Federal Response
The CDC has deployed its Epidemic Intelligence Service (EIS) officers to assist local health authorities in managing the outbreak. HHS Secretary Robert F. Kennedy Jr. told Fox News that the CDC’s rapid response team had treated 108 patients in the first 48 hours of arriving in Texas.
“The measles outbreak in Texas is a call to action for all of us to reaffirm our commitment to public health,” Kennedy said in a statement. “Under my leadership, HHS is and will always be committed to radical transparency to regain the public’s trust in its health agencies.”
Kennedy mentioned that patients are being treated with budesonide (a steroid), clarithromycin (an antibiotic), vitamin A, and cod liver oil. The federal government has also sent 2,000 doses of the MMR vaccine to Texas.
Vaccination Concerns
Gaines County, which has a large Mennonite population, has seen vaccine exemption rates rise substantially over the past decade. State health data shows that approximately 17.5% of kindergarteners in Gaines County had exemptions for at least one vaccine in the 2023-2024 school year, up from 7.5% in 2013.
Kennedy said during his Fox News interview: “In highly unvaccinated communities like the Mennonites, it’s something we recommend, but we also understand there is a lot of mistrust of the vaccines.”

He added, “There are people who should not be vaccinated in the community because they have autoimmune problems or other immune problems. If you do get vaccinated, you are protecting those people from a possible spread.”
Health officials emphasize that the MMR vaccine is highly effective, with two doses providing approximately 97% protection against measles.
