Is aluminum in vaccines causing allergies?

In a video, RFK Jr. claims that aluminum adjuvants in vaccines may trigger lifelong allergies to various substances by provoking immune responses.

Aluminum salts have been used as adjuvants in vaccines since the 1930s to enhance immune responses. Extensive research has evaluated their safety profile. The American Academy of Allergy, Asthma & Immunology notes that while aluminum-containing allergen vaccines are used to treat allergic conditions, there is no evidence of any long term effect on allergic disease. While an individual study or preprint might claim otherwise, comprehensive reviews have found no credible evidence linking aluminum in vaccines to an increased risk of allergic conditions

Vaccines undergo rigorous testing for safety and efficacy before approval. The CDC states that aluminum-containing vaccines have a strong safety record, and there is no credible evidence to suggest they cause allergic diseases.

Humans are regularly exposed to aluminum through various sources, including food, water, and the environment. The amount of aluminum present in vaccines is minimal compared to daily exposures from other sources. The Children’s Hospital of Philadelphia emphasizes that the quantity of aluminum in vaccines is small and not harmful to human health.

Finally, vaccines do not contain secret, hidden ingredients, including peanut oil. All vaccine ingredients, including those found in amounts too small to measure (less than one microgram), are listed.
