Weekly Cumulative Influenza Vaccination Coverage Map and Comparison Between 2025–26 and 2024–25 by Jurisdiction, Adults 18 Years and Older

Published by Centers for Disease Control and Prevention | U.S. Department of Health & Human Services | Catalog Last Checked: August 05, 2026 at 04:34 PM | Dataset Last Updated: August 03, 2026
• Weekly Influenza Vaccination Coverage Map and Comparison Between 2025-26 and 2024-25 among adults 18 Years and Older by Jurisdiction. • Weekly estimates of influenza vaccination coverage and intent for vaccination among adults are calculated using data from the National Immunization Surveys (NIS)-Fall Respiratory Virus Module (NIS-FRVM) (https://www.cdc.gov/nis/about/index.html). The NIS-FRVM is an ongoing random-digit-dial cellular telephone survey of households with adults 18 years and older. All estimates are based upon self-reported receipt of vaccination and month of that vaccination. • The NIS-FRVM data posted on the dashboard below are currently a few days behind the data that are posted on the Respiratory Illnesses Data Channel (https://www.cdc.gov/respiratory-viruses/data/index.html). This lag is due to the time it takes to review data by geographic and sociodemographic characteristics and summarize the findings.
