Note: On February 26, 2015, the Advisory Committee on Immunization Practices (ACIP) voted on its annual influenza vaccine recommendations. For 2015-2016, ACIP recommends annual influenza vaccination for everyone 6 months and older with either LAIV or IIV, with no preference expressed for either vaccine when either one is otherwise appropriate. More information on this vote is available at the CDC Newsroom. The LAIV content on this web page will be updated after the 2015-2016 recommendations are approved by the CDC Director and published in the MMWR.
Children 6 months and older should get an annual influenza (flu) vaccine. A flu vaccine is the best way to prevent the flu. Some flu vaccines come as a “shot” and some as a “nasal spray.” While the flu shot and the nasal spray vaccine both protect against the flu, there is evidence that the nasal spray vaccine may work better in younger children than a regular flu shot. CDC now recommends the nasal spray vaccine for healthy children 2 through 8 years old when it is available.
Each year, many children get sick with the flu; some are hospitalized and some die. Young children are the most likely to get sick with the flu. Children younger than 5 years are at high risk of getting serious flu complications. Vaccinating your child is the best way to protect them.
Recent studies suggest that the nasal spray flu vaccine may work better than the flu shot in younger children. Specifically in these studies, the nasal spray flu vaccine prevented about 50% more cases of flu than the flu shot in younger children.
If the nasal spray vaccine is not immediately available, get the flu shot for your child to protect them from the flu. Don’t delay vaccination if you can’t find nasal spray flu vaccine.
Typically, there are more flu shots and a smaller amount of nasal spray flu vaccines. If the nasal spray flu vaccine is not available or is not appropriate for your child, the flu shot is recommended.
No. Some children 2 through 8 years old should not get a nasal spray vaccine. This includes:
- Children who are getting aspirin therapy, or taking medicines that contain aspirin;
- Children who have a weakened immune system (immunosuppression);
- Children with a history of egg allergy;
- Children 2 through 4 years old who have had asthma or wheezing during the last 12 months;
- Children who have taken influenza antiviral medications (for example, Tamiflu® or Relenza®) within the last 48 hours.
These children may be able to get a flu shot instead.
There are other precautions for the nasal spray vaccine:
- Children with asthma who get the nasal spray may have an increased risk of wheezing
- The safety of the nasal spray vaccine in children with other health conditions that put them at increased risk of serious flu complications (e.g., diabetes, heart disease, neurological conditions, etc.) has not been established.
Check with your doctor or another health care professional if you have questions about which vaccine your child should get.
CDC does not recommend one vaccine over the other for children older than 8 years (that is, children age 9 years and older).
Children 6 months to 2 years of age should get a flu shot.
All nasal spray flu vaccines are made to protect against four flu viruses: an influenza A (H1N1) virus, an influenza A (H3N2) virus, and two influenza B viruses.
To find out what types of flu vaccines are offered in your area, call your doctor, pharmacy, or other local health facility; or use the HealthMap Vaccine Finder.
Regardless of the type of flu vaccine your child gets, some children up to 8 years of age will need 2 doses of flu vaccine to be fully protected. Usually this will apply to children getting a flu vaccine for the first time. The two doses should be given at least 28 days apart. Your child’s doctor can tell you whether your child needs two doses.
No. Whether your child’s first dose is a nasal spray vaccine or a flu shot, their second dose can be either one of the two vaccines.
No. While the nasal spray flu vaccine does contain live viruses (unlike the flu shot, which contains killed viruses), the viruses in the nasal spray vaccine are weakened and cannot cause flu illness. The flu shot cannot cause flu illness either.
The nasal spray flu vaccine can be given to people with minor illnesses (e.g., diarrhea or mild upper respiratory tract infection with or without fever). However, if your child has nasal congestion (a “stuffy nose”), your doctor may suggest delaying vaccination until the nasal congestion has improved.
As with all flu vaccines, the effectiveness of nasal spray flu vaccine can vary, depending on a number of factors, including the age and health of the person being vaccinated and how similar the viruses used to make the vaccine are to the viruses that are circulating. Some studies have shown, however, that the nasal spray flu vaccine may work better in younger children than the flu shot.
In children, side effects can include runny nose, headache, wheezing, vomiting, muscle aches, and fever. These side effects can sometimes be mistaken for the flu, however, they are usually mild and short-lasting, especially when compared to flu illness.
