Aluminum in Vaccines and Asthma?

Published on

Vaccine News

Aluminum is used in some vaccines as an adjuvant. Adjuvants enhance the immune response to vaccines, allowing for use of lower quantities of antigen in the vaccine and fewer doses. Aluminum adjuvants have been safely used in vaccines since the 1930s. However, unfounded concerns about the safety of aluminum in vaccines have been voiced over the years.

Recently, a study was published in which the results suggested an association between aluminum in vaccines and the development of asthma. While on its face this sounds concerning, it is important to evaluate how the study was done. In this video, Dr. Paul Offit describes important methodological flaws that limit what we can learn from this study and why parents should not be concerned about the safety of the current immunization schedule based on these data.
