This is perfect timing as Victoria will present these data at the @polybioRF symposium today. (2/)

Based on cerebrospinal fluid cytokines, we identified two clusters of ME/CFS patients. Cluster 1 had elevated matrix metalloproteinases & many cytokines compared to cluster 2. Other than older age (Cluster 1), clinical presentation of these clusters was similar. (3/) Image

Published today📣
Our nasal booster in the "Prime & Spike" vaccine works without adjuvants (which are needed to induce adaptive immunity but also cause inflammation). @Kwon_Dongil @tianyangmao @BenIsraelow et al. asked how this is possible. (1/)
nature.com/articles/s4159…
Prime & Spike is a vaccine strategy that leverages preexisting immunity primed by conventional vaccines to elicit mucosal IgA and T cell responses that prevent COVID infection and transmission in rodents. The nasal booster is simply the spike protein (2/) science.org/doi/10.1126/sc…
Our new study shows that the nasal spike protein booster converts lymph node memory B cells into IgA-secreting cells in the lung with the help of memory CD4 T cells. Ag-specific CD4 T cells replace all the necessary functions of adjuvants without nonspecific inflammation! (3/)

This prospective observational study led by @connorbgrady @bornali_27 @SilvaJ_C @hmkyale examined the impact of the primary COVID-19 vaccination on the symptoms and immune signatures of 16 people with #longCOVID. Here is what we found 👇🏼 (1/)

nature.com/articles/s4385…
This study asked: Does COVID vaccination improve symptoms of long COVID? If so, is the improvement due to robust T and B cell responses leading to the clearance of the viral reservoir? If not, is there an immune feature that predicts worsening of LC? (2/)
The self-reported impact of vaccination was variable. Of the 16 long COVID patients, 10 felt better, 3 had no change, and 3 had worse health (1 hospitalized) 12 weeks after vaccination. Both physical and social effects of symptom burden appeared to decrease after vaccination. (3/)Image

"We will take your baby and deport you without her.”

Blockbuster new report from us @RefugeesIntl and our partner @humanrights1st documenting shocking stories of asylum seekers unlawfully disappeared, abused, and expelled by Trump's @CBP and @ICEgov.

Read on. 🧵 Image
Our teams interviewed numerous asylum seekers who have been unlawfully expelled from the US to Costa Rica, Panama, and their home countries (where they face real risk of persecution or torture, likely constituting refoulement).
We found a consistent pattern of government abuse and deception intended to subvert legal oversight and to deny people's rights.

Some of these accounts appear consistent with the practice of enforced disappearance under international law.

Teachable moment here.

I don't love using the term "humanitarian principles" b/c it sounds like an ethical creed.

That's not what the principles are. They are fundamentally a *tool* to enable safe humanitarian access.

A tool refined by years of hard lessons.

Quick🧵
Saying something "contravenes humanitarian principles" rarely persuades non-humanitarians.

When I was in government, that approach never worked.

Instead I would argue for why supporting independent, neutral humanitarian action *stood the best chance of operational success.*
I see the principles as two pairs:

The *what*: hum'n action seeks to protect life (Humanity) on the basis of need alone (Impartiality).

The *how*: hum'n action does not take sides in a conflict (Neutrality) and operates apart from political & military objectives (Independence) Image

More an amputation than a major re-organization.

The core structure of @StateDept remains intact and mostly unchanged.

But they amputate the US government's foreign aid capacity and eviscerate other soft-power tools.

A 🧵
Here's a cross-walk of the prior State org chart to the new one released by Rubio (links to both below).

🟥 items appear to be fully eliminated.

🟨 items are retained but reshuffled

🟩items are new to the org chart

New: state.gov/wp-content/upl…
Old: 2021-2025.state.gov/department-of-… Image
Image
DepSecs unchanged.

5 of the 6 undersecretaries unchanged; 1 eliminated and replaced by a revising the foreign assistance budget director (Marocco's old job).

Primacy of the regional bureaus is preserved/reinforced.

No cuts announced to overseas posts.

I saw firsthand the impact of stop-work-orders/terminations at USAID & now Harvard.

My new @NewYorker piece is on the serious implications for the lives of millions across the world and the US – including for my own family and very possibly your own. 🧵 newyorker.com/news/the-lede/…
These attacks are part of a broader assault on America’s health-and-science infrastructure. >90% of the $9B in federal dollars for Harvard that Trump has threatened supports life sciences – including heart disease research that saved my son’s life and guides his future care. Image
My family is far from unique. If you or someone you love has cancer, cardiovascular disease, dementia, Parkinson’s disease, or diabetes, you have likely benefited from the university’s federally funded discoveries. harvard.edu/research-fundi…

Most people haven’t heard of this test, which is available in the US. It accurately predicts Alzheimer’s (not just if there’s a risk, but when). It is favorably affected by exercise and likely many other lifestyle factors.
Here’s (almost) everything we know about it. In Ground Truths (link in my profile d/t X-suppression)Image

1/ The CMS final 2026 rate notice for Medicare Advantage just dropped, on the "no later than" date of April 7

The final rate is up- by a lot more than industry consensus of 75-100 bps!

I think a lot of plans are going to feel a little relief about their preliminary bids tonight Image
2/ One sell side analyst said "the most bullish expectation we heard [before] was a +125bps improvement"

ahem... my expectation was better than that, but even I didn't think it would be 310 bps better.

So why?

Because Dr Oz likes Medicare Advantage?

3/ If you missed, go back ands read my January tweetorial on the Advance Rate Notice (which was already "better than expected")

The short answer is that each year's "FFS growth rate" includes a true up of CMS actuaries' past and future cost estimates

We’re still learning about the steep cuts to CDC, but I want to focus on the particularly dangerous and misguided elimination of CDC’s tobacco control program. If it’s not reversed, this would have devastating consequences and put American lives at risk.
Although FDA regulates tobacco products, setting rules on manufacturing, requiring warning labels, and overseeing how tobacco products are advertised and marketed, FDA alone can’t prevent tobacco addiction.
CDC plays a distinct and essential role—tracking tobacco use, analyzing the burden of tobacco-related disease, and sharing vital data with communities, researchers, and policymakers.

Aid leaders have been warning for 2 months that the gutting of @USAID would leave US unable to respond to major global disasters.

We are now seeing that play out in real time with the Myanmar quake - reality is calling bullshit on the Trump admin's narrative.

🧵
In today's press briefing @statedeptspox bizarrely "rejected the premise" that a meaningful US response requires USAID staff "to be physically there."

As the guy who used to deploy those teams - this is total nonsense.

You can't conduct search-and-rescue virtually. Come on.
The reality is that other countries began deploying their teams immediately - and the US would have too, under any prior administration (including Trump 1).

But Elon, Pete Marocco, and Rubio have wrecked the USG's ability to do this.

OK, @elonmusk, challenge accepted.

Here's my own wall of receipts.

🧵
I posted this over a month ago on some specific line items on DOGE's wall of receipts, explaining how these violated the Rubio guidance on protecting lifesaving activities.
Among the first cancellations were fundamental humanitarian relief supplies.

1/ I love reading the annual March MedPAC report to Congress on Medicare Payment Policy

such good, clear data and policy thinking.

kudos to @medicarepayment staff and chair @Michael_Chernew

I'll post some thoughts/highlights as I read through this morning
2/ My focus will be on the areas I know best
-Primary care
-Alternative payment models
-Medicare Advantage
-Competition and consolidation

The report is here for those following at home.

medpac.gov/document/march…
3/ Here's the first nugget from their core responsibility - recommending payment rates to congress that ensure beneficiary access to care

Clinicians are paid 140% of Medicare by commercial plans... but you wouldn't know that by working with independent practices (as I do) Image

Seattle’s only national park honors the grit of the Klondike gold rush, where Donald Trump's grandfather built the family's early wealth.

But the DOGE cuts have placed the park’s future at risk.

A 🧵 about the park and Frederick Trump... Image
Image
There are some fascinating twists of history in this story.

Frederick Trump had his first foray into the world of hospitality as a 22-year-old in Seattle, when he opened a restaurant very close to the site of the current national park.

nytimes.com/2025/03/14/us/…
In 1896, Frederick Trump made the family's first foray into U.S. politics in the mining town of Monte Cristo. In a local campaign, he apparently allied himself with William Jennings Bryan, the populist Democrat who railed against tariffs.

In study led by Cassie Simonich & T McMahon, we quantify antigenic evolution of RSV F. Important because:

1⃣ RSV top cause of infant hospitalization in USA

2⃣ New antibodies & vax can prevent hospitalizations

3⃣ But will virus evolution erode efficacy?

biorxiv.org/content/10.110…
RSV has high burden in infants: top cause of infant hospitalization in USA, 2nd-leading cause of infant mortality globally

A monoclonal antibody (nirsevimab) recently recommended for infants born in USA in RSV season. It prevents hospitalizations

pubmed.ncbi.nlm.nih.gov/38457312/
RSV vaccines also now approved to protect infants (via maternal vaccination) & elderly

But some viruses evolve to erode antibodies and vaccines

Will RSV do same? Worryingly, a Regeneron antibody failed phase 3 trials due to resistance in some RSV strains

On claim after claim about @USAID / foreign aid, Elon is just making shit up as he goes along. No truth to any of it.

This claim is demonstrably false. Deaths have already been documented from the aid freeze. And the so called "sanity check" is a clown show of incompetence.
This is not a "brief pause." Aid orgs doing critical lifesaving work are being denied reimbursement for work already completed, and can't access USG payments to continue operations.

Many had their programs waived from the freeze, then terminated, then un-terminated.

A farce.
This is all hugely disruptive and the practical effect is global drawdown of lifesaving humanitarian and health activities.

Our @RefugeesIntl teams in the field over the past two weeks have documented widespread breakdowns of lifesaving relief operations in Syria & Bangladesh.

Yesterday, Rubio terminated 5800 USAID contracts – more than 90% of its foreign aid programs – in defiance of the courts.

Here’s a list of just some of the lifesaving awards that were terminated. Nearly all were Congressional mandated. They've saved millions of lives. 🧵
1. All malaria supplies protecting 53 million people, mostly children, including bed nets, diagnostics, preventive drugs, and treatments – terminated.
2. All tuberculosis programs, including the Global TB Drug Facility – terminated.

So - I've actually led Ebola outbreak response at @USAID.

This is bunk from Elon. They have laid off most of the experts, they're bankrupting most of the partner orgs, have withdrawn from WHO, and muzzled CDC.

What's left is a fig-leaf effort to cover their asses politically.
I led USAID's response to the 2014-15 outbreak in West Africa.

Also went to Congo with WHO to assess response at peak of the 2019 outbreak (under Trump 1).

Those were both robust USG ops.

That capacity has now been wrecked.
cgdev.org/publication/st…Image
Normally there would be:
- resources rapidly pushed to partners & host govt
- robust interagency (USAID/CDC/DOD) teams deployed to field, backstopped by Ops Centers in DC and Atlanta
- real-time operational cooperation and info-sharing with WHO

But not this time.

Train wreck coming.

A federal judge has ordered the USG to lift the aid freeze, pay what it owes, and show evidence that it has not been defying the court.

Which the USG can't do, because Pete Marocco has been defying the court and has purged the staff who move those payments.
It is clear as day that Marocco has made no effort to comply with multiple orders from the court to lift the arbitrary & capricious aid freeze.

He is likewise defying @SecRubio's order to waive lifesaving assistance.

Virtually no money has been unlocked by either order.
And Marocco's ongoing purge of @USAID personnel means it's functionally impossible to comply with these orders.

He and DOGE have pushed out nearly the entire workforce that would normally process these payments, knowing full well this makes compliance with the orders impossible.

Our preprint on post-vaccination syndrome is out. We studied immune signatures and examined spike protein in the blood of people who have developed chronic illnesses after COVID-19 vaccination. (1/) medrxiv.org/content/10.110…
Vaccines have saved countless lives and inspired me to become an immunologist. While generally safe, some people experience adverse effects, including Post-Vaccination Syndrome (PVS).

Measles cases may likely grow into the 1000’s

The TX measles outbreak continues

With “bubbles” of undervaccination getting bigger, we can expect outbreaks in one to catch on to the next

Igniting transmission that may catch and spread across the U.S.

cnn.com/2025/02/18/hea…
One of the most common tropes is that measles is fine & doesn’t cause damage…

This is highly inaccurate

Measles literally grows by infecting and killing memory immune cells. It causes loss to existing immunity creating vulnerabilities & acute damage that is often severe

2/
To discover the massive-stealth-impact measles has on immune protection against infections not associated w measles, we looked at what happened in populations after measles outbreaks swept through, decade after decade across nations…

What we found was astonishing…

1/ After residency at Mass General Hospital, I reported to Atlanta to meet my fellow CDC Epidemic Intelligence Service Officers.

I have never felt so intimidated by my peers

The best and the brightest, they were star clinicians, had served in disaster zones; MD/PhDs and MSF.
2/ We were placed at various centers throughout CDC, learning from the world's experts- in tuberculosis, mosquito-borne diseases, food-borne diseases, ...

and some of us were placed with state & local Health departments to be on the front lines of outbreak response
3/ In my first day on the job, I got into a city sanitation car to investigate an outbreak of bloody diarrhea at a state psychiatric facility.

My boss has served in the EIS. Her boss, the legendary head of the NYC Bureau of Communicable Disease had also.

Our commissioner too.

So...Max Primorac was the lead anti-USAID witness in the House hearing this morning and is one of the architects of the assault on the agency.

He made a few odd claims about his credentials at USAID in today's hearing.
He claimed that he "oversaw containment of two Ebola outbreaks and led the Bureau for Humanitarian Assistance."

Neither of these claims are accurate.
On Ebola - there were two outbreaks in Congo in 2018-19 - a small one in Equateur and a huge one in Eastern DRC.

Tim Ziemer, a well-respected health leader, was overseeing Ebola response for USAID.

Max was working on religious freedom programs.
