ASK THE CPCMG PEDIATRICIAN: I read on the internet that vaccines contain metals like aluminum which can hurt my child. Is this true?

As parents, it’s natural to have questions about what goes into the vaccines that help protect your children from serious diseases. One ingredient that often comes up for debate is aluminum. Let’s take a moment to talk about this mineral, why it’s used, and why it’s safe.

What is aluminum?
Aluminum is a metal that is found in the earth’s crust. Commercially produced aluminum is used in food-related products like pots and pans; storage containers, such as beverage cans; and foil. Aluminum is found in numerous foods and beverages including fruits and vegetables, beer and wine, seasonings, flour, cereals, nuts, dairy products, baby formulas, and honey. It’s important to note that our bodies absorb only a small amount of the aluminum we take in with our food.

Why Is Aluminum in Vaccines?
Aluminum has been used in vaccines for more than 70 years. It’s not there as a preservative—it’s used as an adjuvant. This means it helps the body build a stronger immune response to the vaccine, so your child gets better protection with fewer doses.

Is Aluminum Safe for Kids?
Yes, because the amount of aluminum in vaccines is very small and well within safe limits. Health authorities like the CDC, FDA, and World Health Organization have all studied aluminum in vaccines extensively. The conclusion is clear: it’s safe.

Vaccines save lives, and ingredients like aluminum help them do their job more effectively. If you have questions or concerns, please reach out to your CPCMG pediatrician to talk them through.
