Friday is the first business day of the Morbidity and Mortality Weekly Report cycle that runs through Sara Brenner's office. The paper's Apr 30 account of Brenner's appointment to the new CDC leadership team named the principal-deputy line as the historic editorial gate for MMWR. Today is the first MMWR Friday inside that gate.

The queue is not theoretical. The Advisory Committee on Immunization Practices voted 8-3 on December 5 to drop the universal hepatitis B birth-dose recommendation and replace it with individual-based decision-making for infants of mothers who test negative for the virus. [1] CDC adopted the recommendation December 17. [2] The operational guidance — which dose, which day, which counseling script — still has to ship, and the vehicle is MMWR.

CIDRAP's published modeling found that ending the universal birth dose will drive higher hepatitis B infections, deaths, and costs. [3] The American Academy of Pediatrics, surveyed by Medscape after the vote, said it had found no new evidence supporting the change. [4] Both registers now wait on the same publication queue.

The vaccine-skeptic register celebrated Brenner's appointment as the institutional foothold the Schwartz pledge was meant to prevent. Eric Topol called the editorial-independence cost durable. Trade-press tracker Alexander Gaffney named Brenner as the senior FDA official under consideration for an HHS senior role weeks before the announcement [5]. The hep-B operational guidance is the first test of whether the queue moves, holds, or rewrites.

The unpublished Covid-vaccine MMWR the Washington Post reported on April 22 sits in the same queue. Two MMWR Fridays in May will tell readers which question routing answered.
