It was recently approved by the FDA.
FluMist, a nasal spray flu vaccine, has recently been approved by the FDA for at-home use starting in the fall of 2025, offering an alternative to traditional flu shots for families. Although currently administered by healthcare professionals, FluMist will soon be available for self-administration, allowing people greater convenience in managing their flu protection.
Designed to combat influenza with a live, weakened virus, FluMist aims to prepare the respiratory system to respond to flu germs more effectively. Approved for healthy children ages 2 and older, as well as adults up to 49, it is a suitable option for those who are needle-averse. Dr. Pedro Piedra from Baylor College of Medicine explains that FluMist stimulates a strong immune response in the nasal passages, providing defense at the primary point of viral entry. However, it’s not recommended for people with compromised immune systems or specific respiratory conditions due to the risks associated with a live vaccine.
Though FluMist is generally as effective as a standard flu shot within its age range, it carries potential side effects, especially for certain individuals. For instance, children under age 5 with a history of wheezing, as well as those with significant lung conditions, may experience respiratory side effects, including wheezing. For these individuals, Dr. Piedra recommends consulting with a doctor to explore other flu vaccine options that avoid potential respiratory impacts.
For those choosing FluMist, precautions are advised to maximize its effectiveness. Avoiding antiviral medications for two weeks before and after receiving the vaccine is recommended since antivirals could interfere with the weakened virus in the spray. Additionally, children should avoid aspirin immediately after vaccination to prevent Reye’s syndrome, a rare but serious condition affecting the liver and brain. Individuals with severe allergies to the spray’s ingredients should also avoid FluMist.
Once FluMist becomes available for at-home use, families will have the freedom to administer it according to their schedules. However, Dr. Piedra urges caution if there are immunocompromised individuals in the household and suggests consulting with healthcare providers if there are any concerns about whether FluMist is the right choice. This flexibility will likely make flu prevention more accessible, but informed use is essential for safe and effective results.
