Washington is weighing changes to long-standing childhood vaccines — and Florida parents are paying close attention. In conversations across the state, one thing comes up again and again: parents want the freedom to make informed health decisions for their kids.

For some families, that means opting not to vaccinate their children. But for most families, that freedom means getting routine childhood vaccines. Nearly nine in 10 Florida kindergarteners received routine childhood immunizations for the 2024-2025 school year.

Parents may differ in their decisions, but they agree that federal agencies shouldn’t throw up roadblocks or restrict families’ voluntary access to vaccines. Yet that’s exactly what some proposals recently floated in Washington would do — at the very moment preventable diseases are resurfacing.

Measles, once nearly eliminated in the United States, is re-emerging. Florida is in the midst of an outbreak, and wastewater testing suggests the virus may be circulating more widely than the official numbers show. Nationally, the United States could soon lose its measles elimination status for the first time in 25 years.

A bunch of new ideas have been floated inside the beltway, ranging from changing what ingredients go into vaccines to altering which diseases have stand-alone vaccines or are combined into a single shot, and even using other countries’ vaccine schedules as a standard for American families.

This adds up to mixed messages about what is safe for kids, leading to general confusion for parents. People should be able to trust that Washington “experts” will rebuild trust in health care and not rush through an agenda. We need to make sure people have access to the tried-and-true routine vaccines they want, without making them harder to find or more expensive.

Florida Republicans have always stood for parental rights and medical freedom. As the Legislative Director for the Republican Liberty Caucus of Florida, I’ve worked to defend those principles. That means no family should be forced to vaccinate, but it also means families who choose vaccines deserve clear, consistent federal guidance — and not increased costs to get them.

Members of our congressional delegation have long understood that balance. Congressman Neal Dunn, a physician, has emphasized that medical decisions belong between families and their doctors — not dictated in federal committee rooms.

That principle is being challenged now. When Washington complicates access to long-standing childhood vaccines, Florida parents bear the fallout: disrupted classrooms, last-minute childcare scrambles, and pediatric clinics stretched thin. We’ve lived through that kind of instability before. No family wants a repeat.

Protecting freedom means protecting options. And right now, Florida families need their Republican leaders to stand firmly against federal policies that would make it more confusing — and more difficult — for parents to decide how to best care for their children.
