Significant shares of adults with multiple or complex health conditions, including cancer, lung disease, diabetes, cardiovascular disease, and mental health conditions say they struggle to pay their medical bills and access needed care and medication. These challenges fall hardest on uninsured adults who face greater costs and access challenges.
In a new column, Dr. Drew Altman, KFF’s Founding President and CEO, previews findings about the chronically ill uninsured from a large KFF survey of 25,000 Americans focusing on the cost and access challenges facing the chronically ill, which will be released tomorrow. He writes: “There are more than enough needs to go around in American health care, but if I had to pick the one group that struggles the most with costs and access, it would be people with chronic illnesses who are also uninsured.”
This data note reviews recent KFF polling data about Americans' struggles to afford many aspects of health care, including disproportionate shares of uninsured adults, Black and Hispanic adults, and those with lower incomes.
On August 5, 2026 the U.S. Food and Drug Administration approved the first-ever mRNA flu vaccine for adults 50 and older, following a trial of roughly 40,000 people. KFF polling in April 2025 found that most adults ages 50 and older were uncertain whether mRNA vaccines are safe.
Drawing on KFF’s poll findings, this interactive dashboard tracks the public’s trusted sources for health information, attitudes toward vaccines, and use of news, social media, and AI for health-related information.
Amid an ongoing FDA re-review of mifepristone, awareness of the safety and prevalence of the abortion pill remains limited. This KFF poll also finds that the voters who say abortion policy is an important issue for 2026 midterm candidates to discuss are disproportionately Democrats.
Much of the public has yet to form an opinion on the U.S. government’s response to the Ebola outbreak in the Democratic Republic of the Congo, this poll finds. Four in ten adults say the U.S. is less prepared for a pandemic now than it was in 2020.
As the 2026 midterms approach, health care costs remain voters’ top health priority, but fraud in government health programs, including Medicaid and Medicare, is resonating with Republican voters, 55% of whom say it’s extremely important for candidates to address.
This KFF Health Tracking Poll finds that the cost of health care is a more prominent focus for Make America Healthy Again (MAHA) voters than issues like food and vaccine policy. Four in ten MAHA voters (42%) choose lowering health costs as the most important health priority, outranking other MAHA priorities.

The 2025 Survey of Immigrants, a partnership between KFF and The New York Times, takes an in-depth look at the experiences of immigrants during the first year of President Trump’s second term, including their worries related to increased immigration enforcement, their health and economic wellbeing, and the political views and preferences of immigrant voters. The survey paints a portrait of families under strain — where fear of detention and economic instability are negatively impacting immigrants’ health and reshaping immigrant families’ daily lives and views of U.S. political parties.
