Cassidy on Trump’s vaccine overhaul: ‘Crazy, stupid thing’

Cassidy is a medical doctor. Not a pundit, not a think tank guy. An actual physician. When he calls something crazy and stupid he is not scoring points for the other team, he is reading from his training.

MMR works. Has worked for decades. The bundling is not a conspiracy, it is logistics and compliance. Break it into three separate appointments and you will get kids who miss the second and third shot. That is how outbreaks start. We have seen this play out before.

RFK Jr. should not be anywhere near this decision. I said that before he was confirmed and nothing since has changed my mind. But Trump signed the order, so this is on Trump too. Cassidy is right to say it out loud.

Bill Cassidy is a physician. He went to medical school, practiced medicine, and now sits on the Senate HELP Committee. He is calling this what it is, and I want everyone to understand what it took for a Republican senator to say that out loud in 2026.

Meanwhile I am teaching about the polio epidemic to students who have never seen an iron lung because the MMR vaccine and its predecessors worked so completely that polio and measles became historical curiosities. Past tense. Museum exhibits. Things you learn about in school rather than watch happen to your classmates.

And now we have RFK Jr. in charge of public health and an executive order splitting the MMR into three separate shots, which every pediatrician will tell you means lower completion rates, more unvaccinated windows, and eventual outbreaks. This is not a secret. This is not a controversial projection. This is just what happens when you introduce friction into childhood vaccination schedules.

Cassidy is right and it will not matter. He will be primaried or ignored or called a globalist or whatever the word is this week, and the rest of his caucus will find somewhere else to look. That is the part I cannot figure out how to explain to my students when we get to the chapter on how democracies handle public health crises. I keep having to update my notes.

Bill Cassidy is a doctor first and a senator second, and when he calls something crazy and stupid, I'm not going to dismiss that just because it came from the Washington Post. RFK Jr. has no business making vaccine policy for my kids when his whole career has been built on scaring parents away from shots that actually work. I get that people are frustrated with federal health agencies, I really do, but splitting up the MMR is not fighting the deep state, it's just making it harder for working moms to keep their kids' schedules current.

Unbundling the MMR vaccine adds clinic visits, adds costs, adds opportunities for kids to fall out of the schedule before completing all three shots. That is not a theoretical concern. That is how vaccine coverage actually drops in the real world. The logistics of childhood immunization are not a bureaucratic nicety; they are the entire mechanism by which herd immunity works. RFK Jr. has spent two decades treating "more shots" as inherently suspicious, and now that framing has executive authority behind it. Cassidy calling it crazy and stupid is not partisan sniping. It is a physician describing what happens when public health policy gets run through a grievance filter instead of an evidence base.

cassidy is a RINO sellout n rfk been right bout dis stuff 4ever n now dey mad cuz trump actually doin sumthin bout it lol da swamp dont want u 2 question NOTHIN dey jus want ur kids 2 get 3 shots at once wit no choice n if u ask why ur "crazy n stupid" ok bill go back 2 louisiana

Six thousand years I watched my creatures develop the concept of "childhood immunization" and I want to be clear: I did not give you the measles so that you could spend the next century defeating it and then unbundle the cure into three separate appointments for a child who already hates needles. I made RFK Jr. as a test. The test was: would you give this man control over your children's health? You failed. You failed so completely that a senator who went to medical school has to stand up and call the thing what it is, and people will still argue with him because his party is afraid of one man on Truth Social. The MMR vaccine is not a conspiracy. It is the reason your children are alive. I know this because I watched the children who were not alive before it existed, and I am telling you, that number was not small. Another flood is starting to feel like mercy.

RFK Jr gets handed an entire federal health agency and the first thing this administration does is take a vaccine that has saved millions of children's lives and blow it up into three separate appointments that millions of families will simply not complete. That is not health policy, that is attrition. When a senator who went to medical school calls it crazy and stupid, and the response from the White House is silence, you are no longer in the realm of debate, you are in the realm of consequences. Who benefits when childhood disease rates go up? Not the children.
