🎉 Happy (almost) New Year! Due to the holiday, our next podcast drops Friday the 2nd instead of Thursday. See you then!

New Osterholm Update podcast episode! @mtosterholm & @cvdall discuss why we shouldn’t compare other countries’ vaccine schedules to the US schedule. And Dr O continues to cover the infant botulism outbreak & answers an ID Query about New World Screwworm www.cidrap.umn.edu/a...

New! Public Health Alerts, a joint CIDRAP/NEJM Evidence effort to strengthen early detection and response to emerging health threats. First 2 reports: • Community transmission of clade Ib mpox in LA area • Flu virus characteristics and vax effectiveness data supporting WHO 2025–26 strain selections

Public Health Alerts reports are free, expert-reviewed, and designed to help public health leaders act fast. www.cidrap.umn.edu/public-healt...

In a world of profound change in public health, we are grateful to provide timely, comprehensive, and authoritative news, insights, and “straight talk” on emerging infectious disease threats. Please consider a gift to help make it possible, thanks!

This ACIP meeting set a historic precedent for the erosion and destruction of science-based vaccine programs in our country.

In voting to eliminate the universal birth dose of the hepatitis B vaccine, ACIP ignored decades of evidence confirming its strong safety profile and effectiveness. Its decision will result in more hepatitis B infections and more people with chronic liver disease.

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...

The infant botulism outbreak is an example of what public health does everyday to save lives--to identify the source and put an end to it.

Public trust is not a renewable resource. Our health agencies must be unwavering in their commitment to evidence, transparency, and integrity. Anything less jeopardizes the public’s ability to make informed decisions and ultimately puts more people at risk.

Don't miss this webinar happening TOMORROW #WAAW

Happy Day 1 of World AMR Awareness Week (#WAAW2025)! Today, we're highlighting some of the research that @cidrap.bsky.social has published over the years—from a 3-part analysis of outcomes research to a report on the introduction of typhoid conjugate vaccines www.cidrap.umn.edu/antimicrobia...

Just 10 days away! Make sure to register to secure your spot!

This is a wakeup call about society. It's not about politics, it's not about partisanship. It's about who we are as kind people.

A recent HHS video is filled with selective data and misleading claims about vaccines. Dr. Michael Osterholm of @CIDRAP breaks down how – and why - it misleads. 🎥 Watch here: youtu.be/Lh5hP6zcVrs

Latest from the Vaccine Integrity Project: Viewpoint: We owe parents real data before we mess with kids' vaccination schedule Combination vaccines exist for a reason: They reduce how many injections children receive and parents' stress www.cidrap.umn.edu/c...

New Osterholm Update podcast episode! @mtosterholm & @cvdall discuss recent layoffs & layoff reversals at CDC, comments from the administration on the MMR vaccine, the latest respiratory virus data, an update on pertussis cases, & herd immunity www.cidrap.umn.edu/a...

Science isn't truth, it's the pursuit of truth. As public health comes under increasing attack, we must stay rooted in evidence, whether we're talking about vaccines, acetaminophen, or COVID-19. Our communities' health depends on it.

"We are in a state of free fall." My new @vanityfair.com Q&A w/ pandemic preparedness expert @mtosterholm.bsky.social on publication of his new book, "The Big One: How We Must Prepare For Future Deadly Pandemics." www.vanityfair.com/news/story/p...

The latest "Viewpoint" from the Vaccine Integrity Project

The majority of Americans support vaccines, but misinformation is obscuring evidence of vaccine safety and efficacy. @mtosterholm.bsky.social talks about his work to uplift science-backed research and offers a readout on the most recent ACIP meeting. podcast.publichealth.jhu.edu/950-michael-....

A growing contingent of doctors say they are wary of federal health guidance under Robert F. Kennedy Jr.—and they are forming a parallel public-health universe.

CIDRAP is hiring a Deputy Director, who, in addition to other duties, will serve as a liaison between CIDRAP and other areas of UMN, so must either live in the Twin Cities area or have the ability to relocate upon accepting the position. Apply today! hr.myu.umn.edu/jobs/...

I have seen high school student council meetings run with more efficiency and effectiveness than last week's ACIP meeting. We recap the events in this special episode of the podcast.

As critical as I am of the CDC right now, I know many dedicated experts are still there. If we could hear their voices—not just political appointees—I’d feel differently. But the current messaging isn’t science-based, so I can’t trust the CDC or FDA at this time.

Broad access to vaccines of all sorts is in jeopardy, former CDC director Rochelle Walensky warns in an Op Ed in @statnews.com. www.statnews.com/2025/09/16/r...

“Allowing [access to vaccines] to be limited based on anecdote, whim, or flawed research is reckless and irresponsible.” That’s exactly what the CDC's ACIP risks doing. This isn’t just policy—it’s people’s lives.

Join us September 26 at 12:00PM ET for a conversation with @jennifernuzzo.bsky.social and @mtosterholm.bsky.social (@cidrap.bsky.social) where they will discuss how we can safeguard access to lifesaving vaccines and prepare for the next pandemic. Register here: brown.zoom.us/webinar/regi...

Come join the incredible team at CIDRAP News!

The Vaccine Integrity Project isn’t here to replace public health agencies or to tell anyone which vaccines to get. We're here to analyze and share the evidence.

Thanks for having me on, Eric!

Thanks to Mark, Ann, and Sydney for joining me to discuss the new book on the week's podcast!

Fear in public service doesn't always come as bullets—it can be threats, smears, or silence. I've felt it, and so have many of you. But courage means showing up anyway. You’re not alone. Take care of yourself. The work we do matters so keep going.

A sweeping review by the Vaccine Integrity Project suggests no new evidence that would prompt the recent changes to fall COVID vaccine recommendations made by HHS. @mtosterholm.bsky.social @cidrap.bsky.social www.medpagetoday.com/infectiousdi...

My comments with @cidrap.bsky.social today www.cidrap.umn.edu/covid-19/hhs...

The Trump administration cancelled about $500 million for research into mRNA vaccines. The move slows progress in using the technology to prevent a future pandemic or treat disease, experts say.

I don't think I've seen a more dangerous decision in public health in my 50 years in the business. Here's a special audio statement on my reaction to the HHS breaking announcement that it is terminating $500 million in investments in mRNA vaccine research. More details to come in today's podcast.

This is clearly a time where we could use science-based recommendations for vaccine use, and I don't think we're going to see it from this HHS.
