What purpose does mercury serve in vaccines?

Mercury is a metal found naturally in the environment. Why is thimerosal used in some vaccines? Because it prevents the growth of dangerous microbes, thimerosal is used as a preservative in multi-dose vials of flu vaccines, and in two other childhood vaccines, it is used in the manufacturing process.

What are the side effects of thimerosal?

Are there side effects from thimerosal in vaccines? Most people don’t have any side effects from thimerosal, but some people will have mild side effects like redness and swelling at the place where the shot was given, which will only last 1 to 2 days. It’s very unlikely you will have an allergic reaction to thimerosal.

Does the Tdap vaccine contain mercury?

The vaccine contains a trace amount of thimerosal (not as a preservative) from the manufacturing process [≤0.3 micrograms (μg) mercury/dose].

How long does thimerosal stay in the body?

In the thimerosal group, the half-life of total mercury in blood was 6.9 days, compared to 19.1 days for the methylmercury group.

Does the flu vaccine contain mercury?

Do vaccines contain mercury? Answer: Almost all childhood vaccines DO NOT contain mercury. However, some influenza (flu) vaccines that have more than one dose in the vial (multi-dose vials) contain thimerosal, which is a mercury-based preservative.

What does the Covid vaccine contain?

mRNA – Also known as messenger ribonucleic acid, mRNA is the only active ingredient in the vaccine. The mRNA molecules contain the genetic material that provide instructions for our body on how to make a viral protein that triggers an immune response within our bodies.

Do flu shots have mercury in it?

Most flu vaccines are given from single-dose vials and do not contain mercury. Thimerosal is different than the mercury that causes mercury poisoning, and our bodies process it easily.

Can you get a flu shot without thimerosal?

Flu vaccine that does not contain thimerosal is available in single-dose vials or single-dose syringes. One formulation of single-dose inactivated flu vaccine, Fluvirin, contains trace amounts of thimerosal.

What does the Pfizer-BioNTech Covid-19 vaccine contain?

The Pfizer-BioNTech COVID-19 vaccine also contains a harmless piece of messenger RNA (mRNA). The COVID-19 mRNA teaches cells in the body how to create an immune response to the virus that causes COVID-19. This response helps protect you from getting sick with COVID-19 in the future.

Does the 2021 flu vaccine contain thimerosal?

For the 2021-2022 season, only multidose vial formulations of influenza vaccines will contain thimerosal. Approximately 87% of projected vaccine supply produced for the 2021-2022 flu season will be thimerosal-free or thimerosal-reduced (i.e., preservative-free).

How does mercury affect the brain?

Many studies show that high exposure to mercury induces changes in the central nervous system, potentially resulting in irritability, fatigue, behavioral changes, tremors, headaches, hearing and cognitive loss, dysarthria, incoordination, hallucinations, and death.

Can I get a flu shot without mercury?

In this regard, all vaccines routinely recommended for children 6 years of age or younger and marketed in the U.S. contain no thimerosal or only trace amounts (1 microgram or less mercury per dose), with the exception of inactivated influenza vaccine, which was first recommended by the Advisory Committee on …

Is mercury toxic to humans?

All Mercury is Toxic Depending on the type and amount, exposures to mercury can damage the nervous system, kidneys, liver and immune system. Breathing mercury vapors can harm the nervous system, lungs and kidneys. Mercury vapors can pass easily from the lungs to the bloodstream.

How is thimerosal different from mercury?

Thimerosal contains ethylmercury, which is cleared from the human body more quickly than methylmercury, and is therefore less likely to cause any harm.
