Things are very bad for U.S. vaccination policy these days and are only going to get worse. In @nejm.org, I examine the recent news about COVID-19 vaccines and ACIP, what likely lies ahead, and what the medical and public health communities should do to lessen the damage www.nejm.org/doi/full/10....

Revised Recommendations for Covid-19 Vaccines — U.S. Vaccination Policy under Threat | NEJM

A series of recent actions by the Trump administration upend the country’s approach to Covid-19 vaccination and may portend a broader shift in the government’s role in protecting the public health.

Respect the plaintiffs for standing up for process/principle, but _best-case_ outcome here would be HHS being required to temporarily repost old recs that they’d vehemently disavow, while continuing to undermine vaccination in 100 other ways. No silver bullet. www.washingtonpost.com/health/2026/...

Lawsuit contests RFK Jr.’s new vaccine guidance for children

Several public health organizations accused the health secretary of packing a key advisory committee with vaccine skeptics, arguing its latest guidance should be voided.

If you haven’t already, at some point may want to connect with @mattmotta.bsky.social and @thcallaghan.bsky.social, who lead a great research program at BU looking at state vaccine legislation

Happy to! Just DM me an email address where I can send it.

Important reporting from @HelenBranswell and @jaspar: The US is now a global outlier when it comes to vaccine schedules, recommending fewer vaccines than most of its peers. www.statnews.com/2026/01/09/c...

When it comes to vaccine schedules, the U.S. is now the outlier

A STAT analysis of vaccine recommendations in 38 countries suggests the U.S. is now an outlier.

I’ve been a fan of the Vaccine Integrity Project since its launch last year. Glad to be part of its new Board of Advisers announced today and contribute to its important work going forward.

“The concern is this is going to create widespread confusion about when those ‘special-category’ vaccines should be used, which will doubtlessly mean fewer kids will get those vaccines and more kids will get those diseases.” - @jasonlschwartz.bsky.social

Joined @kcbsradio.bsky.social in SF this morning for a long conversation discussing the new vaccine recommendations from HHS/CDC www.audacy.com/podcast/kcbs...

That change from 2 doses to 1 dose of HPV is noted deep in the 33-page ‘scientific assessment’ by Hoeg and Kuldorff that accompanies the HHS release. www.hhs.gov/sites/defaul...

Refers to this, but the only named in the document people are Hoeg and Kuldorff www.hhs.gov/sites/defaul...

Here’s the new schedule as released by HHS a little while ago.

Scoop: The Trump admin is planning to overhaul the childhood vaccine schedule, per person familiar.

The proposed new schedule would recommend fewer vaccines, bringing it close to or in line with Denmark’s schedule.

Stand down (for now). Hearing now that that announcement scheduled for tomorrow has abruptly been delayed until after the holidays.

Jason L. Schwartz @jasonlschwartz.bsky.social · Dec 18

Yeah I’m hearing bad (worse) things are coming.

Prof Gavin Yamey @gavinyamey.bsky.social · Dec 18

I would be willing to place a large bet that tomorrow’s “MAHA Wins” announcement with RFK Jr and Tracy Beth Hoeg will not in fact make children’s health better

My strong hunch is that it will be awful for child health

And I made my improv debut, playing a dad with varying degrees of concern about the MMR vaccine while the pediatrician modeled different approaches to addressing them—with equal parts evidence and empathy—to build trust and respond to ‘my’ fears

Jason L. Schwartz @jasonlschwartz.bsky.social · Dec 12

Contrary to the claim made at ACIP that med students are just told to memorize the CDC schedule, I just spent a great hour with the @yaleschoolofmed.bsky.social 1st year students alongside an ID doc and a pediatrician talking about measles, vaccine hesitancy, and how to talk w/ parents with concerns

The FDA says more information about claims that Covid vaccines resulted in death - for children and adults - will be coming "soon." But experts say the delay has been "striking." My latest:
