Do not receive this vaccine if you have ever had an allergic reaction to a flu vaccine, or if you have:
- a history of Guillain-Barré syndrome (especially if you had it within 6 weeks after having a flu vaccine);
- a weak immune system caused by disease (such as cancer, HIV, or AIDS), or by taking certain medicines such as steroids;
- if someone in your household has a weak immune system;
- if you are under 18 years old and have recently taken aspirin or other similar medicines such as Disalcid, Doan's Pills, Dolobid, Salflex, Tricosal, and others; or
- if you are allergic to chicken or egg products.
Before receiving nasal influenza virus vaccine, tell your doctor if you are allergic to any drugs, or:
- asthma or other lung disorder;
- a history of seizures;
- a neurologic disorder or disease affecting the brain (or if this was a reaction to a previous vaccine);
- a weak immune system caused by disease, bone marrow transplant, or by using certain medicines or receiving cancer treatments; or
- if you have used a flu medication such as oseltamivir (Tamiflu) or zanamivir (Relenza) within the past 48 hours.
You can still receive a vaccine if you have a cold or fever. In the case of a more severe illness with a fever or any type of infection, wait until you get better before receiving this vaccine.
Vaccines may be harmful to an unborn baby and generally should not be given to a pregnant woman. However, not vaccinating the mother could be more harmful to the baby if the mother becomes infected with a disease that this vaccine could prevent. Your doctor will decide whether you should receive this vaccine, especially if you have a high risk of infection with influenza.
It is not known whether nasal influenza virus vaccine passes into breast milk or if it could harm a nursing baby. Do not use this medication without telling your doctor if you are breast-feeding a baby.
This vaccine should not be given to anyone younger than 2 or older than 49 years of age.
How is this vaccine given (FluMist)?
This vaccine is given as a nasal spray into each nostril. Your doctor, nurse, or other healthcare provider will give you this vaccine.
You should receive a flu vaccine every year. Your immunity will gradually decrease over the 12 months after you receive the influenza virus vaccine. Children receiving this vaccine may need a repeat dose two months after receiving the first vaccine.
The influenza virus vaccine is usually given in October or November. Some people may need to have their vaccines earlier or later. Follow your doctor's instructions.
Your doctor may recommend treating fever and pain with an aspirin-free pain reliever such as acetaminophen (Tylenol) or ibuprofen (Motrin, Advil, and others) when the vaccine is given and for the next 24 hours. Follow the label directions or your doctor's instructions about how much of this medicine to take.
It is especially important to prevent fever from occurring if you have a seizure disorder such as epilepsy.
