FDA approves nasal spray influenza vaccine for self- or caregiver-administration

Sept. 23, 2024
First influenza vaccine that does not need to be administered by a healthcare provider.

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.

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 healthcare provider in a healthcare 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. Those who choose this option will complete a screening and eligibility assessment when they order FluMist. The third-party pharmacy determines eligibility based on the completed screening and, if it is determined that the intended vaccine recipient is eligible, the pharmacy writes the prescription and ships the vaccine to the address provided by the individual who placed the order. The vaccine can then be administered to the prescribed household member(s) at their convenience. A caregiver should administer FluMist to individuals 2 through 17 years of age, as individuals in this age group should not self-administer the vaccine.

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.

Vaccine recipients and caregivers who administer FluMist will be sent the vaccine, the Prescribing Information, Information for Patients and their Caregivers and Instructions for Use. The Instructions for Use provides detailed instructions for storage, administration and disposal of FluMist.

The FDA granted this approval of FluMist (Influenza Vaccine Live, Intranasal) to MedImmune LLC.
