Should children get the nasal flu vaccine?

The CDC announced that the flu nasal spray is available for the 2021-2022 flu season. Learn which type of flu vaccine is best for your child.

If you are like many parents, the nasal spray flu vaccine sounds like an easy way to protect your child against the flu. You don't have to worry about your child's fear of needles or any tears or tantrums leading up to the shot.

However, in 2016, the Centers for Disease Control and Prevention (CDC) announced that the nasal mist flu vaccine was not as effective as the injectable flu vaccine, and physicians stopped offering it as an option. Then in 2018, the nasal flu vaccine came back on the market, and it's now available again for the 2021-2022 flu season.

What's the difference between the flu shot and nasal spray?

The flu shot is a vaccine that is injected using a needle. The standard flu vaccine uses inactivated or "dead" virus particles to cause your body to make antibodies to the flu virus. There are many different flu viruses, and each year, the vaccine is adjusted to protect against strains that are predicted to be the most common.

The nasal flu vaccine is a mist that is sprayed into your nose. The nasal spray contains four live flu viruses, as opposed to the inactivated viruses included in the standard flu shot. However, these viruses are weakened so that the nasal flu spray will not cause the flu. The CDC recommends the nasal mist flu vaccine for children aged 2 and up.

Flu shot vs nasal spray: Which is more effective?

In its guidelines for the 2018-2019 flu season, the American Academy of Pediatrics (AAP) said the injectable vaccine was the better option for children over the needle-free nasal spray. However, in their updated guidelines for the 2021-2022 flu season, the CDC and AAP do not state a preference for either the flu shot versus the nasal flu vaccine.

"In past years, the injectable form was preferred due to better protection, but this flu season, the flu mist has equal preference with the injectable vaccine," says Preeti Sharma, M.D., pulmonologist at Children's Health℠ and Associate Professor at UT Southwestern. "Still, in many cases, the flu nasal mist is not the best choice, especially for people with a history of lung diseases, or for anyone who is immunocompromised."

Parents should talk to their pediatrician about which flu vaccine is recommended for their child. Children must be 2 years of age or older to receive the nasal spray vaccine. The flu nasal spray is not recommended for anyone with chronic lung problems like asthma or cystic fibrosis, for children taking certain medications or for anyone with a compromised immune system. The CDC also notes that nasal congestion may limit the ability of the vaccine to reach the nasal lining.

Whether you opt for the flu shot or nasal spray vaccine, flu season is still coming. Protecting your child from the influenza virus is a very important part of making sure your family stays healthy.

"Every person 6 months of age or older should be immunized against the flu virus," says Dr. Sharma. "The flu can be very dangerous, particularly for children who are considered a high-risk population for influenza."

Flu facts: Why you should protect your child

  • On average, 8% of people in the U.S. come down with the flu each year.
  • Children are most likely to get sick from the flu.
  • Pneumonia is one of the most serious complications of an influenza infection.
  • According to the CDC, 188 children died of influenza in the U.S. during the 2019-2020 flu season. The season prior, 144 pediatric deaths were reported.
  • The best protection against the seasonal flu is the flu vaccine, and it's encouraged for all people over 6 months of age.

When and where should my child get their flu shot?

Usually, it's best to get the flu shot in early fall. It can take up to two weeks for the antibodies to develop after the vaccine is administered, so it's most effective to get the flu shot before flu season hits. For the 2021-2022 flu season, the Centers for Disease Control and Prevention (CDC) recommends getting the flu shot before the end of October, if possible.

If you miss the early window for getting the flu vaccine, Dr. Sharma advises it's better late than never. Some flu seasons stretch out for months. Getting the flu vaccine at any time will help reduce your family's risk of getting sick and reduce the chance of flu-related complications.

Although getting a flu vaccine has become more convenient and is available at more places than ever before, if you can, the best place to turn for a vaccination should be your child's primary health care provider. They best understand your child's medical history and specific needs and can offer flu vaccination as part of their ongoing comprehensive care plan.

Can you get the flu vaccine at the same time as the COVID‑19 vaccine?

Flu vaccines and COVID‑19 vaccines can be given at the same time per CDC guidelines. The COVID‑19 vaccine is currently approved for anyone 12 years and older.

How to protect your child from getting the flu

Of course, vaccination is just the first step in the battle against the flu. It's important to keep in mind other ways that you can help keep your family flu-free:

  • Practice good hand hygiene
  • Cover your nose and mouth when you cough or sneeze
  • Avoid close contact with sick people
  • Disinfect surfaces
