Americans' trust in measles vaccines falls to 76%, posing crisis risk

A Reuters/Ipsos poll shows vaccine confidence eroded amid Trump policies and RFK Jr.'s anti-vaccine stance, as measles cases hit 35-year high.

What to know

  • Vaccine confidence among Americans fell 8 points to 76% since May 2020, with steepest declines among Republicans, amid Trump's executive order cutting childhood vaccine schedule and RFK Jr.'s anti-vaccine advocacy.
  • The U.S. is experiencing its worst measles outbreak in 35 years with 3,000+ cases and three deaths in Pennsylvania; vaccination coverage at 92.5% has dropped below the 95% herd immunity threshold.
  • Only 19% of Americans approve of Trump's measles response; voters favor Democrats 45%-25% on infectious disease handling, though measles ranks below cost of living as voter concern.
  • The U.S. is expected to lose its measles elimination status in 2026 if sustained transmission continues, a historic reversal for a nation that eradicated the disease decades ago.
