Nasal Flu Vaccine for Children


Several types of viruses cause the flu. The viruses change over time, so new vaccines are made each year. Your child should get the vaccine as soon as recommended each year, usually in September or October. The vaccine begins to protect your child about 2 weeks after he or she gets it. The nasal flu vaccine can be given to children who are 2 years or older. The flu vaccine may cause mild symptoms, such as a fever, headache, and muscle aches. Your child may still get the flu after he or she receives the vaccine.


Call your local emergency number (911 in the US) if:

  • Your child's mouth and throat are swollen.
  • Your child is wheezing or has trouble breathing.
  • Your child has chest pain or his or her heart is beating faster than normal.
  • Your child feels like he or she is going to faint.

Return to the emergency department if:

  • Your child's face is red or swollen.
  • Your child has hives that spread over his or her body.

Call your child's doctor if:

  • Your child feels weak or dizzy.
  • You have questions or concerns about your child's flu vaccine.

Do not give your child aspirin for 4 weeks

after he or she gets the nasal flu vaccine. Talk to your child's healthcare providers about safe medicines if needed to control a health condition.

Follow up with your child's doctor as directed:

Write down your questions so you remember to ask them during your child's visits.
