Health and Human Services Secretary Robert F. Kennedy Jr. is moving to remake an influential health panel that determines what preventive medical services insurers must cover at no cost. Kennedy has blocked the panel from meeting multiple times, declined to replace members whose terms expired, and fired its leaders in May.

The actions signal Kennedy's continued push to reshape federal health agencies and policies. The panel plays a significant role in determining access to preventive care services across the country, making its composition and direction a matter of broad public health impact.
