• FluMist is the first vaccine to prevent influenza that can be administered at home
• Common side effects include fever in young children and sore throat in adults

The US has approved a nasal spray vaccine to fight against influenza (flu) diseases caused by influenza virus subtypes A and B, for people aged 2 to 49.

The nasal spray, called FluMist, doesn't require a doctor and can be used for self-administration or by a caregiver. It is sprayed into the nose and has been used safely and effectively for many years.

FluMist is the first vaccine to prevent influenza, more commonly known as the flu, that does not need to be administered by a health care provider.

"Today’s approval of the first influenza vaccine for self- or caregiver-administration provides a new option for receiving a safe and effective seasonal influenza vaccine potentially with greater convenience, flexibility and accessibility for individuals and families," said Peter Marks, director of the FDA's Center for Biologics Evaluation and Research.

The flu is a common contagious respiratory illness caused by influenza viruses, typically circulating during the monsoon and winter seasons. Symptoms, such as body aches, fever, cough, and sore throat, often appear suddenly and can range from mild to severe.

The flu can lead to serious complications, especially in high-risk groups like the elderly, young children, and those with chronic health conditions.

Vaccines are available every flu season to prevent the illness. It is being manufactured by AstraZeneca's MedImmune, LLC.

FluMist, a nasal spray vaccine with weakened live influenza virus strains, requires a prescription and can be administered by a healthcare provider or by a caregiver aged 18 or older.

Common side effects include fever in young children, nasal congestion in individuals aged 2 to 49, and sore throat in adults.

For those opting for self-administration, FluMist can be ordered through an online pharmacy after completing a screening assessment.

The vaccine can then be given to the designated household member(s) at their convenience. Caregivers must administer FluMist to individuals aged 2 to 17, as they are not allowed to self-administer.

The vaccine package includes detailed instructions for storage, use, and disposal to ensure proper administration.

"It was initially approved by the FDA in 2003 for use in individuals 5 through 49 years of age, and in 2007, the FDA approved the use of FluMist to include children 2 through 5 years of age," the FDA report said.
