A PURE Choice

You have a choice in flu vaccines. Flublok is a pure choice, not only for people with allergies, but for everyone 18 and older.

Unlike other flu vaccines, Flublok does not use the influenza virus or eggs anywhere in its production process. By using modern technology, Flublok is highly pure and the only flu vaccine manufactured without any of the following:

  • Eggs
  • Preservatives, such as thimerosal
  • Live or inactivated influenza virus
  • Latex
  • Formaldehyde
  • Gelatin
  • Antibiotics
  • Gluten

Flublok contains only the protective ingredients needed (called the hemagglutinin protein or HA) and does not require growing the influenza virus. This makes Flublok ideal for people who have allergies or concerns with any of the ingredients listed above or simply want a pure, effective product.
