Influenza (flu) is a contagious respiratory illness caused by flu viruses. It can cause mild to severe illness, and at times can lead to death.

The best way to prevent flu is with a flu vaccine.

Your Flu Shot is the First and Most Important Step to Fight the Flu.

Reducing illness and hospitalization from the flu helps keep everyone safer.

  • Stay home if you're sick
  • Cover coughs and sneezes
  • Wash your hands
  • Wear a face covering if social distancing isn't possible.

Save lives by reducing the spread of viruses.

Getting a flu vaccine during 2020-2021 is more important than ever. Flu vaccination is also especially important for children. Children younger than 5 years old–especially those younger than 2– are at high risk of developing serious flu-related complications. CDC recommends an annual flu vaccine for everyone 6 months and older.

Influenza (flu) is a contagious respiratory illness caused by flu viruses. It can cause mild to severe illness, and at times can lead to death. The best way to prevent the flu is to get a flu vaccine each fall. Children 6 to 23 months of age are considered at high-risk for flu complications and should be immunized. Consult your health care provider for more information regarding childhood flu immunization recommendations.

CDC recommends use of injectable influenza vaccines (including inactivated influenza vaccines and recombinant influenza vaccines) during 2020–2021.

The "flu shot"—an inactivated vaccine (containing killed virus) that is given with a needle, usually in the arm. The flu shot is approved for use in people older than 6 months, including healthy people and people with chronic medical conditions.

The regular seasonal flu shot is "intramuscular" which means it is injected into muscle (usually in the upper arm). It has been used for decades and is approved for use in people 6 months of age and older, including healthy people, people with chronic medical conditions and pregnant women. Regular flu shots make up the bulk of the vaccine supply produced for the United States.

The high-dose vaccine is for people 65 and older which also is intramuscular. This vaccine was first made available during the 2010–2011 season.

About two weeks after vaccination, antibodies that provide protection against influenza virus infection develop in the body. Flu vaccine is the best way to prevent infection, but everyone must be re-vaccinated each year because the flu viruses change each year.

Get your flu shot—the first and most important step to fight the flu.

Keep Vaccine Between You and Disease

  • Cover your mouth and nose with a tissue when you cough or sneeze. If you don’t have a tissue, cough or sneeze into your upper sleeve or elbow, not your hands.
  • Wash your hands often with soap and water. If you don’t have soap and water, use an alcohol-based hand sanitizer.
  • Try not to touch your face with unwashed hands.

  • Clean and disinfect frequently touched surfaces.
  • Don’t touch or shake hands with people who are sick.

  • Stay home when you’re sick, and keep your children home when they’re sick.
