FluMist by MedImmune


Updated October 06, 2009

What is FluMist by MedImmune?:

FluMist by MedImmune is an alternative method of administering a flu vaccination. Instead of a shot it is given as a liquid which is sprayed into the nostrils. The medicine is then absorbed by the tissue lining inside of the nose. Unlike a flu shot which contains a killed virus, the FluMist contains an attenuated (weakened) virus. Because of this FluMist is not recommended for all patients.

Advantages Over Traditional Vaccination:

Advantages of FluMist include comfort for the patient -- particularly for children or adults who don't do well with needles. Because of this advantage, the FluMist may result in a higher percentage of the overall population becoming vaccinated, and a subsequent decrease in the overall number of influenza cases.

In a study sponsored by MedImmune the FluMist was more effective in children aged 6 months to 17 years than traditional vaccination.

Who Can Take FluMist?:

Healthy individuals between the ages of 2 and 49 years old.

  • be given to the following groups:
  • Immunosuppressed patients

  • Persons with a history of Guillain-Barre syndrome
  • Pregnant women
  • People with egg allergy

What Are the Side Effects of FluMist?:

The most common side effects include runny nose, nasal congestion, fever, and sore throat.
