KFF Poll Finds CDC Trust at Five-Year Low With Broad Disapproval of RFK Jr.

Following vaccine policy upheaval, trust has shifted to clinicians, with professional groups eclipsing federal agencies on vaccines.

Most adults in the US say they disapprove of the way Robert F. Kennedy Jr. is handling his role as HHS secretary, especially vaccine policy, a KFF poll found.
WASHINGTON, DC - SEPTEMBER 22: U.S. President Donald Trump answers questions after making an announcement on “significant medical and scientific findings for America’s children” in the Roosevelt Room of the White House on September 22, 2025 in Washington, DC. Federal health officials suggested a link between the use of acetaminophen during pregnancy as a risk for autism, although many health agencies have noted inconclusive results in the research.

Polls indicate a partisan divide between those who believe the Trump administration claim that Tylenol use can cause autism in children.

Overview

  • Only half of U.S. adults now trust the CDC to provide reliable vaccine information, down from 57% in July and 63% in September 2023, according to KFF.
  • Majorities disapprove of Robert F. Kennedy Jr.’s performance and his vaccine policy approach after sweeping changes that replaced ACIP members, narrowed COVID-19 recommendations and ousted the CDC director.
  • Just 4% say the claim that Tylenol use in pregnancy causes autism is definitely true, 35% call it definitely false, and most remain unsure, with Republican women far more likely to lean toward believing it.
  • Doctors remain the most trusted source for vaccine information (more than 80% express trust), and roughly two-thirds trust the AAP and AMA, which have published guidance that departs from federal recommendations and has been adopted by some states.
  • KFF surveyed about 1,300 adults from September 23 to 29, beginning the day after a White House briefing where President Donald Trump and Kennedy promoted concerns about acetaminophen; the margin of error is plus or minus 3 percentage points.
