A flu vaccine teaches your immune system to recognize that virus as a threat..
Do vaccines have Formaldehyde?
Formaldehyde is diluted during the vaccine manufacturing process, but residual quantities of formaldehyde may be found in some current vaccines. The amount of formaldehyde present in some vaccines is so small compared to the concentration that occurs naturally in the body that it does not pose a safety concern.
Can you get a flu shot without thimerosal?
The preservative-free flu vaccine is a type of flu vaccine that does not contain thimerosal. The mercury-based compound is added to some vaccines to prevent the growth of bacteria, fungus, or other microorganisms that might contaminate a vial when a needle is inserted.
Is mercury still used in vaccines?
Manufacturing of childhood vaccines with thimerosal as a preservative ceases. All childhood vaccines with thimerosal as a preservative have passed their expiration date and are no longer available in the U.S. The amount of mercury in vaccines recommended for children is close to zero.
How much mercury is in a flu shot?

Is the mercury in flu shots harmful?
Flu vaccines in multi-dose vials contain small traces of formaldehyde and thimerosal, a mercury-containing compound, but these occur and are processed naturally in the body and pose no credible safety concerns.
Is thimerosal a disinfectant?
Thimerosal is an alkylmercury compound (approximately 49% mercury by weight) used as an antiseptic and antifungal agent. It has a role as a disinfectant, an antifungal drug, an antiseptic drug and a drug allergen.
Do flu shots work?
What do recent vaccine effectiveness studies show? Recent studies show flu vaccine can reduce the risk of flu illness by between 40% and 60% among the overall population during seasons when most circulating flu viruses are well matched to the flu vaccine viruses.
What is really in a flu shot?
This water-soluble molecule crosslinks proteins in the virus so it can’t cause illness. Your shot can include up to 100 micrograms of formaldehyde, but your blood naturally contains 13,000 mcg—that extra 0.8 percent barely registers.

Is thimerosal toxic?
About Thimerosal Methylmercury is the type of mercury found in certain kinds of fish. At high exposure levels methylmercury can be toxic to people.
How effective is the 2020 flu shot?
CDC’s influenza vaccination coverage reports show that overall flu vaccination coverage (among people 6 months and older) during 2019-2020 increased from the previous season to nearly 52%.
Does the flu shot have formaldehyde in it?
Like many vaccines, a flu shot does contain the virus that it is preventing. That’s where formaldehyde comes in, to deactivate the virus and prevent the toxins from causing illness. In large doses, formaldehyde is toxic and deadly.
