The single best way to protect against the flu is to get vaccinated each year.
There are two types of vaccines:
About 2 weeks after vaccination, antibodies that provide protection against influenza virus infection develop in the body.
When to Get Vaccinated
October or November is the best time to get vaccinated, but you can still get vaccinated in December and later. Flu season can begin as early as October and last as late as May.
Who Should Get Vaccinated
In general, anyone who wants to reduce their chances of getting the flu can get vaccinated. However, it is recommended by ACIP that certain people should get vaccinated each year. They are either people who are at high risk of having serious flu complications or people who live with or care for those at high risk for serious complications. During flu seasons when vaccine supplies are limited or delayed, ACIP makes recommendations regarding priority groups for vaccination.
People who should get vaccinated each year are:
It should be noted that vaccination with the nasal-spray flu vaccine is always an option for healthy persons aged 5-49 years who are not pregnant.
Who Should Not Be Vaccinated
There are some people who should not be vaccinated without first consulting a physician. These include
The ability of flu vaccine to protect a person depends on the age and health status of the person getting the vaccine, and the similarity or "match" between the virus strains in the vaccine and those in circulation. Testing has shown that both the flu shot and the nasal-spray vaccine are effective at preventing the flu.
Vaccine Side Effects (What to Expect)
Different side effects can be associated with the flu shot and LAIV.
The flu shot: The viruses in the flu shot are killed (inactivated), so you cannot get the flu from a flu shot. Some minor side effects that could occur are
LAIV: The viruses in the nasal-spray vaccine are weakened and do not cause severe symptoms often associated with influenza illness. (In clinical studies, transmission of vaccine viruses to close contacts has occurred only rarely.)
In children, side effects from LAIV can include

There are two types of vaccines:
- 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 nasal-spray flu vaccine—a vaccine made with live, weakened flu viruses that do not cause the flu (sometimes called LAIV for “Live Attenuated Influenza Vaccine”). LAIV is approved for use in healthy people 5 years to 49 years of age who are not pregnant.
About 2 weeks after vaccination, antibodies that provide protection against influenza virus infection develop in the body.

People who should get vaccinated each year are:
- People at high risk for complications from the flu, including:
- Children aged 6 months until their 5th birthday,
- Pregnant women,
- People 50 years of age and older, and
- People of any age with certain chronic medical conditions;
- People who live in nursing homes and other long term care facilities.
- People who live with or care for those at high risk for complications from flu, including:
- Household contacts of persons at high risk for complications from the flu (see above)
- Household contacts and out of home caregivers of children less than 6 months of age (these children are too young to be vaccinated)
- Healthcare workers.
It should be noted that vaccination with the nasal-spray flu vaccine is always an option for healthy persons aged 5-49 years who are not pregnant.
Who Should Not Be Vaccinated
There are some people who should not be vaccinated without first consulting a physician. These include
- People who have a severe allergy to chicken eggs.
- People who have had a severe reaction to an influenza vaccination in the past.
- People who developed Guillain-Barré syndrome (GBS) within 6 weeks of getting an influenza vaccine previously.
- Influenza vaccine is not approved for use in children less than 6 months of age.
- People who have a moderate or severe illness with a fever should wait to get vaccinated until their symptoms lessen.

Different side effects can be associated with the flu shot and LAIV.
The flu shot: The viruses in the flu shot are killed (inactivated), so you cannot get the flu from a flu shot. Some minor side effects that could occur are
- Soreness, redness, or swelling where the shot was given
- Fever (low grade)
- Aches
LAIV: The viruses in the nasal-spray vaccine are weakened and do not cause severe symptoms often associated with influenza illness. (In clinical studies, transmission of vaccine viruses to close contacts has occurred only rarely.)
In children, side effects from LAIV can include
- runny nose
- headache
- vomiting
- muscle aches
- fever
- runny nose
- headache
- sore throat
- cough
