IMPACT OF EGG ADAPTATION ON FLU-RELATED HOSPITALIZATIONS14
US Influenza-Related Hospitalizations
In 3 recent flu seasons, vaccine strains
matched circulating strains
In 7 other recent seasons, vaccine strains
did not match circulating strains
Nearly half of those were caused by
egg adaptation3-13
3 of the 4 highest rates of hospitalization were in egg-adapted seasons3-14

INDICATION AND IMPORTANT SAFETY INFORMATION

IMPORTANT SAFETY INFORMATION

CONTRAINDICATIONS

Do not administer FLUAD QUADRIVALENT or AFLURIA QUADRIVALENT to anyone with a history of severe allergic reaction (e.g. anaphylaxis) to any component of the vaccine, including egg protein, or to a previous influenza vaccine.

Do not administer FLUCELVAX QUADRIVALENT to anyone with a history of severe allergic reactions (e.g. anaphylaxis) to any component of the vaccine.

WARNINGS AND PRECAUTIONS

If Guillain-Barré syndrome (GBS) has occurred within 6 weeks of receipt of prior influenza vaccine, the decision to give FLUAD QUADRIVALENT, FLUCELVAX QUADRIVALENT, or AFLURIA QUADRIVALENT should be based on careful consideration of the potential benefits and risks.

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

Syncope (fainting) may occur in association with administration of injectable vaccines. Syncope can be accompanied by transient neurological signs such as visual disturbance, paresthesia, and tonic-clonic limb movements. Ensure procedures are in place to avoid falling injury and to restore cerebral perfusion following syncope by maintaining a supine or Trendelenburg position.

The immune response to FLUAD QUADRIVALENT, FLUCELVAX QUADRIVALENT, or AFLURIA QUADRIVALENT in immunocompromised persons, including individuals receiving immunosuppressive therapy, may be lower than in immunocompetent individuals.

Vaccination with FLUAD QUADRIVALENT, FLUCELVAX QUADRIVALENT, or AFLURIA QUADRIVALENT may not protect all vaccine recipients against influenza disease.

AFLURIA (trivalent formulation) administered by PharmaJet Stratis Needle-Free Injection System:

The safety experience with AFLURIA (trivalent formulation) is relevant to AFLURIA QUADRIVALENT because both vaccines are manufactured using the same process and have overlapping compositions.
