Flu Vaccine in Children: What the Experts Say

The CDC recommends yearly flu vaccines for most people ages 6 months and up. Children under 2 are at greater risk of having complications from the flu than older kids and adults. Children should get the vaccine by October of each year. Flu season is usually between November and May, with its peak in February.

The benefits of flu vaccine for children don't last as long as those of other vaccines. That's because the flu virus is always changing. Each year, the flu is a little different, so a new vaccine has to be prepared.

The first time your child younger than 9 gets a flu vaccine, he or she will need two doses, separated by at least a month. A child usually receives the vaccine in the leg or arm.

Flu vaccines are especially important for kids with certain diseases or conditions. These children may be at greater risk of serious complications related to the flu. It's especially important that children with any of the following conditions or treatments get the flu vaccine.

Side Effects of Flu Vaccines for Children

The side effects from flu vaccines for children are mild. They include:

  • Redness or soreness at the site of the injection
  • Low-grade fever
  • Aches

Remember that flu vaccines for children cannot give your child the flu. More serious side effects are very rare.

Allergic reactions are a risk with any medicine. Signs of allergic reaction to a flu vaccine include:

If you see any of these signs, get emergency help.

Flu vaccines for children may not be safe for everyone. Your pediatrician may not want to vaccinate your child if he or she:

  • Has had severe allergic reactions to past flu vaccines
  • Has ever had Guillain-Barré Syndrome, an immune system disorder
  • Is currently sick

It's long been advised that people with allergies to eggs should not get the flu shot. However, the American College of Allergy, Asthma and Immunology says the vaccine contains such a low amount of egg protein that it's unlikely to cause an allergic reaction in those with an egg allergy. If you have a severe egg allergy (anaphylaxis), talk to your doctor before getting the flu vaccine. Also, flu vaccines not made with the use of eggs are available.
