In the ongoing debate surrounding childhood vaccination mandates, new research from the Annenberg Public Policy Center (APPC) sheds light on evolving public attitudes toward the Measles, Mumps, and Rubella (MMR) vaccine requirements for school attendance in the United States. This latest survey data, collected in April 2025, reveals that public support for mandatory MMR vaccinations for children entering public schools has reached an impressive 70%, marking a significant increase compared to similar measurements taken in previous years. This uptick in support highlights a noteworthy shift in the evolving landscape of public health policy and parental attitudes toward vaccination.
The Annenberg Science and Public Health (ASAPH) survey, which canvassed a nationally representative sample of 1,653 U.S. adults, examined viewpoints on the complex balance between individual parental choice and public health imperatives. Participants were asked to weigh their stance on whether healthy children should be required to receive the MMR vaccine to attend public schools, emphasizing the communal risks associated with unvaccinated populations. The overwhelming majority favored the mandate, with 70% acknowledging the importance of vaccination to protect not only individual children but also the broader school community from potential outbreaks of measles and associated viral infections.
This trend contrasts with a more ambivalent, yet still majority, stance reported in August 2023 when 63% supported mandatory vaccination for school attendance. This notable increase underscores the impact of ongoing public discourse, epidemiological developments, and potential outbreaks on shifting public opinion. At the same time, only 18% of respondents in the latest survey indicated a preference for parental autonomy over school vaccination mandates, even acknowledging the public health risks posed by such choices.
This public sentiment emerges amid a broader policy debate exemplified by contrasting governmental voices. For instance, Robert F. Kennedy Jr., U.S. Secretary of Health and Human Services as of 2025, expressed support for the efficacy of the MMR vaccine via social media but maintained opposition to government-imposed vaccine mandates during a televised interview. This dichotomy reflects the tension between recognizing the scientific consensus on vaccine effectiveness and respecting individual freedoms in public health policymaking.
Further complicating the landscape is the Trump administration’s Make America Healthy Again (MAHA) Commission report delivered in September 2024. The MAHA report advocated for a reevaluation of current childhood vaccine schedules and mandates, calling for enhanced transparency to inform parents comprehensively about vaccine risks and benefits. The report notably raised concerns about a potential link between vaccine use and rising rates of chronic childhood diseases, a contentious point that diverges from the mainstream scientific consensus yet contributes to shaping public dialogue.
The methodological rigor of the APPC’s ASAPH survey strengthens the credibility of these recent findings. Conducted by SSRS, an independent market research firm, the survey represents the 24th wave of data collection from an ongoing nationally representative panel initiated in 2021 and supplemented by replenishment samples to offset attrition. The April 15-28, 2025, wave surveyed its 1,653 participants with a margin of error of ±3.4 percentage points at the 95% confidence level, ensuring statistically robust insights into public opinion trends.
From an epidemiological perspective, the significant support for MMR vaccination mandates is particularly important given the highly contagious nature of measles, an acute viral illness caused by the measles virus within the Paramyxoviridae family. Measles can cause serious complications, including pneumonia, encephalitis, and death, particularly in vulnerable populations such as infants and immunocompromised individuals. Vaccination not only protects individual recipients but also contributes to herd immunity, reducing the likelihood of outbreaks in the community and safeguarding those unable to be vaccinated.
The mumps and rubella components of the MMR vaccine further extend the public health benefits by preventing outbreaks of mumps, which can cause painful swelling of salivary glands and may lead to complications such as meningitis, orchitis, and hearing loss, and rubella, which is especially dangerous for pregnant women due to its teratogenic effects leading to congenital rubella syndrome. The combination vaccine’s widespread use has been a cornerstone of public health efforts to control these viral diseases in the U.S. and globally.
The APPC’s findings align with a broader national health communication effort to engage the public on the importance of evidence-based vaccine policies. The data reveal a growing acceptance of vaccine mandates despite persistent misinformation and vaccine hesitancy movements. Importantly, the survey also reflects nuanced public attitudes favoring discrete opt-out options for vaccination under certain circumstances, such as medical contraindications, though widespread opt-outs that undermine herd immunity remain a continued concern.
These insights arrive amidst a backdrop of numerous other public health challenges tackled by the Annenberg Public Policy Center’s survey panel over the past four years, encompassing COVID-19, flu, RSV, and other pressing infectious diseases. Their longitudinal surveillance affords a comprehensive perspective on how public knowledge and beliefs evolve in response to emerging health threats and policy interventions.
The APPC team members—research analyst Laura A. Gibson, director Patrick E. Jamieson, managing director Ken Winneg, and director Kathleen Hall Jamieson—continue to provide invaluable expertise in survey design and interpretation. Their work advances public understanding of vaccine-related health policy, contributing to informed decision-making by policymakers, healthcare professionals, and the public alike.
As measles outbreaks continue to pose significant risks in under-vaccinated communities, these survey results carry urgent implications for policymakers. Strong public support for MMR vaccine mandates should embolden efforts to maintain and strengthen school-entry vaccination laws, which remain one of the most effective strategies to prevent outbreak resurgence. In parallel, addressing parental concerns through transparent communication and education remains essential to mitigate vaccine hesitancy.
Ultimately, the ASAPH survey confirms that while vaccine hesitancy persists within segments of the population, the mainstream American public increasingly prioritizes collective health protection through vaccination mandates. The data underscore the dynamic interplay between scientific evidence, public attitudes, and political discourse, highlighting the critical role of rigorous social science research in guiding health policy.
