Weekly Flu Vaccination Dashboard

Flu Vaccine Doses Distributed

For the 2024–25 season, as of September 28, 2024, 108.04 million doses of flu vaccine have been distributed in the United States. Data and charts are available here.

Flu vaccine supply depends on private manufacturers who produce the vaccine. Vaccine manufacturers have projected that they will supply the United States with 148 million doses of influenza vaccines for the 2024–25 season. These projections may change as the season progresses.

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

Child Flu Vaccination Coverage (NIS)

The summaries for the 2024-25 season will be populated as the data become available throughout the fall.

Pregnant Persons Flu Vaccination Coverage

Estimates of flu vaccination coverage for pregnant persons 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.

• Vaccination coverage among pregnant persons had decreased between 2019–20 and 2023–24 overall and in all race and ethnicity groups.

• As of October 5, 2024, 21.2% of pregnant persons had received a flu vaccine, compared with 20.8% during the same period in 2023.

• Vaccination coverage was highest among non-Hispanic Asian pregnant persons (32.3%) and lowest among non-Hispanic Black pregnant persons (14.5%).

All Adults Flu Vaccination Coverage (NIS-ACM)

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.

• As of October 5, 2024, 19.6% (95% Confidence Interval [CI] 17.8–21.4) of adults received a flu vaccination.
  • 27.5% (95% CI 25.4–29.7) reported they definitely will get a flu vaccine.
  • 22.2% (95% CI 20.1–24.3) reported they probably will or are unsure if they will get a flu vaccine.

• The percentage vaccinated varies by age:
  • 13.7% (95% CI 11.8–15.5) of adults 18–49 years, 18.1% (95% CI 15.0–21.1) 50–64 years, and 36.3% (95% CI 31.3–41.4) 65+ years.

• The percentage of adults who received a flu vaccination also varies by disability status, health insurance, race and ethnicity, sex, and urbanicity.

• The percentage of adults vaccinated varied by state, from 4.7% to 44.4%.

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

Jurisdiction Flu Vaccine Administration and Coverage (IIS)

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 September 2024 by 38 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.

• For children 6 months–17 years:
  • Among the currently reporting 31 state and city IIS jurisdictions, flu vaccination coverage among children 6 months–17 years ranged from 1.1% to 16.7%.
  • Among 7 reporting U.S. territorial and affiliated island jurisdictions, coverage ranged from 0.0% to 11.3%.

• For adults 18 years and older:
  • Among the currently reporting 31 state and city IIS jurisdictions, flu vaccination coverage among adults 18 years and older ranged from 3.2% to 13.8%.
  • Among 7 reporting U.S. territorial and affiliated island jurisdictions, coverage ranged from 0.0% to 4.5%.

Adults 65 Years and Older (Medicare Fee-for-service) Flu Vaccination Coverage

The summaries for the 2024-25 season will be populated as the data become available throughout the fall.

Adult Flu Vaccinations Administered in Pharmacies and Medical Offices

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.

• ~9.2 million fewer doses were administered in retail pharmacies and physicians' medical offices at the end of the 2023–24 season (63.1M), compared with the end of the pre-pandemic 2019–20 season (72.3M).

• For the 2024–25 season, as of September 21, 2024, an estimated 8.7 million doses of flu vaccine were administered in retail pharmacies.
  • This was ~1.1 million more doses than were administered by this same time point in the 2023–24 flu season.

• For the 2024–25 season, as of September 21, 2024, an estimated 3.3 million doses were administered in physicians’ medical offices.
  • This was ~1.2 million fewer doses than were administered by this same time point in the 2023–24 flu season. This may be partly related to lag in claims processing.

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.
