Does aluminum in vaccines cause allergies?

An old video with RFK Jr. has him talking about aluminum adjuvants in vaccines causing allergies in children.

• One paper suggests a theory but does not prove vaccines cause food allergies.
• A review of over 190 studies found no link.
• Allergies appearing after vaccination do not mean vaccines caused them.

The paper this claim is based on is from SSRN, a website where researchers can share papers early,  before experts review them. A full version is also available in the Journal of Developing Drugs. The paper suggests ways vaccines might cause food allergies, but it does not show that they actually do.

A large research review in JAMA Pediatrics combined results from more than 190 studies involving over 2 million people. Researchers looked at more than 300 possible risk factors: things that might raise a person’s chance of developing food allergies. They found no link between vaccines and food allergies.

As Dr. Navard-Keck at Children’s Hospital of Philadelphia explains, food allergies often appear during the same years that children get vaccines. This timing can make the two seem connected. But an allergy that appears after a vaccine was not necessarily caused by it.
