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):

Responses to the Sounding Board piece by Prasad and Makary are now posted: www.nejm.org/doi/full/10.... Had I known that character limits would be so liberal I would have submitted a response, but these replies hit on all the key points.

Looking forward to the @pittpediatrics.bsky.social Grand Rounds tomorrow by @drannieandrews.com about her advocacy efforts. #pediatriciansforsenate

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. 🎉

1/ The first #ACIP meeting with RFK Jr.’s handpicked members wrapped up yesterday. Over 4,000 tuned in—a level of attention we haven’t seen since the pandemic. And for good reason: these meetings shape vaccine policy, coverage, timing, access and availability. Here's what happened 👇

Good timing for a stellar review on measles @nejm.org www.nejm.org/doi/full/10.... Only problem is that the people who need to read it won't

The Freeman lab is in search of a full time laboratory technician in Pittsburgh, PA. I particularly enjoy mentoring aspiring MD or PhD student scientists in this role.

Wow, this was an incredibly powerful statement put out by the now fired CDC ACIP members, published yesterday in JAMA. Snippets posted below: jamanetwork.com/journals/jam...

Helen Chu is one of the ousted #ACIP members. She spoke to me today about her grave concerns for future vaccination policy and vaccine access in the United States. www.statnews.com/2025/06/10/c...

If you have never stuck a needle in the back of an infant and watched pus drip out please don’t tell me I am overreacting to RFK Jr.’s latest assault on science.

Congratulations to Leigh Miller in the Alcorn Lab in @pittpediatrics.bsky.social for her upcoming thesis defense!

When Senator Bill Cassidy announced he would vote to confirm RFK Jr, he included this in his statement: “If confirmed, he will maintain the Centers for Disease Control and Prevention’s Advisory Committee on Immunization Practices without changes.” WITHOUT CHANGES.

How to spot terrible, no good, very bad information.

How bad will it be? Catastrophic. Proposed cuts to #NSF, #NIH, and #NASA will set the US R&D landscape back 25 yrs+, cause economic and job loss now, and undermine innovations to come. But, this is the WH's *proposed* budget. Speak up now before it is too late. (inflation adjusted $-s below)

Proud of Harvard for pushing back, exercising some creativity, and, maybe, helping folks get some needed education. Harvard is making many of their online government courses FREE. I just signed up for "Citizen Politics in America". They even asked me my Gender. pll.harvard.edu/subject/gove...

Some parents who never had #measles, never worried about #polio, who don't remember what life was like when kids caught these diseases, fear the vaccines that prevent them instead. @statnews.com's @thekibosch.bsky.social spoke to people who remember these foes. www.statnews.com/2025/05/10/w...

It’s just history repeating itself. The themes and doubts never change.

I attended a town hall last night for Sen McCormick (PA, R), who said he very much supports basic science funding and thinks the NIH budget should not but cut, but rather increase. He’d be very open to this argument so give him a call! 202-224-6324 Maybe other representatives feel the same!

Sort of looks like a new season is coming. 🤔

The number of confirmed #measles cases in the US this year — an unknown fraction of the true total — has hit 800, per #CDC, making this the 2nd worst year for measles since the virus was eliminated in 2000. And the year is young. The count in Texas is just under 600. www.cdc.gov/measles/data...

Wisconsin has seen a 1,450% increase in congenital syphilis cases since 2019, the state's Dept of Health Services reports. This at a time when the country's premier #STD lab has been shuttered in the devastating cuts at #CDC. What could possibly go wrong? www.statnews.com/2025/04/05/c...

Alaska has experienced an unusual outbreak of disseminated gonococcal infections. 90% of cases have required hospitalization. This marks a 10 fold increase in cases since 2022. The STI response branch of the CDC was dissolved 2wks ago. www-psychologytoday-com.cdn.ampproject.org/c/s/www.psyc...
