Are they using unnatural aluminum in vaccines?

A new claim says that the aluminum used in some vaccines is not the same as the aluminum found in food or nature. It says this aluminum is changed in a lab and then injected into the bloodstream. The claim argues that the body reacts strongly to it, and that this reaction could be linked to allergies, autism, and other health problems.

No matter how aluminum gets into your body, a small amount can end up in your blood. If you eat or drink aluminum from food, some of it can pass from your stomach and intestines into your blood. From there, your body sends it to the kidneys and liver. These organs help filter and remove things your body does not need.

Some vaccines also contain small amounts of aluminum salts. Aluminum salts are forms of aluminum, such as aluminum hydroxide or aluminum phosphate. They are added to some vaccines as an adjuvant. An adjuvant is an ingredient that helps the vaccine work better by helping the immune system notice and respond to the vaccine.

Vaccines with aluminum are not injected straight into the bloodstream. They are usually given into a muscle or under the skin. Over time, the aluminum can move into the blood as the body processes it and sends it to the kidneys and liver.

Aluminum has been used in some vaccines for many decades. The article says aluminum adjuvants have a safety record of more than 60 years. Because we are exposed to aluminum in food every day, but only get vaccines once in a while, most of the aluminum that enters the blood comes from our diet, not vaccines.
