What is FluMist Quadrivalent?

Turn your nose into a flu-fighting force with needle-free FluMist Quadrivalent

Needle-free FluMist Quadrivalent is a nasal-spray flu vaccine that helps protect eligible kids and adults, ages 2 through 49, from the flu.

  • Works in the nose, where the flu typically starts
  • Helps protect against the 4 flu strains included in the vaccine
    • Historically, trivalent FluMist® (Influenza Vaccine Live, Intranasal) helped protect against 3 strains contained in the vaccine
  • Delivers immunity in multiple ways—in the nose, in the cells, and in the bloodstream

There are 3 types of flu viruses: A, B, and C. The A and B viruses cause seasonal influenza almost every winter in the United States. The A and B viruses can be broken down into different strains.

The trivalent formulation of FluMist helped protect against 2 A strains and one B strain included in the vaccine. Quadrivalent flu vaccines, such as FluMist Quadrivalent, help protect against 2 A strains and 2 B strains contained in the vaccine.
