Protecting children, families, and communities against influenza.


It is recommended that all adults get an annual flu vaccine to protect themselves from flu and stop the spread of the virus to their families and communities.

Impact of Flu On Adults

Each flu season, anywhere from 9.3 million - 49 million people suffer with flu illnesses, between 140,000 – 960,000 people are hospitalized due to flu, and between 12,000 – 79,000 people die each year just in the U.S. The majority of people who bear the greatest burden of severe flu disease tends to be adults.

Between 12,000 – 79,000 deaths from flu in the U.S. every year

Ideally, adults should be vaccinated by the end of October. However, as long as flu viruses are circulating, vaccination should continue throughout flu season.

Dangers of Flu in Adults

Flu is a very unpredictable virus and while we can treat the symptoms, the virus must run its course. That’s why even healthy and active adults can suffer with serious illness and complications from flu. For adults who suffer with certain health conditions, whether those conditions are identified or not, the flu can pose an even more severe risk.  Learn more about the various health conditions that can elevate an individuals risk of complications from flu here.


An otherwise healthy adult may end up hospitalized and suffer from loss of income, increased medical bills and even permanent health consequences that could have been avoided.


Long term health effects of flu


Even months after recovering from flu, adults remain at an increased risk of heart attack, stroke or other health disabilities.

Benefits of Flu Vaccination in Adults:

Flu vaccination not only reduces our chances of suffering with a flu illness, but also reduces the likelihood of suffering with more serious flu outcomes.


Flu vaccination reduces risk of flu illnesses.

In seasons when the vaccine viruses is well matched to circulating strains, flu vaccine has been shown to reduce the risk of having to go to the doctor with flu by 40-60 percent. If you do happen to get sick despite being vaccinated, studies show that vaccination may reduce the severity of disease. 


Flu vaccination reduces the risk of flu-associated hospitalization.

In recent years flu vaccines have reduced the risk of flu-associated hospitalizations among adults by about 40%.

Flu-associated hospitalizations due to flu

A study showed that flu vaccination among adults from 2012 to 2015 reduced the risk of being admitted to an intensive care unit (ICU) with flu by 82%. And if you are hospitalized with flu, another study showed that vaccinated individuals were 59% less likely to be admitted to the ICU than those who had not been vaccinated.


Reduce the Spread of Influenza

Flu vaccination reduces the spread of flu.

Getting vaccinated helps ensure you don’t spread flu to others who are vulnerable to serious flu illness, like infants too young to be vaccinated, pregnant women, immunocompromised individuals, older family members or people with certain chronic health conditions.
