This is what a scientist looks like. 👩🏻‍🔬

Current measles situation… One month into 2026 (left column) we are at 26% of total cases. Cases continue to be overwhelmingly in un- or under- vaccinated children (who are reliant on adults to protect them with vaccination). #IDSky

There is a cost to science denial.

Given the current situation, it’s really important to know that a person can get the MMR vaccine for up to three days *after* exposure. This may help reduce the severity of the infection if not ward it off completely, but only for those in whom it’s not contraindicated. (1/2).

Oh cool! There's tons of evidence showing the newborn RSV shots cut hospitalization by ~80% in the first season. But this shows a major benefit persists in the second year, too.

The CDC changed the universal vaccine schedule & no longer recommends Rotavirus Hepatitis A & B Meningitis Influenza RSV I’ve cared for previously healthy kids who died from RSV, influenza and meningitis. We all are going to be caring for a lot more now. In our already overflowing hospitals

Viewpoint: The myth of an over-vaccinated America: The US DOES follow global consensus; Denmark stands out, choosing to protect its children less - which may work in a small, homogenous country with universal healthcare, but not in others. www.cidrap.umn.edu/vaccine-inte... @cidrap.bsky.social

I’m starting to think we should do a #medEd series on ‘recognizing vaccine preventable illnesses’. Anyone interested in coorganizing? #idsky #pedsid @pidsociety.bsky.social @febrilepodcast.com @idsainfo.bsky.social

There's a lot of focus right now on a person's right to choose whether to be vaccinated. But the risks falling vaccination rates pose to individuals — especially young babies, the elderly & the immunocompromised — need to be part of that discussion. www.statnews.com/2025/12/23/v...

Last weekend #USDA announced that Wisconsin had detected #H5N1 #birdflu in a dairy cow herd. Today the agency revealed that genetic analysis of virus from the herd shows this event was the result of a new spillover from "wildlife." www.aphis.usda.gov/news/agency-...

FDA approval 📢🔥 US FDA approved Nuzolvence (zoliflodacin) granules that dissolve in water. This medicine can treat uncomplicated urogenital gonorrhea in adults and children 12 years and older who weigh at least 77 pounds. 2 new oral Abx for gonorrhea #idsky gepotidacin www.fda.gov/news-events/...

"About 25% of children who develop chronic hepatitis B will die of their infection." --Dr. Andrew Pavia, pediatric infectious disease specialist, professor of pediatrics and medicine at the University of Utah, and spokesperson for the Infectious Diseases Society of America

A picture is worth a 1000 words. The birth dose of hepatitis B vaccines in the USA eliminated perinatally acquired hepatitis B infection from over 20,000 cases a year before the vaccine was introduced to <20 cases a year. The gaslighting by the current members ACIP is obscene, unethical and cruel.

The #ACIP meets tomorrow to assault on vaccines that protect children. They will be debating the birth dose of the hep B vaccine. I wrote about this previously but we cannot say it enough stopping the birth dose is unethical given the many benefits. bktitanji.substack.com/p/the-hepati...

CIDRAP’s Vaccine Integrity Project has released a major evidence review: 400+ studies/reports, 40 years of data—and the conclusion is unmistakable. There is no evidence supporting a delay in the hepatitis B birth dose. Full report: www.cidrap.umn.edu/vaccine-inte...

Excited to be a part of this inaugural class! 🎉 My very first paper was in #JVirology and I’ve been a fan ever since. 🦠

I couldn’t WAIT to get nirsevimab for my baby. He barely noticed when RSV circulated in his class. It was amazing. Starkly different from when my older child had RSV as an infant and nearly needed to go to the hospital.

“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

Honored to be selected for @socpedresearch.bsky.social and always looking forward to what my team will do next. 🦠

You can never be sorry enough for dropping the “h” at the end of Pittsburgh. That h really classes up the name, you know, makes it sound like the home of a Scottish Laird n’at. Cheers to Raleig for owning this treachery.

🧪A good perspective. Mothers from the 1950s, who saw how polio affected children's lives would like a word. For every $ spent on the MMR vaccine, the healthcare system saves $13. Now, The direct medical costs of a measles case is $1793. This translates to $~1.79B/yr for Americans.

We Are Not Going to ‘Solve’ Autism. And That’s OK. www.nytimes.com/2025/09/24/o... A beautiful piece by an anthropologist and father of a daughter with autism. “Good science takes years, not months.”

Check us out! Recruiting new colleagues!

Many studies have shown that there is no relationship between MMR vaccine and the development of autism. Here are two of the best. This one followed every single child born in Denmark from 1991 through 1998 (n=537,303). There was no association.

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...

The second to last child in this line to get his polio shot is none other than my friend @jimalwine.bsky.social. You know what’s even cooler? He went on to became a famous virologist who was one of the inventors of the Northern Blot. He wrote a blog post about this, which can be found below.

Really incredible effort by the indefatigable @nurseteria.bsky.social to raise awareness of what we are going to bring back by stripping access to vaccination 👇🏻

Acetaminophen/Tylenol use during pregnancy was not associated with children’s risk of autism, ADHD, or intellectual disability in sibling control analysis. This suggests associations observed in other, less rigorous analyses may have been attributable to familial confounding (aka erroneous finding):

July 1st is my favorite day in the hospital calendar. So many young talented physicians across the US officially start their physician careers today. Welcome to the new interns. It's a privilege to mentor you and see you blossom into caring doctors. We all were once interns 😊

here’s to doing more good science with good people. 🎉
