Many thanks @nytimes.com for highlighting our recent @jama.com paper led by @nathanlo.bsky.social @stanfordmedicine.bsky.social Trump’s War on Public Health Is a Battle to the Death www.nytimes.com/2025/12/23/o...

BREAKING: US. plans to stop recommending most childhood vaccines, defer to doctors, per sources familiar. HHS consulted w chief science officer and top FDA official. Me and @rachel_roubein 1/4 www.washingtonpost.com/health/2025/...

The pipeline of scientists is cracked at every level now: recent grads can't get jobs/research experience because we're all conservative about hiring in this climate, fewer grad school spots, killing many fellowship pipelines, and now the early career investigators are disproportionately impacted.

#COVID19 vaccination before or during pregnancy was associated with lower risks of hospitalization, ICU admission, and preterm birth among those infected with SARS-CoV-2 in Canada. ja.ma/3XUEa4p

A dystopian reality: unqualified decision makers with disregard for basic concepts in epidemiology, clinical medicine, and the evidence-to-decision guidelines process on full display at ACIP - leaving American children to bear the harm. (A few ACIP members excluded) www.nytimes.com/2025/12/05/h...

The health of Americans is at risk as those in power abandon evidence and process, and elevate anecdote and rhetoric in their place. Excellent article (if sad to read) www.statnews.com/2025/12/03/a...

- He stopped the policy of encouraging flu immunization in Louisiana - Delayed reporting on a pertussis outbreak that killed two children in Louisiana. -Promoted false information on covid vaccine harms. He is now number 2 at CDC. www.nbcnews.com/health/healt...

BREAKING: Louisiana health official who ordered his health department to stop promoting mass vaccinations during a surge in flu cases this winter has been tapped to be the new number 2 at @CDCgov. My story. www.washingtonpost.com/health/2025/...

Breaking News: Robert F. Kennedy Jr. said he personally instructed the CDC to abandon its position that vaccines do not cause autism. The move underscores his determination to challenge scientific orthodoxy — in this case, that vaccines save lives — and bend the health department to his will.

New study shows that shifts in SARS‑CoV‑2 Ct value distributions can help nowcast epidemic trends, revealing both strong potential and key real‑world limitations for Ct‑based surveillance. From CCDD alumni TY Lim & @jameshay.bsky.social and faculty @yhgrad.bsky.social at bit.ly/4o37EaN

“Since 1998, independent researchers have conducted more than 40 high-quality studies involving over 5.6 million people. The conclusion is clear and unambiguous: There’s no link between vaccines and autism." -Dr. Susan Kressly, AAP President on recent changes to the CDC's website

How awful. This is outright health disinformation, lying to the American people. Not only is there massive evidence showing no link between vaccines & autism, there’s not even a plausible mechanism based on what we’ve learned about the genetics of autism, some environmental exposures in pregnancy

Honored to receive the Ashford medal from @astmh.bsky.social. Much credit goes to my mentors, collaborators, colleagues, and our team @utah.edu @uofuhealth.bsky.social @uofumandi.bsky.social. Even more gratifying was seeing my trainees recognized for their work earlier in the day. #GlobalHealth.

As expected, Canada has lost its measles-free status because of the long-running outbreak there. With it goes the #measles elimination status of the entire zone of the Americas, the only division of the #WHO to ever have achieved measles elimination. www.statnews.com/2025/11/10/m...

We’re thrilled to welcome Dr. Paul Bollyky, MD, DPhil, as the new Division Chief of Infectious Diseases and Geographic Medicine at Stanford Medicine. Dr. Bollyky has been a dedicated member of our division, bringing deep expertise and a vision for advancing infectious disease research and care.

NEW @nejm.org: We synthesized 511 recent studies on Covid-19, RSV & flu vaccines for 2025-26. With federal advisory processes disrupted, clinicians & the public need rigorous, independent evidence synthesis. Here's what we found: 🧵 www.nejm.org/doi/full/10....

H-1B visa–sponsored physicians are twice as prevalent in rural counties and nearly 4 times as common in high-poverty areas, highlighting the potential harm of rising visa costs to health care access. ja.ma/47Iw84h

The thing about outbreaks of infectious diseases is that you can only hide them for so long. Time literally is containment. And the whistle always blows once people start to die ( in this instance babies). This is why we have public health surveillance and reporting. www.npr.org/sections/sho...

The National Academy of Medicine elected 90 new members, including 10 international, including our chair, @euanashley.bsky.social in recognition of his efforts to help lay the foundation for the use of the human genome in medicine. Congratulations, Euan! Read more: med.stanford.edu/news/all-new...

Mass administration of azithromycin to children younger than 5 years has been reported to decrease child mortality. In the LAKANA trial, limited to infants 1 to 11 months of age in Mali, azithromycin did not reduce infant or child mortality. Full trial results: nej.md/3W9ykeD #MedSky #PedSky

Just here to remind everyone that while the federal government is shutdown, all study sections at the NIH are currently on hold. Another blow to science and to early career scientists like myself with young labs and research groups. Very hard to remain positive about this career path.

In the era of widespread population immunity , among veterans COVID vaccines still reduced the risk for COVID related emergency room visits, hospitalization and death in the 2024-2025 vaccination season, especially in older veterans >65 years. www.nejm.org/doi/full/10....

More are united around a simple message: RFK Jr should not be HHS Sec. His decisions undermine our public health capacity and put lives and health at risk. As 6 former Surgeon Generals argue: "He has rejected science, misled the public and compromised the health of Americans." 🎁 wapo.st/3VTALll

💬 Viewpoint: The resurgence of #measles and erosion of immunization policy, coupled with declining vaccination rates and undermined public health agencies, threaten to return the US to an era of frequent, preventable disease outbreaks. ja.ma/4pU4BUO

New NBC story on measles outbreak in pockets of low vaccination - worrisome

25% of Drs in US are foreign grads. Many are on an H1B visa. This will hit health systems hard especially rural hospitals and hospitals in underserved areas that sponsor these visas through waiver programs. The old cost was about 5000$ a year. www.theguardian.com/us-news/2025...

I have to keep this deliberately vague, but this is a total disaster for academic research. And imposing it so suddenly is just cruel. I’ve got friends scrambling to get back to the US before midnight tonight. Do you know how hard that is to do on 36 hours of notice?

Immigrants, particularly on H1Bs, are the lifeblood of American innovation. If you wanted to hurt US competitiveness in the next century, I can think of few more effective ways than a move like this Even when found illegal, the mere intent will have irreparably harmed our future

My ACIP recap: 🧵 1) MMRV combo vaccine no longer recommended for children <4y. That means vaccine will not be covered by insurance, so not an option for patients. The 2 shot MMR and chickenpox vaccines are still available. This removes access. Let’s see which vaccine they will go for next!
