Do allergy shots have mercury in them?

Another example is that clinicians should offer relevant comparisons such as: allergen vaccines do not contain mercury metal but often have harmless aluminium salts as adjuvants.

Are allergy shots harmful?

You may develop sneezing, nasal congestion or hives. More-severe reactions may include throat swelling, wheezing or chest tightness. Anaphylaxis is a rare life-threatening reaction to allergy shots. It can cause low blood pressure and trouble breathing.

How much mercury is in vaccines?

A vaccine containing 0.01% thimerosal as a preservative contains 50 micrograms of thimerosal per 0.5 mL dose or approximately 25 micrograms of mercury per 0.5 mL dose. For comparison, this is roughly the same amount of elemental mercury contained in a 3 ounce can of tuna fish.

Is there mercury in vaccines today?

This mercury-containing ingredient has been used as a preservative in vaccines since the 1930s. Today, it is only found in vaccines for influenza. Preservatives are necessary for preventing dangerous bacterial or fungal contamination, but thimerosal has since become a major source of vaccine safety concerns.

Can you be allergic to thimerosal?

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.

Do allergy shots affect your immune system?

Allergy shots, also known as allergen immunotherapy, cause the body to stop generating symptoms after exposure to certain allergens. Tiny amounts of the offending substance are injected under the skin with each shot. The shots stimulate the immune system just a little each time.

Do allergy shots work for dust mites?

Many people with a dust mite allergy do not get complete relief from medicines. This means they may consider immunotherapy (allergy shots). Immunotherapy is a long-term treatment that can help prevent or reduce the severity of allergic reactions.

Does flu shot contain mercury?

WHAT THE EVIDENCE SAYS: Currently available flu vaccines are aluminum-free and over 80% of flu vaccines today contain no mercury at all. Some flu vaccines contain a tiny amount of formaldehyde that is less than 1% of the amount naturally found in people and is safely cleared from the body.

What is the purpose of mercury 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.

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.

Does fluzone contain mercury?

The 5 mL multi-dose vial presentation contains thimerosal, a mercury derivative, added as a preservative. Each 0.5 mL dose from the multi-dose vial contains 25 mcg mercury.

What kind of mercury is in vaccines?

Thimerosal is a mercury-based preservative that has been used for decades in the United States in multi-dose vials (vials containing more than one dose) of medicines and vaccines.

Why mercury is bad for you?

The inhalation of mercury vapour can produce harmful effects on the nervous, digestive and immune systems, lungs and kidneys, and may be fatal. The inorganic salts of mercury are corrosive to the skin, eyes and gastrointestinal tract, and may induce kidney toxicity if ingested.

What vaccines still have thimerosal?

The only vaccine that still includes thimerosal as a preservative is the multi-dose inactivated influenza vaccine. There are other formulations of flu vaccine that do not include thimerosal.

What is thimerosal allergy?

Localised allergic contact dermatitis (itchy red patches) may occur in sensitive individuals. This may include redness and swelling at the injection site when injectable thiomersal-containing products are used. Most reactions are usually mild and resolve spontaneously after a few days.

Does thimerosal accumulate in the body?

The half-life of ethyl mercury is short (less than one week) compared to methyl mercury (1.5 months) making exposure to ethyl mercury in blood comparatively brief. Further, ethyl mercury is actively excreted via the gut unlike methyl mercury that accumulates in the body.
