So to be clear: ACIP didn’t vote to remove the hepatitis B birth dose because of new safety concerns. They did it to make a political point about mandates. Thank you for saying so explicitly.
Screenshot of a post on X from Retsef Levi (@RetsefL). The post reads: “ACIP’s recommendations re Hep B vaccine reflect strong objection to vaccine mandates that prevent access to school & even clinical care from children not up to date with the vaccine schedule (including Hep B). Children should have undeniable constitutional right to education! Should the constitution be amended accordingly?” The post tags @SecKennedy and @AaronSiriSG.

The ACIP decision to discontinue the recommendation for a universal hepatitis B birth dose vaccine will cause harm. As the federal government continues to fail children's health, families can rely on our nation's physicians to continue to put children's health first.

A claim that the U.S. is an “outlier” for having a universal hepatitis B birth dose is false. ACIP’s own September map shows many countries with universal birth-dose policies. We’d become an outlier only by rolling ours back. www.cdc.gov/acip/downloa...
World map labeled “Global hepatitis B birth dose vaccination policies,” with many countries in green indicating universal HepB birth-dose, others in yellow (partially universal), orange (selective), and red (no birth dose).

Man comes to the US from Lebanon. Starts out delivering pizzas, becomes a Nobel winning neuroscientist. Trump freezes his funding, he gets an email from China offering to move his lab “any city, any university I want" with guaranteed funding for 20 years. What are we doing?
Ardem Patapoutian's story is not just the American dream, it is the dream of American science.

He arrived in Los Angeles in 1986 at age 18 after fleeing war-torn Lebanon. He spent a year writing for an Armenian newspaper and delivering Domino's at night to become eligible for the University of California, where he earned his undergraduate degree and a postdoctoral fellowship in neuroscience.

He started a lab at Scripps Research in San Diego with a grant from the National Institutes of Health, discovered the way humans sense touch, and in 2021 won the Nobel Prize.

But with the Trump administration slashing spending on science, Dr. Patapoutian's federal grant to develop new approaches to treating pain has been frozen. In late February, he posted on Bluesky that such cuts would damage biomedical research and prompt an exodus of talent from the United States. Within hours, he had an email from China, offering to move his lab to "any city, any university I want," he said, with a guarantee of funding for the next 20 years.
