ACIP has voted 8-3 to change the infant vaccination schedule for hepatitis B. Meissner, Hibbeln, Pollack voted no. Here's the language.

EtR and GRADE are not magic words just because you don't know what they mean or how to implement them, Restef. Stop cherry picking data. #ACIP

If #ACIP recommends against universal hep B vaccination, we will not observe a difference for another 50 years -- when people born after 2025 start developing liver disease in 2075 and beyond.

Huge disconnect noticed this morning with surveillance data and now. Yes, 60-year old adults are getting diagnosed with chronic hep B because their livers are starting to fail. What is missing is that most of them acquired the infection in early childhood, which we can prevent w universal vax! #ACIP

ACIP has just voted 6-3 to put off all of the hepatitis B birth dose vaccine dose votes until tomorrow, Friday. #CDC #IDsky #vaccines #hepB #pediatrics #familymedicine #obgyn

The CDC provided some real-world data on community/household transmission of Hep B at the last ACIP meeting. It happens.
- Prior to HepB BD, some U.S.-born children born to immigrant mothers without HBV infection had hepatitis
B prevalences of 7–11%2,3 attributable to community or household exposures.

The most vulnerable point in the life of a liver isn't when a person is 40, 50, 60, or older. It is when they enter this world. A few facts about HBV and the birth dose vaccine (in case you hear otherwise this week): #HBV #hepatitis #vaccines #ACIP #KeeptheBirthDose

Another thought about the #ACIP voting questions. Can they vote on screening? I was under the assumption that they can only vote on vaccine recommendations given the current healthcare setting and landscape they would be provided.

Why are we discussing votes already? Why are they only be read aloud and no slides? So they can't be screenshotted? What a mess. #ACIP

Risky behavior for acquisition of hep B in children include: putting things in their mouths, biting, scratching, touching their eyes, etc. "Waiting for vaccination until risky behavior" = shortly after birth, so no change? #ACIP #hepatitisB #HepBVaccine #vaccines

So far, the Temu ACIP meeting is basically a bounce house of misinformation.

Does anyone know of a good US measles tracker? I’m trying to avoid checking each state DOH (or even more local) and the CDC isn’t breaking down by state (just ranges) nor by the 3 defined outbreaks. Please help! #measles #IDsky #Medsky
