ACIP votes to end universal HBV birth dose for newborns. The consequence? Prepare to see a reversal of our rates of chronic liver disease and liver cancer as more children are left unprotected.
The birth dose has an up to 90% efficacy rate of protecting newborns from Hep B, which is incurable.

So, to all the "RFK's got some good ideas" folks (Rachael Bedard, Leana Wen) and Jay Bhattacharya is "an excellent choice for NIH" (Steven Macedo, Frances Lee) and Vinay Prasad "will bring a breath of fresh air to FDA" (Adam Cifu, John Mandrola) groupies--you own this now too.
I think the *speed* at which RFK Jr and his Great Barrington Declaration/anti-vaxx/Brownstone wrecking crew have been dismantling the US public health system has been really astonishing
Well, Senators Bill Cassidy and Thom Tillis, you wanted RFK Jr. to “go wild” at HHS.
Congratulations. You’ve achieved your goal. He is well on his way to completely destroying the US vaccine program.

Brandolini's law example: "72 jabs" claim is old antivax BS--counts combined vaccines (like MMR) as if 1 shot for each. Ironically, HHS called for MMR into M, M, & R, thus 2 shots-->6.

Months 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.
