FLUMIST QUADRIVALENT starts working where the flu typically enters the body—the nose

The flu mainly spreads by tiny droplets made when people with flu cough, sneeze, or talk.

  • These droplets can land in the mouths or noses of people nearby
  • People with flu can spread it to others about 6 feet away

The flu typically enters your body through your nose, so it's important to help fight the flu virus there

  • One spray of FLUMIST QUADRIVALENT in each nostril can help protect eligible children and adults ages 2-49
    • People 9 years of age and older need one dose of FLUMIST QUADRIVALENT each year
    • Children 2 through 8 years old may need 2 doses of FLUMIST QUADRIVALENT, depending on their history of previous influenza vaccination. Your healthcare provider will decide if your child needs to come back for a second dose

It is engineered to PROTECT—NOT INFECT

Similar to other live vaccines, like the chicken pox vaccine, FLUMIST QUADRIVALENT contains a weakened live virus

  • The weakened live virus is designed not to cause the flu, but to help protect you from the flu

FLUMIST QUADRIVALENT triggers an immune response in the nose—the place where you usually catch the flu

  • It then triggers your immune system to build defenses (called antibodies) mainly in the nose where the virus enters the body
  • This is how FLUMIST QUADRIVALENT can help prevent you from getting the flu


  • Administered by a healthcare professional
  • 1 spray in each nostril
  • You don't need to sniff. You can breathe normally while you get FLUMIST QUADRIVALENT
  • It's okay if you sneeze, blow your nose, feel dripping down your nose or throat, or swallow after receiving FLUMIST QUADRIVALENT. You still get enough FLUMIST QUADRIVALENT to help protect you against the flu
