A new Reuters/Ipsos poll shows declining trust in measles vaccines among Americans, with only 76% now believing they are safe for children compared to 84% in May 2020. This drop is particularly significant among Republican voters and coincides with recent efforts by President Donald Trump's administration to reduce the number of childhood vaccinations. The country is experiencing its worst measles outbreaks since 1991, with over 3,000 confirmed cases and three deaths reported in Pennsylvania alone this year.

Story summary
A new Reuters/Ipsos poll conducted over four days and completed on September 14, revealed that 76% of Americans now believe vaccines for measles, mumps, and rubella are safe for children, down from 84% in a similar survey in May 2020. The decline is most notable among Republicans due to some party figures' efforts to minimize the importance of vaccines. Meanwhile, President Donald Trump signed an executive order aiming to reduce recommended childhood immunizations from 17 to 11, echoing his health official's stance: Robert F. Kennedy Jr., a longtime anti-vaccine activist before being appointed by Trump. This shift is concerning as measles cases are surging in states like Pennsylvania, Utah, and South Carolina, with the U.S. at risk of losing its status as a country that eliminated measles decades ago due to ongoing domestic transmission.
