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.
This new analysis examines the experiences of LGBT adults from the July COVID-19 Vaccine Monitor and finds that as a group they are more likely to be vaccinated for COVID-19 and less likely to view getting the vaccine as a health risk compared to non-LGBT adults. A larger share of LGBT adults than non-LGBT adults say they have received at least one dose of a COVID-19 vaccine (82% vs 66%) and are more supportive of…
This brief answers key questions about the U.S. monkeypox outbreak to date and identifies issues that may affect the response going forward.
This analysis examines monkeypox vaccine allocations and jurisdictional requests. It explores jurisdictional request rate (the number of vaccine does requested as a share of the jurisdiction’s allocation from HHS) for JYNNEOS, the preferred vaccine. Overall, while most jurisdictions have requested at least their full supply, some are well below that mark, raising questions about how quickly their at-risk populations can get protected.
In this issue, we take a closer look at the reliability of artificial intelligence (AI) chatbots as a source of health information. We explore public opinion on chatbot accuracy based on KFF surveys and highlight recent examples of AI-generated election misinformation in the news. In addition, we share our firsthand experience querying AI chatbots on health topics and discuss research on gaps in safeguards.
The latest KFF COVID-19 Vaccine Monitor survey reveals that half (51%) of all adults nationally say they “definitely” or “probably” will not get the latest COVID-19 vaccine, with many saying that they aren’t worried about catching the virus. One in five (20%) say that they’ve already gotten the new vaccine that became available in September, with an additional 28% saying they “definitely” or “probably” will get the new shot. The rest say they “definitely” or…
It is unclear how the MAHA Commission will square its goal to “tackle the health crisis facing America” with such major challenges not addressed and a shrinking, less capable health infrastructure.
Given the current trends and embrace of vaccine skepticism on the part of the administration, and potential changes to federal policy around childhood vaccines, we might continue to witness more and longer outbreaks of preventable disease — and just maybe lose our measles elimination status, which as a country we’ve had for 25 years.
… declining trust in the CDC and in the benefits of childhood vaccinations may complicate any efforts to address emerging public health challenges like the ongoing measles outbreak and the continued threat of bird flu
This volume discusses the spread of race-based vaccine myths and shifts in health communication from fact-checking to fostering open dialogue. It also explains common misconceptions about heart attack treatment and prevention, a new scientific journal that questions established science, and gaps in research standards for AI chatbots used in healthcare.
This volume highlights how a report criticized for flawed methodology is influencing renewed efforts to restrict access to mifepristone; a federal plan to study the causes of autism that could be contributing to stigma by over-emphasizing environmental toxins; and the resurgence of false claims about fetal tissue in vaccines.
