Floggi’s posts need more underlined/italicized words. Not convincing enough.
Just because the vaccine doesn’t contain thimerosal itself doesn’t mean you aren’t getting any from the vial. The multi-dose vials do contain thimerosal. Straight from the CDC’s website:
Do the 2013-2014 seasonal flu vaccines contain thimerosal?
The Food and Drug Administration (FDA) has approved several formulations of the seasonal flu vaccine, including multi-dose vials and single-dose units. (See Table of Approved Influenza Vaccines for the U.S. 2013–2014 Season.) Since seasonal influenza vaccine is produced in large quantities for annual immunization campaigns, some of the vaccine is produced in multi-dose vials, and contains thimerosal to safeguard against possible contamination of the vial once it is opened.
The single-dose units are made without thimerosal as a preservative because they are intended to be opened and used only once. Additionally, the live-attenuated version of the vaccine (the nasal spray vaccine), is produced in single-dose units and does not contain thimerosal.
