Check out this @nature.com News explainer article on measles, with my comments about our prior work, and featuring an upcoming article led by Drs @malar0ne.bsky.social and @joshuasweitz.bsky.social: www.nature.com/articles/d41...

We are thrilled to welcome three new Associate Division Chiefs to the Infectious Diseases Division! Dr. Brian Blackburn will be leading Education and Trainees, Dr. Prasanna Jagannathan will be heading Research, and Dr. Mindy Sampson will be taking on Hospital and Clinics.

NEW: South Carolina’s measles outbreak is country’s largest in more than 25 years. But its falling vaccination coverage + rising religious exemptions from school requirements don’t make it an outlier. My story. Gift link. 1/3 wapo.st/4rttZRg

(1/2) MMWR: Measles Outbreak Linked to Air Travel — Colorado, 2025 An unvaccinated traveler exposed others during an international flight and at Denver International Airport, leading to: • 9 secondary & 1 tertiary case in Colorado • 7 more cases in other states • 4 hospitalizations, mostly unvaxxed

In a new preprint, we combine modeling with school-level vaccine data to contextualize the risk of 'breakthrough infections' and impacts on the ongoing US measles outbreak. #idsky #episky www.medrxiv.org/content/10.6...

The killing of Alex Pretti is a heartbreaking tragedy. It should also be a wake-up call to every American, regardless of party, that many of our core values as a nation are increasingly under assault.

Alex Pretti, who is identified as the man fatally shot by a U.S. Border Patrol officer in Minneapolis on Saturday, was an intensive care nurse dedicated to treating veterans. Read more about him here: https://wapo.st/3M62eyV

Our latest study in @jama.com on trends in county-level vaccine exemptions, demonstrating geographic pockets of high vaccine exemptions and high susceptibility to vaccine-preventable diseases. Great collab with @nbcnews.com colleagues and our Stanford team. jamanetwork.com/journals/jam...

County-level data indicate a sharp rise in nonmedical childhood #vaccination exemptions in the US from 2010 to 2024, with post-pandemic rates highest in Utah, Idaho, Oregon, Wisconsin, and Arizona. ja.ma/4qky0qM

In a new, timely project led by @nathanlo.bsky.social, we collected vaccine exemption rates (mostly) at the county-level for nearly all states. Now up at @jama.com: jamanetwork.com/journals/jam...

This is so incredibly heart-breaking. To Jay Bhattacharya and Matthew Memoli at NIH--you have betrayed the entire scientific community. Deeply committed staff are leaving in droves--because you are destroying the institution. Shame on you. www.statnews.com/2026/01/10/n...

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.

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...

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.
