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.
Data show that children’s vaccination rates, including MMR and seasonal flu vaccines, have declined in recent years largely due to decreases in vaccinations among White and Asian children. At the same time, and despite the declines among White and Asian children, Black and AIAN children remain least likely to have received recommended childhood vaccinations and the MMR vaccine specifically.
Starting in May of last year, HHS Secretary Kennedy and the CDC/ACIP began to make changes to the federal vaccine schedule for children, culminating in an announcement on January 5 of this year with the most wide-ranging changes to date. This policy brief tracks the number of states that have announced they are no longer following federal government recommendations for childhood vaccines as of January 20, 2026.
This brief examines U.S. policy options for helping expand global access to COVID-19 vaccines, focusing on four main areas: in-kind donations of vaccine doses, additional funding for global access mechanisms like COVAX, helping expand global vaccine manufacturing, and relaxing or waiving intellectual property protections on vaccine technologies. We summarize what the administration has done to date in these areas and policy issues related to each.
These findings from a KFF/Washington Post survey reveal how parents encounter information related to children's health on social media, including trust in content they see online and whether they have specific, trusted influencers when it comes to information about children's health.
This report finds that 72% of adults now report being at least partially vaccinated for COVID-19, with the surge in cases, hospitalizations, and deaths due to the Delta variant being the main motivator for the recently vaccinated. It also examines the public's views on vaccine mandates, booster doses, and breakthrough infections.
The Survey on Race and Health is a joint project between KFF and ESPN’s The Undefeated exploring the public’s views and experiences on health care, racial discrimination, and the coronavirus pandemic. It includes a special focus on the views and experiences of Black Americans, including unconscious bias and structural racism; experiences and trust in the health care system; the social and economic impacts of the pandemic; and views of a potential COVID-19 vaccine.
This volume shares updates from the most recent CDC advisory panel meeting, changes to the CDC webpage on autism and vaccines, and polling on trust in news organizations. Additionally, it shares recent developments in AI and social media policy and new KFF poll findings about perceptions of mifepristone’s safety and prevalence.
This volume examines findings about trusted sources of vaccine information from the latest KFF Tracking Poll on Health Information and Trust. It also explores how the misrepresentation of studies and policy developments contribute to health narratives around vaccines, HIV and PrEP. Lastly, it summarizes new research on the use of generative AI to counteract vaccine misinformation.
This volume analyzes false narratives about autism rates in Cuba and among Amish people in the U.S.; health-related cases before the Supreme Court, including challenges to bans on conversion therapy for LGBTQ+ minors and school vaccine mandates; and the limitations of AI chatbots as primary sources of health information.
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.
