KFF Health Information and Trust Polling Dashboard

Doctors and other health care providers are the public’s most trusted source of health information, while trust in government health agencies and officials is much more divided. A large majority of adults express at least “a fair amount” of trust in their doctor for reliable information about health issues, while half say they trust the CDC or FDA and fewer than half express trust in their state government officials, HHS Secretary Robert F. Kennedy, Jr., or President Trump.

Partisanship shapes who the public trusts for health information, especially when it comes to Secretary Kennedy and President Trump. Roughly six in ten Republicans, rising to at least seven in ten among MAGA-supporting Republicans, say they trust Secretary Kennedy or President Trump for reliable health information compared to three in ten or fewer independents and Democrats who say the same. On the other hand, Democrats are more likely than Republicans to trust their state officials for health information, while similar shares of Democrats and Republicans say they trust the CDC or FDA. Individual health care providers are the most-trusted source for health information across partisanship.

Across demographic groups – including age, gender, race and ethnicity, and education – health care providers remain the most trusted source of health information. For other health information sources, trust can vary by different groups. White adults and those with a college degree are more likely to express trust in their doctor or health care provider, which may reflect health care access issues. Trust in the CDC and state government officials also differs by education, with college-educated adults more likely to express trust in these sources. White adults are more likely than their peers to express trust in Secretary Kennedy and President Trump for health information.

Most of the public lacks confidence in agencies like the CDC or FDA to carry out many of their core responsibilities. While Democrats are somewhat more likely than Republicans to have at least “some confidence” in government health agencies to ensure vaccine safety and effectiveness and make recommendations about the childhood vaccine schedule, fewer than half across partisans have confidence in these agencies to make decisions based on science. For more information, see KFF’s January 2026 Tracking Poll on Health Information and Trust.

Less than half of the public and partisans express at least “some confidence” in the CDC, FDA, or EPA to act independently without outside interference. Democrats are somewhat more likely to say they have confidence in the CDC to act independently, with almost half expressing confidence. On the other hand, four in ten or fewer adults and partisans express confidence in the independence of the FDA or the EPA. For more information, see KFF’s April 2026 Health Tracking Poll.

At the onset of the COVID-19 pandemic, there were high levels of bipartisan trust in information about the new virus from the U.S. Centers for Disease Control and Prevention (CDC). Trust in the agency for information about COVID-19 vaccines, and vaccines more generally, subsequently declined amid widening partisan divisions and large drops in Republican trust. Democratic trust in the agency has since declined significantly following President Trump’s reelection and the confirmation of Robert F. Kennedy Jr. as HHS Secretary. Amid these partisan shifts, half of the public now express trust in the CDC for reliable vaccine information. Keep scrolling to see trends among the public and partisans.  

KFF polling has found trust in vaccine information from other health agencies and officials has also declined amid partisan divisions since 2020, including for the U.S. Food and Drug Administration (FDA), state government officials, and local public health departments. 

Among parents of children under age 18, pediatricians are the most trusted source of reliable vaccine information. Smaller shares, but still majorities, also trust their local public health department, the CDC, and the FDA. Over half of parents trust their friends and family for vaccine information, while far fewer express trust in Robert F. Kennedy Jr., pharmaceutical companies, or health and wellness influencers. As with the public overall, partisanship plays a role in who parents trust for vaccine information. For more information, see the KFF/Washington Post Survey of Parents.

Among parents, Secretary Kennedy garners trust on vaccines from a majority of Republican supporters of the Make America Great Again, or MAGA, movement (18% of all parents) and supporters of the Make America Healthy Again, or MAHA, movement (38% of all parents). While slim majorities of these MAGA and MAHA parents trust Kennedy for vaccine information, larger shares express trust in their child’s pediatrician.

About three in ten adults say they use social media to find health information and advice “at least monthly,” including larger shares of younger adults, Black and Hispanic adults, lower income adults, and those with lower educational attainment. For more information see KFF’s June 2026 Tracking Poll on Health Information and Trust.

About one-third of adults who use social media for health information say a “major reason” they turned to social media for health advice was because they wanted to learn from people with similar experiences or because they wanted immediate information or support. About one in six users cite difficulty accessing or affording health care as a major reason.  

Similar shares of adults who use social media for health information or use AI chatbots for health information cite difficulties accessing or affording health care as major reasons they turned to these tools for health advice. These reasons are more commonly cited among lower income social media and AI users. For additional information on use of AI for health information, see AI and Health Information section below.

While fewer than half of the public report actively using social media at least monthly to find health information and advice, larger shares report being exposed to such information in the past month, with majorities saying they have recently seen content related to weight loss, diet, or nutrition and mental health.

While four in ten social media users say they regularly get information about news and politics from social media influencers, far fewer (15%) say they turn to influencers for health information and advice. Younger adults, Black adults, and more frequent social media users are more likely than their peers to say they rely on influencers for health information. For more information on the relative impact of influencers on the public and health policy debates, see KFF CEO Drew Altman’s column.

Across different social media platforms, fewer than half of users say they find at least “some” of the health information they see on these platforms to be trustworthy. Younger users tend to be more trusting than older users of health content on certain platforms including TikTok, YouTube, Instagram, and Reddit.

About a third (32%) of the public reports turning to AI chatbots for health information and advice in the past year – rivaling social media as a health information source, but less common than reliance on health care providers or internet search engines (where they may be encountering AI generated results, even if they are not looking for them). The share of adults using AI for health information includes three in ten who say they’ve used these chatbots in the past year for information or advice about their physical health, and one in six who’ve used them for mental health information or advice. For more information, see KFF’s March 2026 Tracking Poll on Health Information and Trust.

Larger shares of younger adults report turning to AI for either physical health or mental health information in the past year. When it comes to mental health advice, uninsured adults and Black and Hispanic adults are more likely than insured adults and White adults to have turned to AI.

People report using AI for either physical health or mental health information in a variety of ways, most commonly to look up symptoms or general information about health conditions. Fewer say they used AI to help make decisions about whether to seek medical care for either physical or mental health concerns.

The most common reason people cite for turning to AI for health advice is wanting quick or immediate support. Many also cite wanting to look up information before seeing a provider or feeling more comfortable looking up health questions privately. One in five cite health care access or affordability issues as major reasons for turning to AI for health questions, including larger shares of younger adults and those with lower household incomes

Among the public overall, few adults say they trust AI tools to provide reliable information about health, but most adults who have used AI for health information and advice say they trust these chatbots to provide reliable health information.

Exposure to health misinformation is often widespread, but relatively small shares of the public express certainty that many false or unproven claims are true. In fact, at least half of the public fall in a “malleable middle,” saying these claims are either “probably true” or “probably false.” The public’s uncertainty around false or unproven health claims related to COVID-19 , vaccines , measles  and the purported causal link between Tylenol and autism presents an opportunity for interventions to clear up confusion and deliver accurate information.

KFF polls have measured exposure to a wide array of false, misleading, and unproven health claims since 2023. Exposure varies widely depending on the topic and prominence of news coverage of the claim. The most widely heard of those tested in KFF polls is that taking Tylenol during pregnancy increases the risk of a child developing autism, a claim cited by President Trump in a widely covered September 2025 press conference.

Across an array of false or unproven health claims measured in KFF surveys, few adults are certain these claims are “definitely true” while much larger shares say they are “definitely false.” For most claims, at least half express uncertainty, falling into the malleable middle and saying the claims are either “probably true” or “probably false.” Seven recent false or unproven health claims measured in 2026 and 2025 KFF surveys are shown below.

While KFF polling has consistently found that much of the public falls in the “malleable middle” when it comes to a wide array of false health claims, there are nuances within this group that can be examined by looking at patterns of belief across multiple myths. KFF’s June 2026 Tracking Poll on Health Information and Trust identified five groups based off patterns of belief across four common vaccine myths:

KFF polling has found partisanship and education play a substantial role in belief of false or unproven health claims about vaccines, COVID-19 and measles. Republicans and adults without a college degree are consistently more likely than Democrats and college educated adults, respectively, to believe or lean towards believing vaccine-related myths. For more information, see KFF's June 2026 Tracking Poll on Health Information and Trust.

Beyond partisanship and education, belief in common vaccine myths sometimes varies by age and race and ethnicity. Larger shares of adults ages 30-49 compared to older adults say false claims about vaccines are either definitely or probably true, as do Black adults compared to White adults. Hispanic adults are more likely than White adults to endorse two false claims about the measles vaccines. These differences show that susceptibility to health misinformation among some groups can vary depending on the topic, which may reflect different information channels relied upon by these groups (see social media and news sources sections for more information).

Adults who frequently use social media or artificial intelligence (AI) tools for health information are more likely to say several false claims about vaccines are definitely or probably true, as are those who lack a trusted health care provider compared to those who have a provider they trust to answer questions about their health.

KFF polling has sought to examine the public’s exposure to and belief in a wide array of false or unproven health claims. Many of the false or unproven claims measured in KFF surveys have been amplified by or directly made by government officials, while others have been more nebulously shared and spread in public media over the years. Below is a list of sources to document these claims’ inaccuracy.

Most U.S. adults, including majorities across partisans, express confidence in the safety of many routine vaccines for children, including MMR, polio, and hepatitis B. Similarly, large majorities of adults ages 50 and over are confident that vaccines for pneumonia and shingles are safe. Views on the safety of COVID-19 and flu vaccines for both adults and children are more divided, with large shares of Democrats expressing confidence compared with smaller shares of Republicans. For more information, see KFF’s, September 2026, January 2026 and April 2025 Tracking Polls on Health Information and Trust.

In summer 2025, large majorities of parents expressed confidence in the safety of childhood vaccines for polio and measles, mumps, and rubella (MMR), but parents’ views on the safety of flu and COVID-19 vaccines were more polarized. About two-thirds of parents say the flu vaccines are safe for children, while fewer than half say the same about COVID-19 vaccines, with divisions along partisan lines. Beyond partisanship, parents who support the Make America Healthy Again (MAHA) movement (38% of parents), Black parents and parents under age 35 are less likely than their peers to be confident that many routine vaccines are safe for children. For more information, see the KFF/Washington Post Survey of Parents.

Most parents report keeping their children up to date on childhood vaccines, but about one in six say they have ever skipped or delayed at least one childhood vaccine for any of their children (excluding seasonal vaccines like flu and COVID-19). Despite strong uptake, many parents express skepticism towards vaccine safety testing and the number of vaccines recommended by the CDC (this survey was fielded prior to recent changes to the childhood vaccine schedule announced by HHS in January 2026). Younger parents and those who identify as Republicans are more likely than their counterparts to endorse vaccine-skeptical attitudes and to report skipping vaccines for their own children. For more information, see the KFF/Washington Post Survey of Parents.

Parents who skip or delay recommended vaccines for their children are about twice as likely as parents who keep their children up to date on vaccines to believe or lean toward believing false claims about the measles and COVID-19 vaccines, underscoring how false health claims may shape parents’ decisions. For more information, see KFF's June 2026 Tracking Poll on Health Information and Trust.

COVID-19 vaccines and some other vaccines currently under development rely on a vaccine technology known as messenger-RNA (mRNA), which has long been the subject of misinformation. While few adults view mRNA technology as unsafe, the technology remains obscure to much of the public, with about half saying they don’t know enough to say. For more information, see KFF’s April 2025 Tracking Poll on Health Information and Trust.
