Influenza virus vaccine live - nasal

This medication is a vaccine against influenza (flu) virus. It is also called the seasonal flu vaccine. The vaccine works by helping the body produce immunity (protection) that will prevent you from getting the flu or lessen the seriousness of the infection. As with any vaccine, it may not fully protect everyone who receives it. Since different types of flu viruses cause infection every flu season, usually a new vaccine is produced and given for each flu season.
This form of the vaccine is given through the nose and is recommended for healthy children and adults. It is not recommended for people with a history of severe asthma or active wheezing. Consult your health care professional for more details.
Read all vaccine information available from your health care professional before receiving the vaccine. If you have any questions, ask your health care professional.
If this vaccine is the first flu vaccination of a child aged 2 through 8 years, the child should receive a second dose (usually at least 1 month after the first dose). If a child in this age group has received this vaccine in a previous flu season, only one dose is given. Patients aged 9 years and older (including adults) should receive only one dose for each flu season.
To receive this vaccine, sit or stand upright with your head tilted back. A health care professional will spray the medication into each nostril, one at a time.
Cough, runny nose, sneezing, sore throat, fever, headache, chills, or tiredness may occur. If any of these effects persist or worsen, tell your health care professional promptly.
Remember that your health care professional has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.
