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.
Twenty-two states and the District of Columbia have vaccinated at least one-third of their residents who are 65 and older against COVID-19, an updated KFF analysis finds, but no state has crossed the threshold of vaccinating 50 percent or more of its older population.
This issue brief presents current state-level data about COVID-19 cases and deaths in settings that primarily serve nonelderly people with disabilities and summarizes available research on this population’s elevated risk of severe illness and death; explains how nonelderly people with disabilities and their LTSS providers are reflected in state vaccine prioritization plans; and discusses key issues related to vaccine access for these populations.
The Latest KFF COVID-19 Vaccine Monitor finds a growing share of U.S. adults say they have already gotten at least one dose of the vaccine or want to get vaccinated as soon as possible. Black and Hispanic adults remain more likely to want to wait and see how the vaccine is working for others before getting it themselves.
Here's a breakdown of how states are including “high-risk medical conditions” in their vaccination priority groups. Among the 50 states and DC, 37 have provided explicit information on what conditions they consider “high risk.” Learn more in this Chart of the Week.
This analysis examines COVID-19 vaccination rates among older adults in states that report these data at the person-level. It also looks at the change in vaccination rates between February 4 and February 23 among a subset of these states.
The number of residents contracting and dying of COVID-19 in nursing homes has declined markedly following the introduction of vaccination efforts in long-term care facilities, a KFF analysis finds. Resident deaths from COVID-19 in nursing homes have decreased by two-thirds (66%) since vaccination efforts began in late December.
This analysis compares trends in new COVID-19 cases and deaths among nursing facility residents with trends in all other new COVID-19 cases and deaths excluding nursing facility residents through February 7, 2021. This analysis shows a marked divergence in new cases and deaths per week between nursing facility residents and the rest of the US population since December 2020. This drop in new deaths and cases in nursing facility residents coincides with the start of vaccine administration in LTCFs, suggesting a link between the two, although the trends could also be influenced by other factors.
This issue brief explores the impact of COVID-19 on justice-involved populations, examines how states have prioritized these populations for vaccination, and highlights the significance of Medicaid coverage for this population as well as proposals to expand access to Medicaid coverage.
This policy watch piece highlights the potential challenges surrounding COVID-19 vaccinations among Hispanic people, whose health and finances have been extremely hard hit by the pandemic. Low rates of vaccination among Hispanic people would leave them at increased risk for the virus, could further widen existing health disparities, and would leave gaps that hinder our ability to achieve overall population immunity.
KFF has an updated analysis of state-reported data as of February 16, 2021 on COVID-19 vaccinations, cases, and deaths by race/ethnicity. New to the analysis are comparisons of vaccination rates in each racial/ethnic group based on state-reported data of total people who have received at least one dose of the vaccine.
