The U.S. Public Health Services and the American Academy of Pediatrics called for the removal of Thimerosal from U.S. vaccines licensed since 2001 in 1999 but people are still being exposed to mercury through flu shots, where most doses still are still preserved with Thimerosal. These vaccines are routinely recommended for children and pregnant women. (http://www.prnewswire.com/news-rele…)
Mercury is used as a preservative in multi-dose vials of vaccines. Preservatives are used in multi-dose vials because a syringe needle inserted multiple times can introduce bacteria and fungi each time. Mercury can be avoided by using single-dose vials, which do not require a preservative, since they are used only once. There is also a less toxic alternative to mercury that can be used for multi-dose vials called 2-phenoxyethanol.
