Influenza Vaccination Coverage, Adults

• The National Immunization Survey-Adult COVID Module (NIS-ACM) was launched in April 2021 among adults 18 years and older. The survey was used to monitor COVID-19 vaccination uptake and confidence in vaccination among adults and included questions about influenza vaccination.
• The NIS-ACM adult flu vaccination coverage estimates are based on interviews conducted during each approximate monthly analysis period and can increase or decrease over time due to random sampling variation. This will happen more frequently for smaller sample sizes (e.g., when stratifying by multiple characteristics).

^*Data for Guam are only available from April-June 2022 and the data for U.S. Virgin Islands are only available from April-December 2021. National estimates include 50 states, Washington D.C., and Puerto Rico and when available, U.S. Virgin Islands and/or Guam.

^‡Estimates are not reported if they do not meet the National Center for Health Statistics Data Presentation Standards [1.5 MB, 22 Pages].

†In the table in Figure 4A, a blank cell in the ‘Coverage’ column represents suppressed or missing data and a ‘.’ in the ‘95% CI’ column represents CIs that were not calculated due to missing or suppressed data.

^ The ‘Other/Multiple Races, Non-Hispanic’ category includes American Indian/Alaskan Native, non-Hispanic, Asian, non-Hispanic, Pacific-Islander/Hawaiian Native, non-Hispanic, and persons who selected ‘Other’ and multiple races. Therefore, the ‘Other/Multiple Races, Non-Hispanic’ jurisdiction-level estimates on the map should not be compared with the ‘Other/Multiple Races, Non-Hispanic’ national estimates in the table.
