Flu is a serious disease, caused by influenza viruses, that can lead to hospitalization and even death. Every flu season is different, and the substantial health impacts can vary widely from season to season, with some flu seasons being worse than others. Your best defense is vaccination, which provides protection from flu and its potential complications.
Flu vaccines are approved by the U.S. Food and Drug Administration to prevent influenza, and they provide important benefits. The Centers for Disease Control and Prevention estimate that during the 2021-22 flu season there were:
8 million to 13 million flu illnesses.
3.7 million to 6.1 million flu-related medical visits.
82,000 to 170,000 flu-related hospitalizations.
5,000 to 14,000 flu-related deaths.
Flu vaccination prevents millions of flu-related illnesses and visits to a health care professional. For example, according to the CDC, during the 2019-2020 influenza season, flu vaccination prevented an estimated 7.5 million influenza illnesses, 3.7 million influenza-associated medical visits, 105,000 influenza-associated hospitalizations, and 6,300 influenza-associated deaths.
COVID-19 and Flu
It’s likely that flu viruses and the virus that causes COVID-19 will continue to circulate together in fall and winter. The flu vaccine does not prevent COVID-19. The FDA has approved two vaccines for the prevention of COVID-19 and issued emergency use authorizations (EUAs) for other vaccines for the prevention of COVID-19.
Flu vaccines are approved by the FDA for the prevention of influenza disease and to protect against four different virus strains of influenza. Getting vaccinated to prevent this disease can help keep you out of the doctor’s office for a sick visit and preserve health care resources for patients with other diseases and medical conditions. The FDA plays a key role in ensuring that safe and effective flu vaccines are available every flu season.
Flu viruses are spread by droplets when people infected with the flu cough, sneeze, or talk. Flu may also be spread when a person touches a surface or object that has flu viruses on it and then touches their own mouth, nose, or eyes.
A Flu Vaccine Is the Best Prevention
Flu seasons and their severity are unpredictable. Annual vaccination is the best way to prevent influenza in people ages 6 months and older.
An annual vaccination to prevent flu is the best way to reduce the risk of getting the flu and spreading it to others. When more people get vaccinated, it is less likely that the flu viruses will spread through a community.
The vaccine typically changes each year and contains the four flu virus strains that are expected to circulate and cause illness in the U.S. during the upcoming flu season. The effectiveness of influenza vaccines varies depending on several factors, such as the age and health of the recipient, the types of circulating influenza viruses, and the degree of similarity between circulating viruses and those included in the vaccine.
The flu vaccine will trigger your immune system to produce antibodies to protect against influenza disease — it will not make you sick with the flu. It can take about two weeks after vaccination for antibodies to develop in the body.
