Health and Human Services Secretary Robert F. Kennedy Jr. is directing a significant research initiative focused on vaccines within his department, according to reports, even as he has reduced his public criticism of vaccination programs since taking office.

Kennedy, who previously expressed skepticism about vaccine safety and efficacy, has reportedly scaled back his public statements on the topic following guidance from the White House. However, sources indicate that vaccine-related research remains a priority within the Health and Human Services Department under his leadership.

Separately, reports have emerged that President Trump has approved a plan to remove Food and Drug Administration Commissioner Marty Makary from his position. Makary has served as FDA commissioner since March 2025, overseeing the agency during a period of continued focus on drug and vaccine regulation.

The potential leadership change at the FDA comes amid broader discussions within the administration about health policy direction and regulatory oversight. The FDA plays a central role in vaccine approval and safety monitoring processes.

Neither the White House nor the Health and Human Services Department immediately responded to requests for comment about the reported research initiatives or the planned FDA leadership change. The timing and scope of any potential personnel moves remain unclear.
