Florida weighs dropping four school vaccine mandates amid measles outbreak

The proposal would not eliminate the vaccines or mean that every family would stop using them. It would weaken one of the policies designed to maintain high vaccination coverage.

The proposal comes as Florida has reported 162 measles cases this year, according to data available as of October 17. Measles was eliminated nationally in 2000, meaning sustained endemic transmission had been interrupted, but imported infections can trigger outbreaks when they reach undervaccinated communities. An outbreak at Ave Maria University outside Naples infected at least 62 people. Meanwhile, only 88.9% of Florida kindergartners received the measles, mumps and rubella (MMR) vaccine in the 2025–26 school year, below the national average of 92.4% and the recommended 95% threshold for creating herd immunity.

Epidemiologist Katrine L. Wallace of the University of Illinois Chicago, writing for The Conversation, warned that if fewer children are vaccinated as a result, risks would extend beyond the families making that choice. She noted that before vaccines became widespread, Hib caused 20,000 invasive infections and 12,000 cases of meningitis annually in American children under five. Chickenpox led to more than 10,000 hospitalisations each year before vaccination began in 1995. After Hib conjugate vaccines were introduced in the late 1980s, cases among young children declined by 99%. Wallace wrote that an entire generation of parents has been spared seeing severe complications, describing this as an achievement of vaccination and a reminder of what can be forgotten when prevention works.

The Florida Department of Health currently has no measles dashboard to track cases in the state, and its 2026 counts have often been delayed, making it difficult to know current measles rates.
