Immunologist warns vaccine order could erode trust in science and harm kids

The president of the American Association of Immunologists argues that a recent executive order on childhood vaccines contradicts established scientific evidence and could undermine public confidence in immunization. The order proposes changes to the vaccine schedule and splitting the MMR shot, which the author says bypasses the transparent expert review process that has guided U.S. vaccine policy for decades. Even if the order doesn't immediately alter policy, it sets a dangerous precedent by replacing scientific guidance with political directives.

The executive order proposes altering the U.S. childhood vaccine schedule and splitting the combined MMR vaccine into separate shots. Dr. Avery August, president of the American Association of Immunologists, emphasizes that U.S. vaccine policy has historically relied on a transparent review process involving scientists, physicians, and public health experts. He notes that constructive disagreement is normal in such deliberations but argues that replacing expert guidance with political directives sets a dangerous precedent. The order lacks direct authority to change vaccine recommendations, which remain protected by federal law, and pediatricians and state agencies may continue following established schedules.
