**RFK Jr. remains active as HHS Secretary in August 2026, advancing the Make America Healthy Again agenda through vaccine policy reviews, leadership reorganizations, and public health initiatives aligned with President Trump’s executive actions.** Recent steps include an HHS request for public comment on vaccine recommendation categories and timing following Trump’s August executive order limiting childhood schedules, plus announcements on autism safety partnerships and food policy. Trump has hosted Kennedy and voiced support for these priorities, with no reported White House pressure or signals of removal. While polls show mixed or negative overall approval and some health groups have called for resignation, Kennedy retains strong backing from the MAGA base. Legal challenges to certain advisory changes have slowed implementation but have not disrupted his tenure or prompted departure. Traders see limited near-term risk of exit by year-end, as the administration continues to prioritize his role in health policy execution.
