Is aluminum in vaccines safe?

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

During a press conference on September 22, US President Donald Trump advised pregnant women not to use Tylenol. In addition, he also mentioned that the Washington government has been in the process of removing aluminum (used as an excipient) from vaccines.

On October 8, the Advisory Committee on Immunization Practices (ACIP) of the Centers for Disease Control and Prevention (CDC) announced a new working group focusing 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 that there is "a lot of evidence" of "problems" related to aluminum in vaccines. The committee may vote to classify vaccines containing aluminum adjuvants and people must discuss with their doctor before getting vaccinated.

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 tiny amounts of this adjuvant: less than 1/1,000 of a gram per dose.

Aluminum occurs naturally in air, soil, and water, and humans are exposed to aluminum every day. Food is also a major route of human exposure to aluminum.

According to the CDC, the average adult ingests about 7 to 9 mg of aluminum per day. Infants in the first six months of life 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 a large body of evidence from animal and human clinical trials supporting the efficacy and safety of all vaccines, including those containing aluminum. A large body of research also shows that aluminum adjuvants do not cause aluminum toxicity or other adverse effects.

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

The CDC says at least 25 vaccines approved for use in the United States contain aluminum adjuvants. These include vaccines for HPV, hepatitis A and B, diphtheria, pertussis, and tetanus.
