Mercury in the Flu Shot

While concerned parents have lobbied successfully to remove mercury (thimerosal) from routine childhood vaccinations, no one is mentioning that the widely-advised flu shot still contains thimerosal.

Mercury poisoning has been linked to harm in the nervous system, heart, lungs, kidneys, and immune system. It can cause mental dysfunction in growing children and dementia and malaise in adults. Some believe thimerosal in vaccines is linked to autism. No amount of mercury is considered safe.

According to the Centers for Disease Control (CDC), thimerosal is not the only non-medicinal additive in our vaccines. Vaccines may contain any or all of the following:

Type of Ingredient	Examples	Purpose
Preservatives	Thimerosal (only in multi-dose vials of flu vaccine)	To prevent contamination
Adjuvants	Aluminum salts	To help stimulate the body’s response to the antigens
Stabilizers	Sugars, gelatin	To keep the vaccine potent during transportation and storage
Residual cell culture materials	Egg protein	To grow enough of the virus or bacteria to make the vaccine
Residual inactivating ingredients	Formaldehyde	To kill viruses or inactivate toxins during the manufacturing process
Residual antibiotics	Penicillin, sulfa drugs	To prevent contamination by bacteria during the vaccine manufacturing process

You can request a thimerosal-free version of the flu vaccine; it will come in a single-use rather than a multi-use vial.

Here is the CDC’s table of what exactly is in each version of the influenza vaccine, so that you can check to see if there are any ingredients you might already know you’re sensitive to, like polysorbate 80, a chemical surfectant an emulsifier that we test for with the MRT because it can trigger reactions in many people, before agreeing to be injected.
