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.
KFF is collecting and analyzing data on COVID-19 vaccinations by race/ethnicity to gain increased insight who is receiving the vaccine and whether some groups are facing disparities in vaccination.
While the federal, state, and survey data all show narrowing racial disparities in COVID-19 vaccination rates over time, they vary in the magnitude of this narrowing, with some surveys showing that gaps have closed, while the administrative data pointing to some remaining differences. This variation in findings reflects both differences and limitations across the datasets.
This fact sheet offers a look back at 10 issues that KFF tracked closely during 2023 in its polling, policy analysis and journalism, including summaries of major findings and news stories.
With recent federal actions to curtail vaccine access, many states have announced actions intended to maintain broader access. This issue brief provides a snapshot of this rapidly changing landscape, tracking which states have instituted changes in response to or in anticipation of administration policy changes.
With supply having increased significantly and eligibility fully open to adults in all states as of April 19, this analysis estimates that COVID-19 vaccine supply will exceed demand across the U.S. over the next 2 to 4 weeks.
In this Axios column, Drew Altman says full FDA approval of COVID-19 vaccines can provide a big boost to vaccination efforts if treated as an opportunity for updated messaging from government officials at all levels and public health experts and new actions from employers.
This report explores the roughly a third of adults who have not received a COVID-19 vaccine and finds that, compared to vaccinated adults, they are younger, more likely to identify as Republican or Republican-leaning, with lower incomes and education levels, and more likely to be uninsured.
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.
This brief examines key policy challenges and issues related to distributing a COVID-19 vaccine in the U.S., including funding, supply and logistics, federal, state, and local authorities, insurance coverage, addressing racial and ethnic disparities, and communication and trust.
As the Trump administration overhauls government health agencies, partisan trust in these agencies on vaccines has shifted and few express confidence in their ability to carry out key tasks. Most adults are confident in the safety of routine vaccines, but the COVID-19 vaccines remain polarizing with many uncertain about false claims regarding mRNA technology.
