Is aluminum in vaccines safe?

U.S. health officials plan to remove an ingredient used in vaccines for decades: aluminum. So, is aluminum in vaccines safe?

The U.S. Department of Health and Human Services (HHS) has restricted certain vaccines, dropped recommendations for COVID-19 vaccination for children and pregnant women, and set a goal of eliminating thimerosal (a mercury-based preservative) from vaccines in the U.S.

In a press conference on September 22, US President Donald Trump advised pregnant women against using Tylenol. He also mentioned that the Washington administration is in the process of removing aluminum (used as an adjuvant) from vaccines.

On October 8th, the Advisory Committee on Immunization Practices (ACIP) of the Centers for Disease Control and Prevention (CDC) announced a new working group focused on childhood immunization schedules, with discussion topics including vaccine safety components and "aluminum adjuvants".

According to Politifact on October 17, ACIP is expected to determine there is "a lot of evidence" about "problems" related to aluminum in vaccines. The committee may vote to classify vaccines containing aluminum adjuvants, and people must discuss this with their doctor before vaccination.

However, experts told Politifact that scientific research does not support removing aluminum adjuvants from vaccines.

Since the 1920s, aluminum adjuvants have been used in some vaccines to help boost the body's immune response. Aluminum-containing vaccines contain only a very small amount of this adjuvant: less than 1/1,000 gram per dose.

Aluminum occurs naturally in the air, soil, and water, and humans are exposed to it every day. Food is also a major way for humans to come into contact with aluminum.

According to the CDC, the average adult consumes about 7-9 mg of aluminum per day. Infants in their first six months receive about 4.4 mg of aluminum from recommended vaccines. Breastfed babies also absorb about 7 mg of aluminum from breast milk and 38 mg of aluminum from formula.

There is ample evidence from clinical trials in animals and humans supporting the efficacy and safety of all vaccines, including aluminum-containing vaccines. A large body of research also indicates that aluminum adjuvants do not cause aluminum toxicity or other adverse effects.

Furthermore, vaccine experts say that removing aluminum from vaccines would significantly reduce their ability to protect against vaccine-preventable diseases.

The CDC states that at least 25 vaccines approved for use in the U.S. contain aluminum adjuvants. These include vaccines against HPV, hepatitis A and B, diphtheria, pertussis, and tetanus.
