NIH Clinical Center board chair warns against political interference in research
Jack Leslie, chair of the NIH Clinical Center board, has criticized Robert F. Kennedy Jr.’s recent establishment of a vaccine injury clinic within the hospital, citing risks to institutional credibility.

Jack Leslie, chair of the board overseeing the National Institutes of Health (NIH) Clinical Center, has publicly challenged the integration of a vaccine injury clinic led by Health Secretary Robert F. Kennedy Jr. into the research facility. During a recent board meeting, Leslie argued that the clinic’s operational approach could undermine the reputation of the hospital, which serves as a primary site for rare disease research.
The tension stems from a surprise ribbon-cutting event held at the facility, where Kennedy appeared alongside individuals claiming vaccine-related injuries. Leslie stated that the advisory board has a responsibility to speak out when the institutional integrity of the 'house of hope' is at risk, noting that while vaccine side effects should be studied, the manner of the clinic's introduction is problematic.
While Leslie acknowledged that serious vaccine reactions are a factual concern and that affected patients deserve care, his comments signal growing concern among NIH leadership regarding political influence in clinical operations. The controversy highlights a broader debate over how political figures interact with established medical research institutions.
