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.
During the 55th week since the first coronavirus case appeared in the United States, the world is at nearly 108 million COVID-19 cases. The U.S. approached 27.4 million cases and a total of 475,400 deaths.
This brief reviews why racial diversity within COVID-19 vaccine clinical trials is important, discusses the barriers to participation in clinical trials among people of color, and examines the racial/ethnic composition of clinical trial participants for the Pfizer-BioNTech and Moderna vaccines.
Across states, data to understand access to and uptake of the vaccine by race/ethnicity and other demographic factors will be central to efforts to ensure equity. KFF is compiling and will regularly update state-reported data on vaccination by race/ethnicity through its COVID-19 state data and policy tracker.
This report shows an increasing share of the public are frustrated about the status of COVID-19 vaccinations in the U.S.. The share of fully vaccinated adults who report receiving a booster dose has more than doubled in the last month, though vaccine uptake overall is little changed. The poll also explores attitudes towards federal mandates on workplace vaccinations and the pandemic's toll on different groups.
This report finds the public is generally supportive of U.S. distribution of vaccines internationally, though more likely to prefer the U.S. playing a major role versus a leading one, and there are partisan differences. The analysis also examines how different information affects the public's views.
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.
As rates of childhood vaccination decline and with measles on the rise again, a KFF Health Misinformation Tracking Poll, fielded in late February, examines the extent to which adults have heard and believe misinformation about the measles vaccine.

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.
