RFK Jr. went on national TV and spouted egregious, dangerous falsehoods about vaccines. As a parent and infectious diseases doctor, I couldn't stay silent. @FoxNews might not fact-check him, but I will. I've reviewed the trials. I've catalogued them. I have receipts. 🧵

2/ To be clear: the package insert is real — but it's being misread. That paragraph describes solicited reactions: sore arm, fever, irritability. Investigators actively asked about these specific symptoms for 4-5 days because that's how long acute inflammation lasts. It's a

No one lied. The insert accurately describes what it describes: the window for tracking solicited reactions — injection-site pain, fever, irritability. That’s the 5 days highlighted. What that section doesn’t spell out is the broader monitoring structure: unsolicited adverse

This is false. The “less than a week” figure is the diary-card window for tracking sore arms and fever — short because acute inflammation is short. Unsolicited adverse events were tracked for ~30 days after each dose, serious events were monitored for months, and post-marketing

Had a great conversation with Vincent Racaniello, Rich Condit, and Angela Mingarelli on This Week in Virology (TWiV) about vaccines and current policy. We kept coming back to nuance — something that's been in short supply lately. @profvrr https://t.co/3ph9avs2EW

So to be clear: ACIP didn’t vote to end the universal hepatitis B birth–dose recommendation because of new safety concerns. They did it to make a political point about mandates. Thank you for saying so explicitly.

@RetsefL Are you saying that a key criteria in how you vote and how ACIP crafts its recommendations is your worries about mandates that others might impose?

In Los Angeles County, due to the implementation of the universal birth dose and the partnership between Public Health, providers and parents, perinatal hepatitis B infection is extremely rare, with only one case recorded in the past five years.

Remember: RFK Jr. fired his last CDC director because she refused to ram through his anti-vax agenda. Yesterday, RFK Jr.’s handpicked vaccine skeptics threw out DECADES of settled science — and Donald Trump gave a thumbs-up. This will hurt American kids and families.

“The most dangerous misinformation is the kind that’s wrapped in the appearance of scientific authority.” - David Higgins, pediatrician, U of Colorado This week, ACIP provided exactly that. Excellent reporting by @bylenasun & colleagues that captures it all.

“You know… we feel a little bit like puppets on a string as opposed to really being an independent advisory panel.” – ACIP chair Dr. Kirk Milhoan Great piece by @bylenasun & @DavidOvalle305 https://t.co/Dc33wXVGlY

Apparently Denmark is our gold standard for healthcare now. I look forward to the White House plan to implement universal access to healthcare. https://t.co/9Au2TpCpiZ

The other irony: Siri’s favorite “smoking gun” – the unpublished Henry Ford birth cohort – actually reports no association between vaccines and autism. That part never makes it into his talking points. At the same time, a rigorous 2019 Danish study of 657,461 children (including

Aaron Siri spent hours at CDC’s vaccine panel pushing debunked claims. “If you’re going to say vaccines don’t cause autism, have the data to say it,” he said. We do have that data. What’s missing is evidence for his narrative. @ariabendix https://t.co/AFBQmof3pX

#ACIP voted to scrap the universal hepatitis B birth-dose recommendation. There is no new safety signal. No scientific rationale. We are dismantling a 30-year-old, cancer-preventing policy that has nearly eliminated hepatitis B in U.S. children. The babies who will become

Science would have kept a safe, cancer-preventing hep B birth dose in place. Ending it despite decades of reassuring — and newly updated — safety data, with no signal of harm, is politics, not public health.

And crucially, there is no new safety signal driving this decision. We’re rolling back a 30-year-old, cancer-preventing birth-dose policy with decades of reassuring safety data and no evidence of harm from the vaccine itself. That’s a reckless and dangerous way to make vaccine

To all the people saying that hep B only affects "people who do IV drugs and have orgies": https://t.co/h5lxMxcnG3
