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.

FluMist Home is available only online. People ordering the nasal spray will need to complete a medical screening questionnaire at FluMist.com that is reviewed by a health care professional, according to the drugmaker. FluMist Home’s online pharmacy will then collect the insurance information and bill the health plan directly.
