Biss’ “On Immunity” — my spring break ‘gift’ for my undergrads in my social history of vaccination course. A decade old now, but still holds up as a really thoughtful reflection on vaccine hesitancy as experienced by parents just trying to navigate this topic amid so much noise and anxiety.

I expect next week’s ACIP meeting to be canceled/rescheduled soon. FACA requires a notice in the Federal Register at least 15 days out (barring an emergency), which didn’t happen. And the public comment/docket process—typically set up weeks ahead—still points to last December’s meeting.

Lack of federal support means vaccine makers are investing less in R&D

Trying to imagine my reaction if someone had told me 18 months ago that this would be a slide I’d be showing in class today.

Appears I was a bit more fired up than usual in my analysis here.

All childhood vaccine recommendations are being reconsidered by ACIP, according to chair Kirk Milhoan, who slammed vaccination requirements for attending school and said vaccines should be taken on the advice of an individual’s doctor. www.theguardian.com/us-news/2026...

Issue is not w/ “shared decision-making” in its common usage in medicine—a very good thing!—but rather its specialized meaning in the context of types of vaccine guidance. A shrug rather than an endorsement. That would be clearer if it still went by one of its older names: “permissive use statement”

I think you should always listen to Peter Sandman, even if you don't agree. "Shared decision-making on vaccines is not the enemy," one of the great experts on medical decision-making writes in STAT. www.statnews.com/2026/01/26/s...

I know there's a lot going on in the world to track. Learning about the intricacies of our vaccine supply line shouldn't be one of them - yet here we are. New @newrepublic.com piece: newrepublic.com/article/2053...

RFK Jr.’s changes to the childhood vaccination schedule threaten the complicated and expensive process through which doctors stock vaccine doses.

newrepublic.com

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/...

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

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

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

A lot of the history and shape of American public health is explained by civil society (professions, health care institutions, philanthropy, even payers) designing policy to circumvent governments they never trusted. Ideal? Not even close. But now, there might be something useful in that DNA.

Jason L. Schwartz@jasonlschwartz.bsky.social · 8mo ago

As if it wasn’t clear long ago, it’s time to accept that the days of relying on the federal gov’t to lead vaccination work is over (for now, at least) and to focus on alternatives as if the longstanding HHS/CDC activities don’t exist. Because they don’t anymore! Time to be proactive, not reactive.
