The vaccine safety panel advising the Centers for Disease Control and Prevention discussed on Friday the use of aluminum in vaccines and the connection between vaccine ingredients and autism, a controversial topic that is sure to further set the panel at odds with many medical professional groups and split Republicans.

The discussion did not result in any policy changes affecting the availability of vaccines. Still, it signaled that the committee could make changes to vaccine ingredient recommendations in 2026, which would be a significant win for the antivaccine wing of the Make America Healthy Again movement.
