What Is The FluMist Flu Vaccine?



Flu Mist is a nasal spray mist vaccine. FluMist contains three live viral flu strains, which have been weakened. The flu shot, by contrast, is made using a killed virus. After the weakened influenza viruses enter the nose, the body develops an immune response that helps prevent the flu for the entire season. FluMist is now approved for healthy children 2-17 years and healthy adults 18-49 years of age.

Who Should Not Receive FluMist Flu Vaccine?

People who have a weak immune system or have chronic diseases like asthma or diabetes or heart disease should not get FluMist. And like most all medication, you should check with your healthcare provider before receiving any flu vaccines. Per the approved packaging insert, the following people should not receive the intranasal influenza vaccine:

  • Adults 50 years of age or older, or children younger than 5 years old.
  • Pregnant women should not receive FluMist.
  • The safety of FluMist in people with asthma or other reactive airway diseases has not been established, and therefore, is not recommended for use in patients with a history of reactive airway problems.
  • Additionally, FluMist should not be given to people with chronic underlying medical conditions that may predispose them to severe flu infections. For these people, the injected vaccine is indicated.
  • Individuals with egg allergies should not receive this or any other flu vaccine without first consulting their physicians.
  • People who have health problems associated with heart disease, kidney disease, lung disease, or metabolic diseases such as diabetes, anemia and other blood disorders should not receive FluMist.
  • Because Reye syndrome in children has been associated with administration of aspirin during influenza virus infections, FluMist is not recommended in children and adolescents 5-17 years of age if they are receiving aspirin or aspirin-containing therapy.
  • Anyone with a history of Guillain Barré Syndrome (GBS) should not receive FluMist.
  • FluMist recipients should avoid close contact (e.g., within the same household) with anyone with a weakened immune system for at least 21 days after receiving the vaccine.
  • FluMist should not be given for any reason to people with immune suppression. This includes people with primary immune deficiency diseases, as well as people with immune deficiencies related to HIV infection, cancer, or other conditions, and people who are being treated with drugs that cause immunosuppression.

Can FluMist Give You The Flu?

The vaccination with FluMist involves the administration of attenuated (weakened) viruses into the nose by a  nasal sprayer. Some recipients will experience low-grade fever, upper respiratory symptoms and muscle aches, but these are generally milder than when a person has a symptomatic influenza infection. Although the vaccine viruses are attenuated in healthy people, there is little information regarding the use of FluMist in people with weakened or compromised immune systems. People with weakened or compromised immune systems should not receive FluMist.


Flumist Studies and Clinical Trials

The University of Maryland was one of the 10 centers involved in a FluMist clinical trials from 1996 to 1998. The vaccine study enrolled 1,602 healthy children ranging in age from 15 months to 6 years. At the University of Maryland Medical Center, 110 children took part in the study. Two-thirds of the children received the nasal flu vaccine and one third received a placebo.  The study showed that nasal spray flu vaccine effectively prevents the flu in children.

"This vaccine is a major breakthrough in the effort to immunize children against flu without the fear and pain of a shot," said King, who is a co-author of an article about the study. "Children who received the vaccine had 93 percent fewer cases of influenza than the children who received a placebo."
