The U.S. Food and Drug Administration (FDA) recently approved a nasal spray flu vaccine, called FluMist, for people ages 2 to 49 that can be ordered from an online pharmacy and administered at home. Doctors and public health experts are hopeful the at-home option, which should be available for the 2025–26 flu season, will help boost declining vaccination rates and protect more Americans from the common but sometimes deadly illness. Less than half of U.S. adults (45 percent) got a flu shot last year, and only 38 percent plan to get a flu vaccine this year, a new report from the National Foundation for Infectious Diseases finds.
