Weekly National Flu Vaccination Dashboard

This dashboard and data will be updated in September 2021.​

Weekly National Flu Vaccination Dashboard logo

CDC’s Immunization Services Division (ISD) has developed this new Weekly National Influenza Vaccination Dashboard, an exploratory data product, in order to share some preliminary, within-season, weekly influenza vaccination data and coverage estimates using existing and new data sources. The data will be updated weekly or monthly, depending on the data source, throughout the 2020-2021 influenza season; other data sources will be added as they become available. All data are preliminary and will be updated as more data are received.

Key Points
  1. As of February 26, 2021, 193.8 million doses of flu vaccine have been distributed in the United States. This is the highest number of flu doses distributed in the United States during a single influenza season.
  2. Current flu vaccination coverage among children is estimated to be 58.2% as of the week ending April 17, 2021 (MMWR week 15), lower than the 62.3% coverage estimated during the week ending April 18, 2020  (MMWR 15) in 2020.
    • Current season’s coverage is lower for all race/ethnicity groups compared with same time last year, with the largest drop of 8 percentage points among Black, non-Hispanic children.
    • Current season’s coverage for Black, non-Hispanic children is lowest at 48.0%, which is 12 percentage points lower than White, non-Hispanic children (60.2%).
  3. For pregnant persons, estimated flu vaccination coverage at the end of March 2020 was 61.3% compared with 65.5% for the same time period during 2019.
    • Coverage for 2020-21 season for Black, non-Hispanic pregnant persons (36.5%) was nearly 25 percentage points lower compared with White, non-Hispanic pregnant persons (61.3%).
    • Coverage for all race/ethnicity groups was lower for 2020-21 compared with 2019-20; the greatest difference was for Black, non-Hispanic persons (36.5% for 2020-21 compared with 43.5% for 2019-20)
  4. Preliminary available coverage estimates suggest flu vaccination uptake this season among all children and pregnant persons is lower than last season. Also, there is a disparity between vaccination coverage (comparing both during this season and compared with last season) among White, non-Hispanic children compared with Black, non-Hispanic children and Hispanic children. Flu vaccination uptake is lowest among Black, non-Hispanic pregnant persons compared with all other racial groups.
  5. For vaccinations among all adults:
    • The latest data from CDC sponsored biweekly questions about influenza vaccination, from the  IPSOS Knowledge Panel Omnibus survey fielded February 05-07, 2021, indicate that:
      • 55% of all adults had received flu vaccine. These estimates are higher than the previous season’s (2019-2020) coverage estimates for adults, which were 45% by the end of January 2020 and 48% by the end of May 2020.
      • Coverage increased with age, from 45% for people ages 18-49, to 60% for people ages 50-64, and 80% for people age ≥65 years.
      • Coverage was lower among non-Hispanic Black adults compared to non-Hispanic White adults (50% vs. 58%).
    • Flu coverage among Medicare fee-for-service beneficiaries aged ≥65 years was 56.5% at the end of March 2021 (MMWR Week 12, 2020-2021) compared with 56.0% in March 2020 (MMWR Week 12, 2019-2020); more vaccinations were administered earlier in the 2020-21 season compared with 2019-2020 (coverage was 48.1% by the end of October 2020 (MMWR Week 44, 2020-2021) compared with 38.2% by the end October 2019) (MMWR Week 43, 2020-2021).
      • March 2021 represents the minimum coverage as some claims data are still being processed.
    • As of MMWR week 14 (ending April 10, 2021), an estimated 47.7 million adult flu vaccinations had been administered in pharmacies compared with 35.4 million for the same MMWR week during 2020 (35% higher in 2021).
    • As of MMWR week 14 (ending April 10, 2021), 32.8  million adult flu vaccinations were reported to have been administered in physician medical offices compared with 36.9 million for  the same MMWR week in 2020 (11% lower in 2021).

Based on the omnibus survey data, it appears flu vaccination coverage among adults was higher by early February during the current season than during prior seasons, indicating that more than half of adults had been vaccinated by early February. Given potential limitations of these rapid surveys and underlying panels that might lead to over-estimation of vaccination coverage, confirmation with estimates from other surveys (to be available later) is needed.
