The 2009 H1N1 flu vaccines that the FDA has approved, will be manufactured in several formulations. Some will come in multi-dose vials and will contain thimerosal as a preservative to prevent potential contamination after the vial is opened. Some vaccine manufacturers will be producing 2009 H1N1 flu vaccine in single-dose units, which will not require the use of thimerosal as a preservative. In addition, the live-attenuated version of the vaccine, which is administered through the nose, is produced in single-units and will not contain thimerosal.
