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

Ideal? Not even close. But now, there might be something useful in that DNA. 154
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.

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 · 05/12/2025All 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.

Jason L. Schwartz @jasonlschwartz.bsky.social · 04/12/2025Not remotely the most important ACIP observation, but I’m struck by how they’ve transformed the setup into something that looks like an official CDC broadcast rather than an actual advisory committee meeting.
