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 🧵
Human vaccine responses regulated by parallel cytokine pathways
Nature Immunology - Chen and colleagues identify that baseline IFNβ levels correlate with antibody responses to inactivated influenza vaccines in humans, and show that type I IFNs, IL-12 and...

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...

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
Shared decision-making, informed consent, and the rhetoric of false empowerment
What these medical terms mean and how they’re fueling confusion about vaccines

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...

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.”
Tanya Lewis@tanyalewis.bsky.social · 8mo ago"The science is clear: the benefits continue to outweigh the risks by a wide margin,” @kkjetelina.bsky.social says of the black box warning FDA is reportedly considering adding to the COVID vaccines.

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.
Dan Diamond@ddiamond.bsky.social · 9mo agoCDC has overhauled its website to assert that “the claim ‘vaccines do not cause autism’ is not an evidence-based claim”
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.

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 CDC is falling deeper into crisis. What it means for the nation’s health.
Months of upheaval at the Centers for Disease Control and Prevention have undercut the agency’s work, employees said, and put the future of vaccines into doubt.

This is an extremely widespread view in public health. Daskalakis is one of the most respected health officials we have.
Ed@notdred.bsky.social · 11mo agoDemetre Daskalakis is an absolute GOAT of modern US public health, he should be the next head of the CDC and subsequently a US senator
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
