Influenza (flu) vaccine

Influenza (flu) is a lung (respiratory) infection that can cause serious complications, especially in young children. Complications can include pneumonia and ear infections. And it can cause asthma flare-ups.

The flu vaccine can lower your child's risk of the flu and its severity. And it can lower your child's risk of needing to stay in the hospital due to serious illness from the flu. The flu vaccine causes your child's body to make antibodies to protect against the flu.

The CDC recommends a flu vaccine every year for everyone age 6 months or older. The flu shot can cause some side effects and has some precautions. If your child has an egg allergy, your child can still get a flu vaccine. Each year's flu vaccine provides protection from the flu viruses research expects to be the most common during the year's flu season. The vaccine is available as a shot, or injection, and as a nasal spray. Children under 2 shouldn't get the nasal spray.
