Analysis
Peter Hotez did state in the 2023 NPR interview that childhood vaccination rates have dropped sharply in some states and blamed disinformation alone. CDC data shows modest declines in certain states but not a "collapse" of rates, which remain above 85% for most. Research indicates that while misinformation fuels hesitancy, access issues (e.g., insurance gaps, clinic shortages) also contribute, especially in underserved areas. Therefore the statement overstates the magnitude of the drop and attributes it solely to disinformation, making it misleading.
Background
Measles outbreaks have risen in the U.S. in recent years, prompting concern among public health officials. The CDC reports that national MMR coverage for kindergarteners was 92% in 2022, with some states below 80%, but the overall trend is a slight decline rather than a collapse. Studies identify both misinformation and structural barriers as drivers of vaccine hesitancy.
Verdict summary
Hotez’s claim exaggerates the decline in vaccination rates and oversimplifies the causes.
