Weekly Flu Vaccination Dashboard

About

The Weekly Influenza (Flu) Vaccination Dashboard is designed to share preliminary weekly in-season flu vaccination information, including preliminary vaccination coverage estimates and intent for vaccination, using a variety of data sources including telephone surveys, healthcare claims databases, electronic medical records, and immunization information systems (IISs). The Dashboard will be updated weekly as new data become available. These estimates might differ from CDC’s final flu vaccination coverage estimates published after the end of each season using different analytic methods or based on data sources not available during the season. Please email to share any feedback (VaxView@cdc.gov).

Data Summary

Data Updates

Data updates are scheduled each Wednesday during 11 AM – 1 PM ET. Data, visuals, and/or features may be changing and may not match their final state during this time.

Flu Vaccine Doses Distributed

Data and charts are available here.

Flu vaccine supply depends on private manufacturers who produce the vaccine.

Additional information on supply for this and previous seasons are available.

Child Flu Vaccination Coverage

Preliminary, within-season flu vaccination coverage estimates for children ages 6 months through 17 years are calculated using parent-reported information from the National Immunization Survey-Flu (NIS-Flu). Data and charts are available here.

CDC's final estimates for previous flu seasons are available.

Pregnant Women Flu Vaccination Coverage

Estimates of flu vaccination coverage for pregnant women 18–49 years are calculated using data from CDC's Vaccine Safety Datalink (VSD). VSD data include electronic health records from ten integrated health systems. Data and charts are available here.

Adults 18+ Flu Vaccination Coverage

Preliminary, within-season flu vaccination coverage estimates for adults 18 years and older are calculated using self-reported information from the National Immunization Survey-Adult COVID Module (NIS-ACM). Data and charts are available here.

CDC's final estimates for previous flu seasons are available.

Child and Adult Flu Vaccine Administration and Coverage (monthly)

These within-season, jurisdiction-level, vaccination coverage estimates for children 6 months–17 years and adults 18 years and older are based on IIS data submitted to CDC through the end of December 2024 by 49 immunization awardee jurisdictions. The coverage of some Pacific Island jurisdictions may reflect vaccination program activities aligned with regional virus circulation patterns (i.e., they may vaccinate on a different schedule than the continental U.S.). Data and charts are available here.

Adults 65+ Flu Vaccination Coverage (monthly)

Flu vaccination coverage among Medicare fee-for-service beneficiaries 65 years and older is assessed using data files from the Medicare Fee-For-Service administrative claims data managed by the Centers for Medicare & Medicaid Services. Data and charts are available here.

Adult Flu Vaccinations Administered

IQVIA measures flu vaccinations administered at retail pharmacies and American Medical Association (AMA) physicians' medical offices for adults 18 years and older, based on healthcare claims data. Data and charts are available here, with estimates available overall and by select age groups.

The Indian Health Service's (IHS) Influenza-like Illness Awareness System (IIAS) captures flu vaccination coverage among American Indian and Alaska Native (AI/AN) patients who received care in an IHS and in some Tribal or Urban Indian (I/T/U) healthcare facilities.

The health care personnel flu vaccine coverage is captured through the IHS National Immunization Reporting System (NIRS) and includes employees who work in IHS and in some tribal and urban healthcare facilities.

There may be gaps in both the IIAS and NIRS systems since not all I/T/U healthcare facilities report.

Data are available via Indian Health Service.
