The Trump administration has filed an appeal following a federal judge’s decision last month that temporarily halted vaccine policy changes implemented by Health Secretary Robert F. Kennedy Jr. at the Centers for Disease Control and Prevention (CDC).

The changes, which included filling a key vaccine advisory panel with anti-vaccine allies and unilaterally reducing childhood vaccine recommendations, were blocked by Judge Brian Murphy of the U.S. District Court on March 16.

In his ruling, Judge Murphy issued a temporary injunction that:

  • Prevented the appointment of Kennedy’s advisors to the CDC’s vaccine panel;
  • Nullified all votes made by these advisors on federal vaccine policy;
  • Reversed the changes made to the CDC’s childhood vaccination schedule.

Murphy determined that Kennedy’s advisors were unqualified and that their appointment, along with the vaccine recommendation changes, violated federal procedures. His ruling came in response to a lawsuit filed by the American Academy of Pediatrics (AAP) against Kennedy and the Department of Health and Human Services (HHS).

Prior to the ruling, government lawyers had argued that Kennedy’s authority was so broad that he could legally advise Americans to inject themselves with the measles virus instead of receiving the vaccine. Judge Murphy rejected this argument, stating that the AAP was likely to succeed in proving that Kennedy’s actions were illegal.
