Health Equity and Flu
Influenza (flu) can be serious and can lead to hospitalization and death; however, certain groups of people, including certain racial and ethnic minorities experience an unequal burden of severe flu outcomes. Long standing social and health inequities likely contribute to this.
More Serious Flu Outcomes
Black, Hispanic, and American Indian and Alaska Native (AI/AN) people have had consistently higher rates of severe flu outcomes, including hospitalization and ICU admission from 2009 to 2019.
Compared with White people, age-adjusted flu hospitalization rates were:
- Nearly 2 times higher among Black persons
- 1.3 times higher among AI/AN persons
- 1.2 times higher among Hispanic or Latino persons
Flu-related ICU admission rates were:
- 1.7 times higher among Black persons
- 1.4 times higher among AI/AN persons
- 1.1 times higher among Hispanic or Latino persons
People died in the hospital from flu at similar rates across all races and ethnicities during 2009-2019.
Disparities in flu outcomes were greatest in the youngest age groups, particularly among children (0-4 years old). Compared with White children 0-4 years of age, hospitalization, intensive care unit (ICU), and in-hospital death rates were:
- 3.0–3.5 times higher among non-Hispanic American Indian or Alaska Native children
- 2.2–3.4 times higher among non-Hispanic Black children
- 1.9–3.0 times higher among Hispanic or Latino children
- 1.3–4.4 times higher among non-Hispanic Asian or Pacific Islander children.
These estimates and the methodologies used to calculate them are published in JAMA Network Open and information about the Influenza Hospitalization Surveillance Network (FluSurv-NET) is also available.
Flu Vaccination is the Best Protection. Other Preventive Actions Can Also Help.
A flu vaccine is the best way to protect against flu and its potentially serious complications. In addition to reducing risk of flu illness, flu vaccination has been shown in several studies to reduce severity of illness in people who get vaccinated but still get sick with flu. That means vaccinated people could be less likely to be hospitalized with flu or less likely to be admitted to the ICU with flu. More information is available at What are the benefits of flu vaccination?. CDC recommends that everyone 6 months and older get a seasonal flu vaccine each year, ideally by the end of October. In addition to getting a flu vaccine, everyone should take everyday preventive actions, including avoiding people who are sick, covering coughs, and washing hands often.
Inequities in Vaccination Persist
Since 2010, flu vaccination coverage has been consistently lower among Black, Hispanic, and AI/AN adults. During the 2021–2022 season, flu vaccination coverage was:
- 54% among White adults
- 54% among Asian adults
- 42% among Black adults
- 41% among AI/AN adults and
- 38% among Hispanic adults
During the 2021–2022 season, among children (6 months–17 years), flu vaccination coverage was:
- 73% among Asian children
- 57% among White children
- 59% among Hispanic or Latino children
- 52% among Black children and
- 56% among AI/AN children
Causes of Disparities
There are likely several factors contributing to disparities in flu vaccination, many of which are rooted in health and societal inequities. These include but are not limited to:
- lack of access to health care and insurance,
- higher prevalence of underlying medical conditions,
- missed opportunities to vaccinate (healthcare providers may be missing opportunities to vaccinate people during routine medical appointments),
- misinformation about vaccination, and
- distrust of medical institutions.
In addition to disparities in vaccine uptake, there are likely other factors contributing to worse outcomes for some groups. Racism and prejudice are also known to worsen inequalities. Identifying and responding to these inequities is important for reducing health disparities.

CDC’s Commitment to Health Equity and Reducing Disparities
Increasing equitable vaccine uptake requires addressing the range of reasons why people do not get vaccinated. Over the past two years, CDC has begun two programs to address barriers to and raise awareness about the importance of flu vaccination, specifically among people from racial and ethnic minority groups. These include the Partnering for Vaccine Equity (P4VE) program and a targeted flu vaccination campaign. Using proven measures may help increase vaccination among people from racial and ethnic minority communities.

CDC is also continuing to collect data to better understand how racial and ethnic minorities are disproportionately impacted by flu-related hospitalization.
