates for children 6 months–17 years based upon parental report.

• NIS-Flu is a national random-digit-dialed cellular telephone survey of households conducted during the flu season (October-June).
• Additional information about final 2021-22 season estimates is available. Weekly estimates in this dashboard for the 2020-21 and earlier seasons may differ from final season estimates because of different methodologies.
• Figure 2A. Weekly Cumulative Influenza Vaccination Coverage*, by Flu Season and Selected Demographics, Children 6 Months—17 Years, United States, Data Source: NIS-Flu, Data are current through February 11, 2023.
• Figure 2B. Cumulative Influenza Vaccination Coverage*, by Week, Flu Season, and Race/Ethnicity, Children 6 Months—17 Years, Data Source: NIS-Flu, Data are current through February 11, 2023.
• Figure 2C. Weekly Cumulative Influenza Vaccination Coverage* and Comparison between Current and Previous Season**, by Jurisdiction, Children 6 Months—17 Years, United States Data Source: NIS-Flu Data are current through February 11, 2023.
• Figure 2D. Differences in Cumulative Influenza Vaccination Coverage by Race/Ethnicity, during 2021-22 and between 2020-2021 and 2021-2022, Children 6 Months—17 Years, United States Data Source: NIS-Flu Data are current through February 11, 2023.

^{* Week ending dates for prior seasons are aligned with the current season’s week ending dates. Sample size is insufficient to provide estimates by race/ethnicity by jurisdiction. Data for prior seasons for Figure 2D will be added in November.
**Interpretation of the difference between current minus previous season is based on the 95% confidence interval (CI) of the difference. The interpretation is “Similar to last season” if the 95% CI for difference overlaps with zero; “Lower than last season” if the entire 95% CI for the difference is below zero; and “Higher than last season” if the entire 95% CI for the difference is above zero.}
