The U.S. Food and Drug Administration said on Friday it has approved AstraZeneca's nasal spray flu vaccine for self-administration, making it the first of its kind. FluMist is the first vaccine to prevent influenza that does not need to be administered by a healthcare provider,

FluMist is the only flu vaccine administered by nasal spray, not injection. It is licensed for individuals between the ages of 2 and 49. This FDA approval makes it the only flu vaccine in the United States that can be administered at home and that does not need to be administered by a health care professional.
