Repealing Florida’s school MMR mandate could spark the largest US measles epidemic in nearly 50 years
The University of Maryland reports that its researchers modeled Florida’s proposed policy change and found that falling childhood vaccination rates would increase the risk of a large outbreak.
TLDR
The University of Maryland reports that researchers modeled the proposed repeal of Florida’s school-entry MMR requirement using data from a 2025 Texas outbreak and Florida vaccination coverage. Their simulations found that further declines in childhood vaccination would raise the risk of a large measles epidemic. The researchers say adult catch-up shots and measures such as masking could help, but would not make up for lower childhood MMR coverage.
