FLUCELVAX QUADRIVALENT is made using cell culture technology, which does not rely on eggs for manufacturing and has the potential to rapidly increase production of flu shots in times of need.1,2 It's also antibiotic, preservative, and latex free, and it helps protect against 4 strains of the flu in people aged 4 years and older.2 This flu season, consider a flu shot that’s on the cutting edge of flu protection.

Important Safety Information
  • Do not administer FLUCELVAX QUADRIVALENT to anyone with a history of severe allergic reaction (e.g. anaphylaxis) to any component of the vaccine.
Warnings & Precautions
  • Guillain-Barré Syndrome (GBS): If GBS has occurred within 6 weeks of receipt of a prior influenza vaccine, the decision to give FLUCELVAX QUADRIVALENT should be based on careful consideration of the potential benefits and risks.
