Monthly Cumulative Number and Percent of Children 6 Months-17 Years and Adults 18 Years and Older Who Received 1+ Influenza Vaccination Doses and Comparison Between 2025–26 and Three Previous Seasons, by Jurisdiction, United States
Description: •Monthly Cumulative Percent of Persons Who Received 1+ Influenza Vaccination Doses and Comparison Between 2025–26 and Three Previous Seasons, by Jurisdiction, United States.
• Influenza (flu) vaccination coverage for children and adults is assessed through U.S. jurisdictions’ Immunization Information Systems Resources (IIS) data, submitted from jurisdictions to CDC monthly, in aggregate, by age group (https://www.cdc.gov/iis/about/).
• Monthly estimates shown are cumulative, reflecting all persons vaccinated from July 1 through a given month of that flu season.*,† Cumulative estimates include any historical data reported since the previous submission. National estimates are not presented since not all U.S. jurisdictions are currently reporting their IIS data to CDC. Jurisdictions reporting data to CDC include U.S. states, some localities, and territories.

Monthly Cumulative Number and Percent of Persons Who Receive ≥1 Influenza Vaccination Doses and Comparison Between 2023-2024 and Two Previous Seasons, by Jurisdiction, United States
Description: Monthly Cumulative Number and Percent of Persons Who Receive ≥1 Influenza Vaccination Doses and Comparison Between 2023-2024 and Two Previous Seasons, by Jurisdiction, United States • Influenza vaccination coverage for children and adults is assessed through U.S. jurisdictions’ Immunization Information Systems (IIS) data, submitted from jurisdictions to CDC monthly in aggregate by age group. More information about the IIS can be found at https://www.cdc.gov/vaccines/programs/iis/about.html. • Influenza vaccination coverage estimate numerators include the number of people receiving at least one dose of influenza vaccine in a given flu season, based on information that state, territorial, and local public health agencies report to CDC. Some jurisdictions’ data may include data submitted by tribes. Estimates include persons who are deceased but received a vaccination during the current season. People receiving doses are attributed to the jurisdiction in which the person resides unless noted otherwise. Quality and completeness of data may vary across jurisdictions. Influenza vaccination coverage denominators are obtained from 2020 U.S. Census Bureau population estimates. • Monthly estimates shown are cumulative, reflecting all persons vaccinated from July through a given month of that flu season. Cumulative estimates include any historical data reported since the previous submission. National estimates are not presented since not all U.S. jurisdictions are currently reporting their IIS data to CDC. Jurisdictions reporting data to CDC include U.S. states, some localities, and territories. • Because IIS data contain all vaccinations administered within a jurisdiction rather than a sample, standard errors were not calculated and statistical testing for differences in estimates across years were not performed. • Laws and policies regarding the submission of vaccination data to an IIS vary by state, which may impact the completeness of vaccination coverage reflected for a jurisdiction. More information on laws and policies are found at https://www.cdc.gov/vaccines/programs/iis/policy-legislation.html. • Coverage estimates based on IIS data are expected to differ from National Immunization Survey (NIS) estimates for children (https://www.cdc.gov/flu/fluvaxview/dashboard/vaccination-coverage-race.html) and adults (https://www.cdc.gov/flu/fluvaxview/dashboard/vaccination-adult-coverage.html) because NIS estimates are based on a sample that may not be representative after survey weighting and vaccination status is determined by survey respondent rather than vaccine records or administrations, and quality and completeness of IIS data may vary across jurisdictions. In general, NIS estimates tend to overestimate coverage due to overreporting and IIS estimates may underestimate coverage due to incompleteness of data in certain jurisdictions.

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