FluMist Now Approved for Self- or Caregiver-Administration by FDA

On Sept. 20, the U.S. Food and Drug Administration approved FluMist for self- or caregiver-administration. FluMist is approved for the prevention of influenza disease caused by influenza virus subtypes A and B in individuals 2 through 49 years of age. FluMist is sprayed into the nose and has been used safely and effectively for many years. It was initially approved by the FDA in 2003 for use in individuals 5 through 49 years of age, and in 2007, the FDA approved the use of FluMist to include children 2 through 5 years of age. It is the first vaccine to prevent influenza, more commonly known as the flu, that does not need to be administered by a healthcare provider.

The flu is a common and contagious respiratory disease that is caused by influenza viruses that typically circulate during the fall and winter in the U.S. It can cause mild to severe illness with a range of symptoms that usually appear suddenly, such as body aches, fever, coughing, sore throat, tiredness and a stuffy or runny nose. Flu can be life-threatening and cause serious complications that can lead to hospitalization or death, particularly in high-risk groups such as the elderly, young children and people with certain chronic medical conditions. Each flu season is different and the health impacts can be substantial and vary widely from season to season, with some flu seasons being worse than others. According to the U.S. Centers for Disease Control and Prevention, flu has resulted in about 9.3 million to 41 million illnesses, 100,000 to 710,000 hospitalizations and 4,900 to 51,000 deaths annually between 2010 and 2023. Numerous FDA-approved vaccines are available each flu season to prevent influenza.

FluMist contains a weakened form of live influenza virus strains and is sprayed in the nose. A prescription is still required to receive FluMist. There are now two approved options for receiving FluMist. The vaccine may be administered by a health care provider in a health care setting (including a pharmacy) or it may be administered by the vaccine recipient or a caregiver who is 18 years of age or older.

The most commonly reported side effects of FluMist are fever over 100°F in children 2 through 6 years of age, runny nose and nasal congestion in individuals 2 through 49 years of age and a sore throat in adults 18 through 49 years of age.

For those interested in self- or caregiver-administration, the vaccine manufacturer plans to make the vaccine available through a third-party online pharmacy.

A study was conducted with vaccine recipients and caregivers to evaluate whether the instructions for use were appropriately designed so that recipients and caregivers could safely and effectively use the vaccine.
