Florida gubernatorial nominee Byron Donalds pointed to illegal immigration under the Biden administration, not low vaccination rates, as the cause of measles outbreaks, refusing to urge Florida parents to vaccinate their children when pressed on live television.
Donalds, a Republican congressman representing southwest Florida, appeared on CBS's "Face the Nation" on Sunday and faced direct questioning from host Margaret Brennan about the state's lagging immunization numbers. Brennan noted that nearly all of Florida falls below the 95 percent immunization rate public health officials consider necessary for measles herd immunity. She asked Donalds whether his message to Florida parents was simple: get your kids vaccinated.
He said no. Instead, Donalds told Brennan the real driver was the Biden administration's failure to secure the southern border, which he said allowed more than 10 million people to enter the country without following any vaccination schedule.
When Brennan asked what evidence he had, Donalds cited geography. He pointed to outbreaks in El Paso, Texas, and in his own backyard in southwest Florida, areas he said have seen large numbers of illegal immigrants arrive without basic immunizations.
"Margaret, we've seen the outbreaks in El Paso, Texas, in southwest Florida, where I live, and many other parts where you know that you have a situation, people have come into the country illegally, have not had that vaccination schedule. And not the ones today on young kids, that parents do have concerns about. I'm talking about previous ones, where people weren't even getting the measles vaccine or mumps and rubella."
Donalds drew a line between the pre-Biden period and the present. He argued that before Biden took office, "our borders were basically secure," and that the mass influx that followed disrupted public health norms that had kept diseases like measles in check.
Brennan tried to pin him down. "So, you want them to be vaccinated?" she asked. Donalds did not take the opening to endorse vaccination broadly. Instead he returned to border enforcement.
"So, the key thing is you, number one, you've got to control immigration into your country. You can't have an entire segment of people, more than 10 million, come into your country without that vaccination schedule. That's how you end up having some of these outbreaks."
After addressing immigration, Donalds pivoted sharply to healthcare costs, a move that kept him from ever directly answering whether Florida parents should vaccinate their children against measles. He called the Affordable Care Act's regulatory framework a driver of rising costs and said that issue would be his focus as governor.
"I think that's much more of a constructive conversation about costs and health care and trying to stabilize prices than just simply vaccinations."
Brennan acknowledged the cost concern but pushed back, noting it did not address coverage or how families actually pay for care. "But in terms of keeping people healthy, nearly all of Florida is below the 95% immunization rate for herd immunity for measles," she said, steering the exchange back to the vaccination question Donalds had sidestepped.
By the end of the exchange, Brennan offered a summary of his position: "So, you want vaccinated immigrants." Donalds corrected her, but not in the direction of endorsing vaccines.
"Actually, I want, I just want legal immigrants. To be clear, I just want legal immigration with assimilation."
It was a clean closing line for a candidate running in a Republican primary. But it left the vaccination question exactly where it started: unanswered.
Brennan's claim that nearly all of Florida sits below the 95 percent herd immunity threshold for measles went unchallenged by Donalds during the broadcast. She did not cite a specific source for the figure on air, and the interview transcript does not include one. Donalds neither disputed the number nor addressed what it might mean for Florida families, he treated it as beside the point.
That framing carries political logic. For conservative voters in a gubernatorial primary, border security ranks well above public health mandates as a motivating issue. Donalds made a calculation: linking measles to illegal immigration lets him talk about a problem his base already cares about while avoiding a topic, childhood vaccination, that divides Republican voters.
Whether the connection he drew holds up under scrutiny is a separate matter. Donalds offered no case counts, no epidemiological data, and no public health agency findings to support his claim that illegal immigration caused the outbreaks he referenced. He relied on the geographic overlap between outbreak locations and areas with high illegal immigrant populations. That overlap may be real, but geographic coincidence is not causation, and Donalds did not bridge the gap.
Donalds is not wrong that uncontrolled immigration creates public health risks. People entering the country outside lawful channels do bypass the medical screening and vaccination requirements that legal immigrants must meet. More than 10 million illegal border crossings during the Biden years, a figure Donalds cited and that aligns with widely reported federal encounter data, represent a population whose health status the government largely did not track.
That is a legitimate concern, and it deserves serious policy attention. But using it to dodge a straightforward question about whether Florida parents should vaccinate their own children against measles is a different move. Brennan asked a yes-or-no question. Donalds gave a border-security answer. The two issues are not mutually exclusive. A candidate can support secure borders and tell parents that the measles vaccine works.
Donalds chose not to. That choice tells voters something about how he plans to govern, and what questions he considers worth answering directly.
Accountability means giving straight answers, even when the question comes from a network anchor you don't trust, and especially when the people waiting on the answer are the parents and kids in your own state.
