The independent source for health policy research, polling, and news.
KFF’s policy research provides facts and analysis on a wide range of policy issues and public programs.
KFF designs, conducts and analyzes original public opinion and survey research on Americans’ attitudes, knowledge, and experiences with the health care system to help amplify the public’s voice in major national debates.
KFF Health News is a national newsroom that produces in-depth journalism about health issues and is one of the organization’s core operating programs.
The latest KFF Health Tracking Poll shows that Secretary Kennedy continues to be popular among President Trump’s MAGA base and somewhat popular among supporters of his Make America Healthy Again (MAHA) movement, but his appeal beyond those two groups is limited.
This policy watch examines the United States’ measles elimination status, including what it means to eliminate measles, whether the current measles outbreak could threaten the country’s measles elimination status, and what losing that status might mean for measles control.
KFF's latest Tracking Poll finds that one-third of the public report using AI chatbots for health information and advice in the past year. And a federal judge suspended, for now, the appointments of thirteen members of ACIP, halting a scheduled meeting and staying recent, widely debated, changes to the childhood vaccine schedule.
About a third (32%) of adults nationally say they have turned to artificial intelligence (AI) chatbots in the past year for health information, a new KFF Tracking Poll on Health Information and Trust finds. Most who turned to AI for health information say they were in search of quick and immediate advice, though challenges affording and accessing health care also play a role, particularly for younger adults.
A growing number of states, reaching 30 as of March, have announced that they are no longer following CDC recommendations as their benchmark for some or all childhood vaccines... The court’s stay does not change these states’ decisions and in some ways may allow them to avoid a potential ‘ping pong’ of federal vaccine policy that could result from future legal rulings or actions by the administration.
The EPA launched the next step of its fluoride safety review, as more states move to ban community water fluoridation and senior officials amplify concerns about fluoride beyond what current evidence supports. The Monitor also explores AI policy and content moderation, including the practice of GEO to influence what AI chatbots say.
In his latest column, President and CEO Dr. Drew Altman discusses how midterm political strategy will shape health policy in 2026, focusing on recent moves by President Trump. He writes: “Democrats start out with a significant advantage on health in the midterms, but rather than cut and run to other issues, Trump wants Republicans to try to erode that advantage where they can.”
A new study finds that nearly 10% of cancer research papers showed signs of being fabricated by “paper mills”. The problem may intensify as generative AI becomes more sophisticated, prompting lawmakers to demand information about safeguards in place. And, claims that physicians are financially incentivized to promote vaccines persist, despite lack of evidence.
KFF experts shared insights on what the shifting policy for childhood and adult vaccination schedules means for state governments, the U.S. public health system, and Americans.
In the weeks after the Trump administration reduced the number of recommended childhood vaccines for routine use, the public’s trust in the CDC remains at its lowest point. Among those who have heard about the recent changes to the recommended childhood vaccine schedule, more say they expect the changes to have a negative impact than a positive one on children’s health.
