Survey Finds Nearly 5-1 Majority of Americans Believe Benefits of MMR Vaccine Outweigh Risks for Children

A recent survey conducted by the Annenberg Public Policy Center reveals that nearly five times as many Americans believe the benefits of the measles, mumps, and rubella (MMR) vaccine for children outweigh its risks. Despite ongoing measles outbreaks in the United States, the study shows strong public support for vaccination, with 83% of respondents emphasizing the vaccine's advantages.

The survey highlights that the current measles resurgence, with over a thousand confirmed cases in 2025 and several deaths reported by the CDC, underscores the importance of vaccination. Although many Americans understand how measles spreads—such as through coughing, sneezing, or touching contaminated surfaces—their awareness of the potential complications remains limited. For instance, less than half correctly identify that measles in pregnant women can cause serious issues like early delivery or low birth weight.

The data also indicate that most Americans recognize the protective efficacy of the two-dose MMR vaccination schedule, which is about 97% effective when administered properly. However, vaccine hesitancy persists; while two-thirds of Americans reject the debunked link between MMR and autism, a small but concerning 14% still believe such a connection exists—an increase since 2021.

Furthermore, public opinion favors vaccine mandates for schoolchildren, with 70% supporting required vaccinations to attend public schools, compared to 18% favoring parental choice. Knowledge gaps about measles transmission and risks during pregnancy highlight the need for enhanced public health education, especially regarding the importance of vaccination before pregnancy.

Overall, the survey emphasizes widespread support for the MMR vaccine and the importance of continued efforts to promote vaccination and dispel misconceptions, vital steps in controlling and preventing measles outbreaks in the United States.
