Poll Reveals Rising Misinformation on Measles Vaccine Among Americans

As measles cases surge to their highest levels in years across the U.S., with outbreaks concentrated in Texas and reported in over half the states, misinformation about the measles, mumps, and rubella (MMR) vaccine is spreading widely. Polls show that nearly two-thirds of adults have heard the false claim that the MMR vaccine causes autism, and a growing number are exposed to other myths, such as the vaccine being more dangerous than the disease and vitamin A preventing infection. While most Americans maintain confidence in the vaccine's safety, a substantial 'malleable middle' expresses uncertainty about these falsehoods, with around a quarter incorrectly believing or doubting the established science. Misinformation is especially prevalent among Republicans and Hispanic adults, and partisanship sharply influences both awareness of the outbreak and perceptions of vaccine safety. The amplification of these myths by high-profile officials, including Health and Human Services Secretary Robert F. Kennedy Jr., has contributed to their reach, raising concerns about vaccination rates as the outbreak continues. Experts emphasize the importance of accurate information to counteract the growing tide of vaccine skepticism.
