What is the nasal flu vaccine?

This vaccine is sprayed into your child's nose to help prevent influenza (the flu). The flu is caused by a virus. The virus spreads through direct contact with someone who has the flu. For example, a person with the virus on his or her hands can spread it by shaking hands with someone. Several types of viruses cause the flu. The viruses change over time, so new vaccines are made each year. 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.

When should my child get a flu vaccine?

Your child should get the vaccine as soon as recommended each year, usually starting in September or October. Children 6 months through 8 years old may need 2 doses. The 2 doses should be given at least 4 weeks apart. The second dose should be given by the end of October. Your child can then usually receive 1 dose each year. Your child's healthcare provider will tell you if your child needs more than 1 dose for any reason.

What should I tell my child's doctor before my child gets the nasal flu vaccine?

• Your child has any allergies.
• Your child has a chronic health problem, such as diabetes or a heart, lung, kidney, or liver disease.
• Your child receives dialysis.
• Your child developed Guillain-Barré syndrome within 6 weeks of getting a flu vaccine. He or she may not be able to get any flu vaccine unless the provider feels the benefits outweigh the risks.
