Florida moves to drop four school vaccine mandates as measles cases climb

Florida’s public health system has maintained strict vaccination rules for decades, a framework designed to keep preventable diseases from spreading in schools and childcare centers. That framework is now under review.

The Florida Department of Health held a hearing in October 2026 to consider removing four specific vaccine requirements for school and childcare entry: Haemophilus influenzae type b (Hib), chickenpox, pneumococcal, and hepatitis B. The proposal does not eliminate the vaccines themselves, but it would remove the mandate that keeps coverage rates high.

The timeline for these requirements stretches back several decades. The hepatitis B vaccine entered use in the U.S. in 1982, followed by the Hib vaccine in the late 1980s. Chickenpox vaccination began in 1995, and the pneumococcal vaccine for children arrived in 2000. These dates align with the period when many current parents were growing up and beginning to see the effects of widespread vaccination.

Before these vaccines, the disease burden was heavy. In the early 1980s, 20,000 invasive Hib infections occurred among American children under five, with 12,000 cases of meningitis. Between 3% and 6% of those children died, and 15% to 30% of survivors suffered deafness or brain damage. By 2023, the United States reported only 13 Hib cases in that age group, though the number rose to 28 in 2026.

Chickenpox presented a different challenge. By the early 1990s, the U.S. recorded more than 4 million cases annually. While often manageable in children, the disease led to 10,500 to 13,500 hospitalizations and 100 to 150 deaths each year. Since vaccination began, deaths from chickenpox in people under 20 have virtually disappeared. Pneumococcal disease caused about 17,000 invasive infections in children under five before the 2000 vaccine introduction, including 700 cases of meningitis and 200 deaths. Hepatitis B infected an estimated 20,000 American children annually before the 1982 vaccine, with a 90% chance of chronic infection in infants.

The removal of these mandates would weaken herd immunity. When vaccination rates fall, diseases can spread among susceptible children, including those too young for full vaccination or those with medical conditions that prevent adequate protection. Epidemiologist Katrine L. Wallace, an assistant professor at the University of Illinois Chicago, noted that the luxury of forgetting these diseases could lead to a generation of children who are not vaccinated against them.

Florida is currently facing a resurgence of measles, a disease eliminated nationally in 2000. An outbreak at Ave Maria University outside Naples infected at least 62 people. As of October 17, 2026, the state reported 162 cases. This outbreak is occurring while only 88.9% of Florida kindergartners received the measles, mumps, and rubella (MMR) vaccine during the 2025-26 school year. That rate is below the U.S. national average of 92.4% and the recommended 95% threshold for herd immunity.

Tracking these diseases has become more difficult. The Florida Department of Health removed county-level disease data from its website in May 2026. Although the data has since been replaced, there is no current measles dashboard for public tracking. The department’s 2026 counts have been delayed, and public tracking systems currently disagree on the statewide total. Florida’s historical records for some diseases, such as chickenpox, are also incomplete, as the state did not track it until late 2006.

The hearing in October marked the first major step in the review process. The department will continue to gather input before making a final decision on the four vaccine requirements. The outcome will determine whether these specific protections remain in place for the upcoming school year.
