COVID Hits Black Americans Harder. New Vaccine Limits Increase the Risk Regulatory disorder at the CDC leaves it unclear who will be eligible for the shots and whether the vaccine will be free.

โ€œLimiting booster eligibility risks further compromising the already fragile health status of many Black Americans,โ€ Oni Blackstock, a physician and founder of Health Justice, a consulting firm that focuses on racial and health equity, previously told Capital B.

The Shutdown of U.S.A.I.D. Has Already Killed Hundreds of Thousands The short documentary โ€œRovinaโ€™s Choiceโ€ tells the story of what goes when aid goes.

One analytical model shows that, as of November 5th, the dismantling of U.S.A.I.D. has already caused the deaths of 600,000 people, two-thirds of them children. https://newyorkermag.visitlink.me/jUzNSc

Vaccine-Preventable Disease: A Global Tracker | Think Global Health This map is updated weekly and visualizes outbreaks of nine childhood diseases in collaboration with the International Society for Infectious Diseases

I'd love to say lots of nice things about this invaluable preventable disease tracker from @monscience.bsky.social and team at Think Global Health. It's an incredible resource.

But I can't get over my anger & sadness that this resource is even needed.

This has been a weird and awkward time! It's especially cool when my voice cracks in the middle of presenting something important. But in all seriousness, I'm deeply grateful for the support I've received so far. And if you're queer in academia too, feel free to reach out!

A tricky thing about transitioning in academia is forgetting who I've officially "told" and every email I'm like, "do I need to add my deadname to this?" So anyways I'm trans - if I look kinda familiar, you probably met me when I used a different name, which you can find in my orcid if desperate.

Matthew Shepard was murdered right when I was trying to come out of the closet. So like, this hit me pretty hard. Maybe thatโ€™s why I understand how important it is for trans kids to know they deserve to live.

The editors of the CDCโ€™s Morbidity and Mortality Weekly Report (MMWR) were apparently fired today.

The precursor to MMWR began in 1878 to address emerging public health threats rapidly.

We are not โ€œgreatโ€ without it. We are vulnerable to threats from sporadic foodborne illness to bioterrorism.

Monkeypox Monkeypox is a viral disease related to smallpox that spreads mainly through close contact.

#CDC is renaming #Mpox using the old misleading and stigmatizing term. #Mpox was set as global consensus by @who.int and there is no scientific or public health reason to go back to an outdated terminology.
What we need is action: vaccination, awareness & equitable access, not backward naming.

Shutdown Day Guide For LGBTQ+ People: "Continuing Resolutions" And New Anti-Trans Posts From The White House Shutdown day is here, and there has been a lot of competing coverage on Republican priorities, Democrat's demands, and what shutdown politics means for LGBTQ+ people in America.

1. It's shutdown day, and anti-trans provisions are on the line... either today, or in a few more weeks if a clean continuing resolution passes.

Trump posted a video this morning blaming a shutdown on trans people and immigrants.

Here is your shutdown guide.

Modeling the Health Impact of Discontinuing COVID-19 Vaccination During Pregnancy in the US This decision analytical model study estimates the number of avertable COVID-19 hospitalizations in US infants younger than 6 months and pregnant persons with vaccinations during pregnancy.

This medical startup uses LLMs to run appointments and make diagnoses

Very disturbing and unethical. Akido, a medical startup, is using an AI system to diagnose patients & provide treatment reca at clinical visits with medical assistants.

The worst part of all of this is who is being targeted (or tested) first w. this technology: Medicaid patients who are unhoused.

I was shocked to discover they're running PCR to detect seasonal coronaviruses at my local urgent care, reporting to IDPH and billing insurance (though I recall the out of pocket $ not being very high). I think these diagnostics are getting cheaper/more widespread than ever.

So I have a question...

RFK, Jr. says he does not believe "modeling studies" to estimate the number of premature deaths prevented by COVID vaccines, He want to see real data.

Question: What data does he have in mind?

Atlantaโ€™s HIV epidemic is real and itโ€™s driven by structural factors: lack of Medicaid expansion, racism, poverty, homelessness, limited comprehensive sex education, and barriers to HIV testing and PrEP access. Fear mongering to stigmatize certain communities is unhelpful and wrong.

No, Atlanta has NOT had 20,000 new HIV cases in 2025. Thatโ€™s a viral falsehood spreading on TikTok and Facebook .
As of 2022, ~43k people were living with HIV in metro ATL, and annual new diagnoses are in the hundreds locally (low thousands statewide) not tens of thousands in one city.

Thank you, Jeremy, for always speaking truth to power. The recent NIH "priorities" with regard to trans kids are based on a false, dehumanizing narrative that puberty blockers and gender affirming care is dangerous, when in fact, it is life saving. Our kids deserve better.

Gender Data Would Be Off-Limits Under Proposed NIH Policy A draft rule would bar scientists funded by the agency from collecting data about gender identity, following other steps the administration has taken to restrict research on LGBT topics.

Draft policy would stop NIHโ€‘funded researchers from collecting genderโ€‘identity data

This is a calculated and desperate attempt to erase trans and nonbinary people and to ignore their health needs, autonomy, and visibility, along with that of cis women.
