AstraZeneca’s FluMist Home program officially launches today, sending nasal flu vaccines straight to people’s homes. FluMist is a flu vaccine that’s sprayed up your nose. It’s been FDA-approved since 2003, and studies show it works about as well as the traditional flu shot at preventing infections and reducing the risk of serious illness.

For the first time, many people in the United States who want to protect themselves against the flu this respiratory virus season can order a vaccine to give themselves at home.
