How do we know if the aluminum in vaccines is safe? [NvrMxwWCnJu]

Aluminum is the most common heavy metal on Earth. It’s in our water, soil, plants, and even in the air. We are always in contact with it. We eat aluminum when we eat foods like vegetables, fruit, or milk. When we get aluminum from a vaccine we inject in it a muscle. Whether eaten or through vaccination, the aluminum enters our blood stream and is taken out of the body by our kidneys. When a vaccine is given, the level of aluminum in the blood does not rise afterwards. Aluminum can be harmful if you have kidneys that do not work, are born prematurely, or are exposed to large quantities of aluminum for months or years. Vaccines do not cause that type of exposure.
