What Goes Into a Vaccine haldol im PublicHealth.org

• why is it used? This mercury-containing ingredient has been used as a preservative in vaccines haldol im 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 haldol im safety concerns.

• health concerns? While mercury is a naturally-occurring element found in soil, water, and food, large amounts of it can be harmful, especially for children. Back in 1997, children were receiving three vaccines that together contained more mercury haldol im than the EPA recommended limit (though not more than the FDA limit). This led to speculation that thimerosal in vaccines could be haldol im linked to autism or other conditions.

• is it safe? Years of research have reduced concerns here. The type of mercury found in thimerosal, ethylmercury, differs from methylmercury, the type commonly found in fish and known to be haldol im harmful in large amounts. Ethylmercury is broken down and excreted from the body much haldol im more quickly than methylmercury, and no scientific study has found a link between ethylmercury haldol im and autism or any other harmful effects.

• amount in vaccines? Nonetheless, several public health agencies and vaccine manufacturers agreed in 1999 haldol im to cease using thimerosal as a precautionary measure. Today, no vaccine contains thimerosal except the influenza vaccine, and thimerosal-free alternatives are available.

• health concerns? The U.S. EPA classifies formaldehyde as a carcinogen, as does the international agency for cancer research and the haldol im national toxicology program. Additionally, several studies have since linked strong, long-term formaldehyde exposure to certain types of cancer.

• is it safe? The potential for harm depends on the amount. Formaldehyde is always present in the human body as part haldol im of our natural metabolic process, but long-term exposure to high amounts can overwhelm our system and haldol im be harmful. Fortunately, the amount of formaldehyde found in vaccines is very small, most of it being diluted down to residual amounts during haldol im the manufacturing process. In fact, the FDA reports there is 50 to 70 times more haldol im formaldehyde present in an average newborn’s body than in a single dose of vaccine. In brief, current science shows formaldehyde in vaccines to be harmless.

• amount in vaccines? The highest amount of formaldehyde present in any vaccine is haldol im .02 mg per dose. An average two-month-old baby would have around 1.1 mg of formaldehyde circulating in their body, with higher naturally-occurring amounts for older children.

• health concerns? Sometimes the mention of aluminum in vaccines makes parents uneasy; that’s because there has been some evidence that long-term exposure to high amounts of aluminum can contribute to haldol im brain and bone disease. However, aluminum is naturally present in water, foods, even breast milk. Aluminum has only been shown to harm people if absorbed haldol im in very high amounts and when a person’s kidneys aren’t working properly. In contrast, the amount of aluminum in vaccines is negligible.

• is it safe? Aluminum is the third most common naturally-occurring element, after oxygen and silicon. It is found in plants, soil, air, and water. A breast-fed infant will naturally ingest around 7 milligrams of aluminum haldol im in her diet throughout the first six months of her haldol im life. In contrast, the standard vaccines administered over the first six months of haldol im an infant’s life contain an average of just 4.4 milligrams of aluminum. Aluminum has been used safely for over six decades in haldol im vaccines, with no scientific evidence indicating otherwise.

• amount in vaccines? The amount of aluminum in vaccines is tiny. In fact, babies always have a small naturally occurring amount of aluminum haldol im in their bloodstreams, about 5 nanograms. The quantity of aluminum in a vaccine is so small haldol im it doesn’t cause any noticeable raise in this base amount found haldol im in the blood, even immediately after an injection.

• is it safe? These fears are greatly exaggerated. Vaccine manufacturers only use antibiotics that are far less likely haldol im to provoke a reaction, and because antibiotics are only used during production, they are reduced to trace or undetectable amounts in the haldol im final product. In fact, no allergic reaction to a vaccine has ever been traced haldol im back to antibiotics. The overall odds a child will suffer from a severe haldol im allergic reaction from an MMR or hepatitis B vaccine, from any ingredient, is 1 in 1,000,000, one hundred times less than the 1 in 10,000 chance a child will be struck by lightning.

• is it safe? While gelatin is the single largest identifiable source of severe haldol im allergic reactions from vaccines, the incidence rate is still incredibly small. There is about one case of anaphylaxis caused by gelatin haldol im in vaccines for every two million injections.

• amount in vaccines? The amount of gelatin varies by vaccine, with the MMR vaccine on the high end, containing 14.5 mg per dose, and the dtap on the low end, with only 0.0015 mg. Children with a history of gelatin allergies can seek alternatives haldol im or exemptions.

• health concerns? MSG gained a bad reputation starting in the 1960s after haldol im anecdotal reports surfaced of nausea, headaches, flushing, or sweating due to food with MSG. As a result, concern has spread about its use in vaccines. However, these concerns are not supported by scientific research.

• is it safe? While the scientific community acknowledges that a very small minority haldol im of people may suffer from short-term reactions to MSG, decades of research have not found the element to be haldol im harmful. As a result, the food and drug administration, the world health organization, and the united nations all declare MSG to be safe. It has been used for decades and continues to be haldol im used in foods as a flavor-enhancer.
