Protect Yourself From the Flu

No, flu vaccines can’t cause flu. Flu vaccines given with a needle are made with inactivated (dead) viruses or with only a single protein from the flu virus. The nasal spray vaccine contains live viruses that are attenuated (weakened) so that they won’t cause illness.

There are many flu vaccine options to choose from. The most common is the flu shot which is given with a needle, usually in the arm. A nasal spray flu vaccine is also available for healthy, non-pregnant individuals ages 2 through 49. There’s also a high-dose flu vaccine option recommended for people over age 65. For those with egg allergies, there are egg-free flu vaccines available.

If you have questions about which vaccine is best for you, talk to your doctor or other health care professional.

No. Flu can be a serious disease, particularly among young children, older adults and people with certain chronic health conditions, such as asthma, heart disease or diabetes. Any flu infection can carry a risk of serious complications, hospitalization or death, even among otherwise healthy children and adults.

Yes. Immune protection from vaccination declines over time, so an annual vaccination is needed to get the best protection against flu. Additionally, flu viruses are constantly changing, so the vaccine composition is reviewed each year and updated as needed based on which influenza viruses are making people sick.

Some people report having mild side effects after flu vaccination. The most common are soreness, redness, tenderness or swelling where the shot was given. Reactions may also include low-grade fever, headache and muscle aches. If these occur, they usually begin soon after vaccination and last one to two days.

Side effects from the nasal spray flu vaccine may include runny nose, wheezing, headache, vomiting, muscle aches, fever, sore throat and cough. If these occur, they usually begin soon after vaccination and are mild and short-lived. The most common reactions people have to flu vaccines are considerably less severe than the symptoms caused by actual flu illness.

There are several reasons why someone might get flu symptoms, even after they’ve been vaccinated against flu:

• People can become ill from other respiratory viruses such as rhinoviruses, which are associated with the common cold, cause symptoms similar to flu, and also spread and cause illness during flu season. The flu vaccine only protects against flu, not other illnesses.
• It’s possible to be exposed to flu viruses shortly before getting vaccinated or during the two-week period that it takes the body to develop immune protection after vaccination. This exposure may result in a person becoming ill with flu before protection from the vaccination takes effect.
• People may have been exposed to a flu virus that’s very different from the viruses the vaccine is designed to protect against. The ability of a flu vaccine to protect a person depends largely on the similarity or match between the viruses selected to make the vaccine and those spreading and causing illness. There are many different flu viruses that spread and cause illness.
• Flu vaccines vary in how well they work and some people who get vaccinated still get sick. However, when that happens, vaccination has been shown to reduce the severity of illness in those people who get vaccinated but still get sick.

There’s no evidence that getting a flu vaccination increases your risk of getting COVID-19.
