Some of the studies I find the most interesting are those that look into how to make vaccines work better, and recently, we got a really good one: rdcu.be/for77 Let's go through it 🧵

Sad events here at #ADA26 - ADA has chosen the side of this administration - pretending it's unsafe to an invited federal speaker to hand out an editorial - over supporting its own leadership who've dedicated countless volunteer hours to the org's right to protest. www.nytimes.com/2026/06/05/w...

This line from @kkjetelina.bsky.social 's latest substack regarding the ebola outbreak just hit me like a brick.

A year ago I warned what would happen if the US tore down our disease detection system around the world With Hantavirus & Ebola we are seeing VERY clearly what we’ve lost And why it matters Read my @theatlantic.com piece from last year outlining what happened www.theatlantic.com/ideas/archiv...

Worth your time to read. From @kkjetelina.bsky.social

Shared decision-making, informed consent, and the rhetoric of false empowerment: How HHS misrepresents SCDM, which is used by doctors in a very specific way - it does not mean "let's talk". open.substack.com/pub/yourloca... via @kmpanthagani.bsky.social

Wondering why there's such a fuss about pushing some #vaccine recommendations to "shared clinical decision making"? The term is being conflated with "informed consent," suggesting it's about empowering parents. This isn't that; good take here. yourlocalepidemiologist.substack.com/p/shared-dec...

Alex Pretti was a colleague at the VA. We hired him to recruit for our trial. He became an ICU nurse- I lover working with him. He was a good kind person who lived to help and these fuckers executed him. White. Hot. Rage.

That we're in a place, at a time, when someone has to write this headline, this article — it's almost unfathomable. Please do read @krutikakuppalli.bsky.social's take. www.statnews.com/2026/01/12/m...

The vaccine schedule change is "one of the most opaque & destabilizing public health decisions I’ve seen," says @kkjetelina.bsky.social "The result is painfully predictable: fewer children will be vaccinated, and children will be harmed" yourlocalepidemiologist.substack.com/p/a-unilater...

As always, women get the job done!

A thing that serves me well: ALWAYS take very seriously anything @kkjetelina.bsky.social says; she's 1 of the most trusted epidemiologists If FDA thinks risks>benefits, she says, "transparency about their data & reasoning is essential. Closed-door analyses won’t cut it. Americans deserves better.”

"As of December 14, the U.S. has had 391 mass shootings—more than the number of days in the year—for the seventh consecutive year. Seventy-five of these occurred at schools"— @kkjetelina.bsky.social

Dr. Katelyn Jetelina, an epidemiologist and one of the nation’s leading scientific communicators, will advise the CA Dept of Public Health on the critical need to maintain public confidence in the institutions that keep Californians safe.

Thank you for writing this, @meganranney.bsky.social.

Here we goooo. YLE is live tweeting. Follow Ed below.

I will be doing live coverage of the ACIP meetings tomorrow and Friday on Bluesky. Here's the agenda: www.cdc.gov/acip/downloa... And here is Your Local Epidemiologist and The Evidence Collective's prebunk: open.substack.com/pub/yourloca... Should be an interesting time

For the first time in my career, I can’t tell people to trust what the CDC website says. And that is an incredibly sad and devastating place for this country to be.

Teamed up with @kkjetelina.bsky.social for a post on the state of US health care—and why the ACA subsidy debate in Washington is too small. 1/x

Can’t believe I have to say this, but in Minnesota you will continue to have the freedom to get your COVID and flu shots.

School shootings, brace for vaccine headlines this week, Covid-19 vaccine access, another measles death, and more. by @kkjetelina.bsky.social yourlocalepidemiologist.substack.com/p/school-sho...

We need a public health expert in the United States Senate to hold RFK Jr. accountable.

NEW: The CDC has been in crisis for months. After the firing of its director, resignations of senior leaders, staff + experts are bracing for what could be death knell for public health credibility. Me + @laurenweberhp.bsky.social + @davidovalle.bsky.social www.washingtonpost.com/health/2025/...

The amazing Dr. Deb Houry— former and recently pushed out Deputy and Chief Medical Officer of CDC— is ready to join the public conversation. Follow her at @drdebhoury.bsky.social !!

This is an extremely widespread view in public health. Daskalakis is one of the most respected health officials we have.

only so many words you can put in a headline but the whole response is loud and proud support for the trans community and worth reading

CDC employees standing up and walking out in light of the mass shootings, firings, and *waves hands in the air* everything else. #USAnotRFK Lets gooooo

"CDC basically imploded yesterday and now it’s truly in shambles,” said @kkjetelina.bsky.social. Also: vaccines? My latest: www.theguardian.com/us-news/2025...

“Kennedy would be less hazardous if he decided to do cardiac surgery. Then he would kill people only one at a time,” writes former CDC Director William Foege. www.statnews.com/2025/08/18/r...

@kkjetelina.bsky.social Where "omg this is such a mess" meets "let's just press record and talk this out." tl;dr: Fall vaccines are anything but business as usual this year and all eyes will be on independent orgs and health insurance companies. Let's listen. open.spotify.com/episode/4C7p...

"We are drowning in the abnormal, yet forced to carry on our 'normal' lives, living in a constant state of cognitive dissonance." @kkjetelina.bsky.social yourlocalepidemiologist.substack.com/p/public-hea...

“Those bullet holes are a haunting, terrible metaphor for what public health has endured over the past six months—and the past six years.” @kkjetelina.bsky.social open.substack.com/pub/yourloca...

Four CDC buildings shot up. Employees under lockdown and in fear for hours. Public health is physically under attack, and the silence from the administration is deafening.

Public health has a communication problem, and we need to fix it. Excited to share our new piece in @nejm.org explaining the need to train more health communicators, with coauthors @meganranney.bsky.social, @kkjetelina.bsky.social, and @tedmelnick.bsky.social: www.nejm.org/doi/full/10....

It's exceedingly hard to argue that the administration & MAHA are committed to improving nutrition when they're simultaneously cutting everything from SNAP-Ed to innovative community nutrition work - cements the perception that food dyes are public health theatre. www.healthbeat.org/newyork/2025...

“...my biggest goal is to not turn people off that are curious… that means leading with a lot of empathy.” — @kkjetelina.bsky.social A powerful conversation on science, trust, and public health on Health & Veritas 🔗 insights.som.yale.edu/podcasts/hea... #PublicHealth #ScienceCommunication

This week, @texasmonthly.bsky.social’s reporting on the floods in Kerr County has been so purposeful and so deeply empathetic. It was personal. This first person account is so, so horrific and so beautifully written. You’ll cry very hard. (CW: Child death.) www.texasmonthly.com/news-politic...

"Instead of moving towards a health system that lifts people up—towards more prevention and better access to services, free from debt—we are moving towards one that increases bills, debt, and makes people sicker." by @kkjetelina.bsky.social yourlocalepidemiologist.substack.com/p/medicaid-c...

Annnnddddd ❌Thousands of Louisianans will lose healthcare. ❌33 LA hospitals are at risk of closing ❌Thousands of children won’t get food Seems like a real winner.

Sadly, I agree with most of this and it is nicely described and illustrated. Its clever to position the "hits" after the mid-term elections. This causes a challenge of how to describe the issue when its not being felt yet. yourlocalepidemiologist.substack.com/p/medicaid-c...

Just a reminder that saying something is “Gold standard” is much easier than working to make it as good as it can possibly be

USAID is shutting its doors today--marking the end of democracy, diplomacy, and decency all in one fell swoop.

Excellent interview by @danpfeiffer.bsky.social with @kkjetelina.bsky.social about the current status of vaccines in the U.S. Plus more on what the science really tells us about some of these bizarre MAHA claims. crooked.com/podcast/are-...
