Interactive Tool Visualizes Vaccine vs. Disease Risk Comparisons
University of Minnesota's tool helps contextualize vaccine risks against disease threats.
1Addressing Vaccine Confusion
The 'What's the Risk?' tool launched in August 2023 to combat widespread vaccine misinformation. Developed by the University of Minnesota's CIDRAP and Unbiased Science podcast, it visually compares complication rates between vaccines and the diseases they prevent. Currently covers measles/MMR and RSV vaccines, with plans to expand. The tool specifically targets the 'malleable middle' - 50% of Americans uncertain about vaccine safety according to KFF research.
2How the Visualization Works
The interface displays two light gray boxes representing 100,000 people each. Colored squares within show risk frequency (size) and severity (color - red for serious outcomes). Users can compare different age groups, though developers caution comparisons are most accurate within the same demographic. All data shows annual rates, with everyday risks (like car accidents) converted from lifetime statistics for accurate comparison.
3Data Integrity Measures
Every statistic comes directly from national surveillance systems or peer-reviewed studies, never secondary sources. The team matched vaccine/disease data by age group and population where possible, clearly labeling mismatches. Co-creator Jessica Steier emphasizes: 'Every figure must be from public, citable sources and measured identically to its comparison point.' Sources are linked for verification.
4Understanding Risk Dimensions
The tool educates users that proper risk assessment requires three elements: likelihood of outcome, potential severity, and baseline comparisons. This addresses what Steier calls 'numbness' to statistics - where '1 in 10,000' and '1 in 1,000,000' both register simply as 'rare.' The visualization makes these orders of magnitude difference immediately apparent through relative square sizes.
5Personal Risk Factors
While displaying population averages, the tool reminds users that individual risk depends on age, health status, and lifestyle. Future versions may incorporate ZIP code-level vaccination rates to show community protection effects. Currently, users can adjust views between 100,000 and 50,000 population scales, and toggle grid/layout displays for different perspectives on the same data.
6Planned Enhancements
Version 1.0 will expand to include more vaccines/diseases and everyday risk comparisons (like drowning or lightning strikes) that help contextualize unfamiliar medical risks. Most anticipated feature: vaccine coverage visualization showing how community vaccination rates directly impact disease exposure likelihood. This may include interactive sliders to simulate different herd immunity scenarios.
7Public Health Communication
The tool represents an innovation in science communication, translating complex epidemiological data into accessible formats. Steier notes: 'We're fighting number numbness - people hear scary statistics constantly without understanding scale.' By making relative risks visually apparent, the tool helps users develop critical thinking habits about risk comparisons.
8Why This Matters
With vaccine hesitancy remaining a top-10 global health threat (WHO), tools like this provide evidence-based counterarguments to misinformation. The visualization demonstrates how vaccines reduce disease risk by orders of magnitude while putting rare side effects in proper context. Future community-level data could strengthen the case for vaccination as a collective responsibility.
