The court found the HHS's decision to replace the advisory committee was improper and ignored established scientific procedures.
March 20, 2026

A U.S. District Court Judge has made a decision to halt the implantation of the Advisory Committee on Immunization Practices’ (ACIP) childhood vaccine schedule updates, according to an NPR report.

The ruling called U.S. Department of Health and Human Services (HHS) Secretary Robert F. Kennedy Jr’s decision to replace the entire committee “improper.” The new members are now “stayed” by the ruling. It also stated that the new vaccine schedules ignored “a long-used, well-regarded scientific process for developing vaccine policies.” NPR reported that HHS is working to have the U.S. District Court Judge’s decision overturned.

According to the Infectious Diseases Society of America (IDSA), AAP et. al. v Kennedy et. al. is set to proceed, and the court has refused the government’s request to dismiss the case.
