The U.S. Food and Drug Administration (FDA) has approved the at-home use of nasal spray flu vaccine which can be self-administered without the help of a healthcare provider.
FluMist nasal spray manufactured by AstraZeneca is now approved for home use against influenza infection caused by subtypes A and B from ages 2 through 49. It was initially approved for prescription-based use in healthcare settings from 5 to 49 years of age in 2003. Later in 2007, the FDA approval included use in children from 2 through 5 years of age.
