Americans’ trust in the CDC has plummeted since 2025, new poll finds

A mere 12 percent of Americans say they trust the U.S. Centers for Disease Control and Prevention’s recommendations “a great deal”

Americans’ trust in the U.S. Centers for Disease Control and Prevention has nose-dived during President Donald Trump’s second term, a new poll from Harvard University and the de Beaumont Foundation found. Just 50 percent of respondents said they trust health recommendations from the CDC at all—a steep drop from 77 percent who said they trusted the CDC in 2025.

Since last year’s poll was conducted, the Trump administration has overhauled U.S. health and science agencies. Secretary of Health and Human Services Robert F. Kennedy, Jr., has fired longtime agency vaccine scientists , while multiple senior leadership figures at the CDC, as well as other health agencies, have resigned or accused Kennedy of pushing them out. The CDC has also stopped coordinating closely with international public health agencies, such as the World Health Organization , and sought to reduce the number of recommended vaccines for children. And the Department of Health and Human Services has altered the U.S. food pyramid to encourage Americans to eat more red meat. (Some of these moves have been challenged in court .)

All of these changes have been criticized by public health experts, researchers and medical and science associations as endangering the health of Americans, especially children.

The new poll included about 2,200 adults and was conducted between March 19 and April 1, 2026. Democrats and Independents have particularly lost faith in the CDC: just 34 percent of Democrats and 47 percent of Independents said they “somewhat” trust the agency’s recommendations, down from 92 percent and 77 percent in 2025, respectively. Meanwhile about 67 percent of Republicans said they trust the agency—up from 63 percent in 2025.

Other wings of HHS also saw low levels of trust in 2026: Just 53 percent of poll respondents trust the U.S. Food and Drug Administration and the National Institutes of Health to improve health. HHS did not immediately respond to a request for comment from Scientific American .
