If you’ve read the book recently, you’d know that the topic of conversation at last night’s White House ‘Gatsby Party’ was probably very similar to what Fitzgerald wrote in 1925.

Yesterday, RFK Jr announced the U.S. wouldn't continue to support Gavi, the leading international vaccine organization.

I had a lot of thoughts, so I put them in my first ever Substack.

tl;dr—this is RFK Jr taking his anti-vaccine crusade global.

The measles vaccine is proven to work. It has saved millions of lives. That’s an undeniable fact, no matter what anyone says.

The ‘treatments’ repeatedly touted by RFK Jr—budesonide, clarithromycin, and cod liver oil—do not. No matter what anyone like him says. 🧵

An incredibly passionate and moving presentation by @madhupai.bsky.social on global health equity and allyship today at Brown University.

His energy, expertise, and insistence on hope at this dark moment are exactly what we needed right now! 🙏

“you can think of measles cases as a probe for whether we are paying attention…While measles is often first, it is a harbinger of problems to come.”

Highly recommend ‘Booster Shots’ by @adamratnermd.bsky.social. Crucial for understanding the history of measles and what the future likely holds.

It was deadly scandals involving things like 'swill milk', patent medicines including actual snake oil, and tainted food that led to the creation of today's FDA.

With less oversight of the things we eat and drink, it is only a matter of time before we deeply regret these cuts.

The measles outbreak in Texas continues to grow—36 more cases in the last week, up to 597 total

The true number of cases is certainly much much higher

And consistently 97% of cases are in the unvaccinated

We don't need more studies

The data has been—and remains—very clear
April 18, 2025 at 3:02 PM
So, why does all this matter?

We should certainly take it as a win that RFK Jr has finally endorsed vaccination to prevent measles.

But he MUST do more

Kids are dying of other vaccine-preventable diseases, largely due to his work over decades undermining vaccines
April 7, 2025 at 4:11 PM
In the same post, however, he deliberately added a falsehood

In fact, he edited a falsehood IN to his post AFTER posting it

His edited post included 'the growth rates for news cases and hospitalizations [from measles] has flattened"

Sounds nice

But that just isn't true
April 7, 2025 at 4:11 PM
Moving on from Malone's misinformation...

Today, RFK Jr broke his silence and fully endorsed measles vaccination as "The most effective way to prevent the spread of measles"

Well, in the third paragraph of an X post, at least
April 7, 2025 at 4:11 PM
I'll skip over the other falsehoods to touch on this common refrain:

Kids are dying — not because of measles — but because of medical malpractice

They said the same thing after the first child died of measles

They are saying it again

And they will say it next time too
April 7, 2025 at 4:11 PM
It gets worse

He goes on to say:

"Measles outbreaks are common, in both vaccinated and unvaccinated regions."

This is such a lazy lie

Do measles outbreaks occur in 'vaccinated regions'?

Yes

BUT ALMOST EXCLUSIVELY AMONGST THE UNVACCINATED

Look again at Texas now...
April 7, 2025 at 4:11 PM
This makes no sense. Like, none.

But he uses words like 'acute respiratory distress syndrome (ARDS)' and 'gram positive cocci', so who wouldn't believe him??

Those 'gram positive cocci' are bacteria from a severe infection
April 7, 2025 at 4:11 PM
His post is from 6pm yesterday, 12 hours before the NYT and others wrote about this

He is clearly getting insider and earlier information

He says a 'licensed Texas physician with significant experience treating measles', perhaps the same who has been pushing false treatments
April 7, 2025 at 4:11 PM
In his post last night, he tells the story of what supposedly happened leading up to this newest measles death

He also shares a LOT of very incorrect medical information, mistruths, and plain out lies

But there's something even more interesting to me about his post...
April 7, 2025 at 4:11 PM
Many saw a NYT story yesterday morning about the second measles death

At that time, it hadn't been confirmed by HHS, CDC, or the Texas Department of Health

Apparently, the cause of death was 'still being looked at'

Which reads to me as a way to buy time to control the narrative
April 7, 2025 at 4:11 PM
Texas, the epicenter of the current outbreak, has reported nearly 500 cases

And that outbreak has seeded cases in numerous other states, including across the country

According to the Texas Department of Health, 98% of all cases — and all deaths — were in the unvaccinated
April 7, 2025 at 4:11 PM
In 2000, measles was declared eliminated in the United States

There were sporadic importations and some localized flareups

But what we're seeing now is likely just the beginning of bigger, more frequent, and more geographically diverse outbreaks here

h/t @erictopol.bsky.social
April 7, 2025 at 4:11 PM
Let's start with what we know

The death announced today was in an 8 year old girl

The hospital reports she died of 'measles pulmonary failure'

They also report she was unvaccinated

And had no other health conditions

An absolute tragedy. And completely preventable.
April 7, 2025 at 4:11 PM
Yesterday we learned the sad news another child died from measles in Texas.

We also learned what RFK Jr. will and will not say

And we got a clearer glimpse of the playbook being used to discredit the proven measures to tackle measles outbreaks

Let me tell you why I'm worried 🧵
April 7, 2025 at 4:11 PM
The U.S. has actively dismantled the global disease-detection programs we all—including Americans—rely on to stay safe

Today this administration’s short-sighted global health agenda got even even worse

It’s ending its support for vaccine programs around the world

Why?? 🧵

Tonight we were so lucky to hear from my friend and colleague @jennifernuzzo.bsky.social on ‘Pandemic-Proofing the Future’.

She was chosen for the Brown University Presidential faculty Award and we couldn’t be any luckier to have her and her leadership at @pandemiccenter.bsky.social.

This is USAID’s page on X.

It’s been scrubbed clean.

And hours ago Rubio announced that the overwhelming majority of USAID projects are gone forever.

Including disease-detection and outbreak response abroad.

They cut Ebola prevention funding…the day after they promised they didn’t.
March 10, 2025 at 2:39 PM
Imagine this dysfunction ⬇️ …

but for all of global health. Where the stakes are MUCH higher.

Feeding USAID “into the wood chipper”, withdrawing from WHO, and muzzling the CDC are all short-sighted moves that’ll make us less safe.

We will regret this.
