Precautions

Influenza virus vaccine, H1N1, live is contraindicated in individuals with a history of hypersensitivity, especially anaphylactic reactions, to eggs, egg proteins, gentamicin, gelatin, or arginine or with life-threatening reactions to previous influenza vaccinations.

Influenza virus vaccine, H1N1, live is contraindicated in children and adolescents (2 to 17 years of age) receiving aspirin therapy or aspirin-containing therapy, because of the association of Reye's syndrome with aspirin and wild-type influenza infection.

Influenza virus vaccine, H1N1, live should not be administered to any individuals with asthma or children less than 5 years of age with recurrent wheezing because of the potential for increased risk of wheezing post vaccination unless the potential benefit outweighs the potential risk.

Do not administer influenza virus vaccine, H1N1, live to individuals with severe asthma or active wheezing.

If Guillain-Barré syndrome has occurred within 6 weeks of any prior influenza vaccination, the decision to give influenza virus vaccine, H1N1, live should be based on careful consideration of the potential benefits and potential risks.

Administration of influenza virus vaccine, H1N1, live to immunocompromised persons should be based on careful consideration of potential benefits and risks.

Appropriate medical treatment and supervision must be available to manage possible anaphylactic reactions following administration of the vaccine.

Other Comments

Administer vaccine prior to exposure to influenza. It is important to note that influenza seasons vary in their timing and duration from year to year. In general, vaccination should begin soon after the vaccine becomes available and if possible, prior to October. However, vaccination should continue throughout the influenza season as long as vaccine is available. For children ages 2 to 8 years who have never received influenza vaccine, vaccinate in October or earlier since a second dose will need to be given one month after the initial dose.
