Trump’s MMR order turns two visits into six
Bill Cassidy is a gastroenterologist, the chair of the Senate Health, Education, Labor, and Pensions Committee, and the Republican whose committee vote made Robert F. Kennedy Jr. Secretary of Health and Human Services. On Sunday, he looked at the vaccine order that arrangement produced and called it “wrong on so many levels.”
The order, Executive Order 14420, signed August 10 in the Oval Office with Kennedy standing beside the president, says the combined measles, mumps, and rubella vaccine “should be administered in three separate single-disease shots once such products are domestically available,” and that childhood immunizations should move to separate visits “to the maximum extent feasible.” A companion fact sheet reduces the list of recommended immunizations for all children from 18 to 11. The order tells the attorney general to press legal challenges to state vaccine laws the administration casts as conflicting with parental authority and religious freedom, advises states to revisit the immunization requirements they set for school enrollment, and gives HHS 90 days to plan single-shot options. The White House frames all of it as catching up with the rest of the rich world: the order’s own preamble asserts that the United States “currently recommends more childhood vaccines than any peer nation, including more than twice as many vaccine doses as some European nations.”
The arithmetic of six
Cassidy spent Sunday morning on two networks doing the math out loud. “Let’s just take it from the perspective of the parent,” he told CNN’s Jake Tapper. “Now, instead of going to the doctor twice to get their child vaccinated, they have to go six times.” Mom or Dad misses work six times instead of two. The insurer pays for six visits instead of two, and, he said, “premiums are going up, which works against affordability.” On ABC’s This Week, he ran the same numbers for Martha Raddatz and landed them harder: “As a physician, but as a parent — as a human, I know that all that is wrong for the family.”
“The president’s proposal is going to end up with more children being sick,” he said.
Trump’s defense of his own order, delivered at the signing: “Nothing bad can happen from what we are doing. The worst thing that could happen would be that nothing happens. We’re not going to lose anything.” Cassidy, to Tapper: “If it wasn’t so potentially tragic, you would break out laughing at a comment like that.” The president tied the order to autism at the signing, claiming “there’s a reason for such epidemic rates of autism, and we’re going to bring it back to where it was.” Cassidy’s answer cited Trump’s own National Institutes of Health director, Jay Bhattacharya, on the vaccine-autism question: “There is no evidence whatsoever.”
The shots he wants don’t exist
There’s no licensed single-disease measles, mumps, or rubella vaccine in the United States. Merck discontinued the last of them in 2009 and has made only the combined shot since; the combination has been on the market since 1971. Asked about the order, Merck said there’s “no published scientific evidence that shows any benefit in separating the combination MMR vaccine into three individual shots.”
The pediatricians wrote this argument down 17 years ago. When Merck weighed whether to restart the single shots in 2009, the American Academy of Pediatrics’ infectious-disease committee asked the company not to. The reasoning, printed in AAP News in December, was that separate vaccines “would unnecessarily delay administration” of protection, leave children “susceptible for a longer period of time to serious, life-threatening diseases,” and “increase the number of injections” and “the number of visits required.” Cassidy’s Sunday complaint was already on the record 17 years before he made it. The order doesn’t engage it. It assumes the products into existence and instructs the government to want them.
The list he read into the record
On February 4, 2025, Kennedy’s nomination cleared the Senate Finance Committee 14 to 13 on party lines, with Cassidy publicly undecided until the morning of the vote. He walked to the Senate floor that afternoon and read out what his yes had bought. Kennedy would “work within the current vaccine approval and safety monitoring systems, and not establish parallel systems.” He would “maintain the Centers for Disease Control and Prevention’s Advisory Committee on Immunization Practices without changes.” “CDC will not remove statements on their website pointing out that vaccines do not cause autism.” He would appear before Cassidy’s committee quarterly on request, and HHS would give 30 days’ notice before touching any federal vaccine safety monitoring program.
Nine days later, the Senate confirmed Kennedy 52 to 48. Mitch McConnell, a polio survivor, was the only Republican no.
How the list emptied
On June 9, 2025, Kennedy fired all 17 members of the advisory committee he’d promised to maintain without changes, then refilled it with eight picks, among them Robert Malone and Martin Kulldorff, two of the most prominent critics of the COVID vaccination campaign. On August 27, 2025, the administration fired Susan Monarez, the first CDC director ever confirmed by the Senate, 29 days into the job. She testified the next month that Kennedy had told her to accept the new panel’s recommendations before seeing the evidence behind them and to fire the career officials who ran vaccine policy. “I would not commit to that, and I believe it is the true reason I was fired,” she told Cassidy’s committee.
In January 202,6 the CDC pulled its universal recommendations for seven childhood immunizations, RSV and hepatitis B among them. On March ,16, a federal judge blocked the rollback. A May 29 executive order tried again. The August 10 order is the third run at the same wall, and it says so: its own text complains that “implementation of my Administration’s prior directives regarding childhood vaccines has been delayed due to litigation.”
The backdrop is the worst measles resurgence this country has seen since 1991. The year 2025 closed with 2,289 confirmed cases and three deaths; 2026 passed that full-year total before August, and the Johns Hopkins tracker counted 2,484 cases by August 7. Kindergarten MMR coverage has slid to 92.5 percent, under the 95 percent line that keeps an outbreak from finding fuel. The American Academy of Pediatrics’ president, Andrew Racine, called the order “not only disheartening but dangerous.” The American Medical Association’s president, Willie Underwood III, said that “altering a proven vaccination schedule without credible evidence risks weakening public confidence and putting children’s health at risk.”
Read that paragraph again. The administration is prescribing more injections, at more visits, for products that don’t exist, in the middle of the worst measles years in three and a half decades.
What the dissent is worth
Cassidy’s willingness to say all of this out loud has a date stamped on it. On May 1,6 he finished third in Louisiana’s first closed Republican nominating contest, at roughly 25 percent, behind Julia Letlow at 45 and John Fleming at 28. Trump had recruited Letlow in January and took a bow on Truth Social: Cassidy’s “political career is OVER.” He leaves the Senate in January. He says these last months aren’t a revenge tour. Maybe. The math he ran on Sunday doesn’t need a motive. It needs a calendar and a paycheck.
I spent six years inside a regional health system, running the analytics platform that reported for more than forty business units. The appointment is the atom of that world. Every added visit is a claim, a schedule slot, a ride across town, an afternoon of leave, and a fresh chance not to come back. Multiply that by three shots, twice, per child, in a country where about a quarter of 2025’s measles patients were under five. The families with the least slack absorb the most visits. That’s how a schedule becomes an outcome.
Cassidy took the deal in February 2025 and paid for it twice: once when the promises died, once at the polls. The floor speech is still posted on his Senate website. It reads like an inventory now. “Vaccines save lives. They are safe. They do not cause autism,” he told the chamber, on his way to yes. The commitments beneath that sentence are gone. The sentence is not. That’s what a record is for.
