A number of scientists have wondered if aluminum, a vaccine additive that has been used for decades, had a role in allergies and asthma in children.
FILE - An infant receives a routine vaccination in Fayetteville, Ga., Tuesday, Aug. 17, 2021. Years ago, the government set out to determine if aluminum in vaccines could be driving growing rates of allergies and asthma in children. A federally funded study released Friday, Sept. 23, 2022, has found a possible link between aluminum and persistent asthma. But experts say the study has several shortcomings and is not a reason to change current vaccine recommendations.
“Making an extraordinary claim requires extraordinary evidence,” Offit said. This study does not offer that kind of evidence, he said. Aluminum has been used in some vaccines since the 1930s, as an ingredient — called an adjuvant — that provokes stronger immune protection. “Based on what I consider limited animal data, there is a theoretical risk that the aluminum in vaccines could influence allergy risk,” said Daley, an associate professor of pediatrics at the University of Colorado School of Medicine.
Asthma, a condition that can cause spasms in the lungs, usually results from an allergic reaction. About 4% of U.S. children under 5 have persistent asthma. Both groups got roughly the same amount of vaccine-related aluminum. The researchers found that for each milligram of aluminum received through vaccines, the risk of persistent asthma rose 26% in the eczema kids and 19% in kids who did not have eczema.
