Jason L. Schwartz @jasonlschwartz.bsky.social · 16/02/2026I 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. 031

Jason L. Schwartz @jasonlschwartz.bsky.social · 26/01/2026Issue 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” 0111

Jason L.

Reposted by Jason L. SchwartzScott L Greer @scottlgreer.bsky.social · 06/12/2025A 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. 154
Jason L. Schwartz @jasonlschwartz.bsky.social · 06/12/2025Or the morning after the election, really. 130
Jason L. Schwartz @jasonlschwartz.bsky.social · 06/12/2025Months ago (pre-purge), colleagues I respect cautioned me about sounding the alarm about threats to ACIP (and vaccine policy generally), lest it undermine/delegitimize those things needlessly. So I waited until June (after RFK changed COVID recs, but before the purge). Probably too late even then. 1266
Jason L. Schwartz @jasonlschwartz.bsky.social · 06/12/2025As 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. 1193
Jason L. Schwartz @jasonlschwartz.bsky.social · 05/12/2025I’ve been watching ACIP meetings since 2006 and have spent a lot of time with their meeting materials going back to 1964. If there’s ever been another outside speaker who’s had 90 uninterrupted minutes to opine—let alone a non-scientist/physician/public-health expert—it’d be news to me. 062

Jason L. Schwartz @jasonlschwartz.bsky.social · 05/12/20254-5 ACIP members seem fundamentally opposed to the committee’s central purpose throughout its history—to provide population-level recommendations for how vaccines _should_ be used—viewing even a rec. as an impediment to informed consent, etc. So we’ll be doing this over and over for other vaccines. 2123
Jason L. Schwartz @jasonlschwartz.bsky.social · 05/12/2025Oh my, Tracy Beth Hoeg rejects the idea that the risk of an infectious disease for an individual differs depending on national/regional/local epidemiological contexts, health system considerations, etc. 040
Jason L. Schwartz @jasonlschwartz.bsky.social · 05/12/2025All this talk about the original approval and recommendations for the current HepB vaccines prompted me to dig out those 1986 ACIP meeting minutes, collecting dust in my files for years.
