Usage of Flumist

FluMist Quadrivalent is a nasal spray flu vaccine used to prevent infection against four strains of the influenza virus. FluMist works by exposing you to a small dose of the weakened influenza virus, which helps your body to develop immunity to the disease. FluMist Quadrivalent can be used for people from 2 to 49 years of age.

FluMist Quadrivalent 2023-2024 Formula contains two influenza A subtype viruses (A/H1N1 strain, A/H3N2 strain) and two influenza B strains (B/Yamagata/16/88 lineages, B/Victoria/2/87 lineages). The vaccine is redeveloped each year to contain specific strains of activated (live) flu virus that are recommended by public health officials for that year.

Influenza (commonly known as "the flu") is a serious disease caused by a virus. Influenza virus can spread from one person to another through small droplets of saliva that are expelled into the air when an infected person coughs or sneezes. The virus can also be passed through contact with objects the infected person has touched, such as a door handle or other surfaces.
