How to avoid Thimerosal

Flu vaccines in multi-dose vials contain thimerosal. Most single-dose vials and pre-filled syringes of flu shot and the nasal spray flu vaccine do not contain a preservative because they are intended to be used once.


FLUARIX QUADRIVALENT is formulated without preservatives. FLUARIXQUADRIVALENT does not contain thimerosal.
