A federal vaccine advisory committee voted on Friday to end the longstanding recommendation that all U.S. babies get the hepatitis B vaccine on the day they’re born.

A loud chorus of medical and public health leaders decried the actions of the panel, whose current members were all appointed by U.S. Health Secretary Robert F. Kennedy Jr. — a leading anti-vaccine activist before this year becoming the nation’s top health official.

“This is the group that can’t shoot straight,” said Dr. William Schaffner, a Vanderbilt University vaccine expert who for decades has been involved with ACIP and its workgroups.

For decades, the government has advised that all babies be vaccinated against the liver infection right after birth. The shots are widely considered to be a public health success for preventing thousands of illnesses.

But Kennedy’s Advisory Committee on Immunization Practices decided to recommend the birth dose only for babies whose mothers test positive, and in cases where the mom wasn’t tested.

For other babies, it will be up to the parents and their doctors 

 if a birth dose is appropriate. The committee voted to suggest that when a family decides not to get a birth dose, then the vaccination series should begin when the child is 2 months old.

The acting director of the Centers for Disease Control and Prevention, Jim O’Neill, is expected to decide later whether to accept the committee’s recommendation.

The decision marks a return to a public health strategy that was abandoned more than three decades ago.

Asked why the newly-appointed committee moved quickly to reexamine the recommendation, committee member Vicky Pebsworth on Thursday cited “pressure from stakeholder groups wanting the policy to be revisited.” She did not say who was pressuring the committee, and a spokesman for Kennedy did not respond to a question about it.

Committee members said the risk of infection for most babies is very low and that earlier research that found the shots were safe for infants was inadequate.

They also worried that in many cases, doctors and nurses don’t have full conversations with parents about the pros and cons of the birth-dose vaccination.

The committee members voiced interest in hearing the input from public health and medical professionals, but chose to ignore the experts’ repeated pleas to leave the recommendations alone.

Dr. Peter Hotez of the Texas Children’s Hospital Center for Vaccine Development in Houston declined to present before the group “because ACIP appears to have shifted its mission away from science and evidence-based medicine,” he said in an email to The Associated Press.

 panel earlier this year and replaced it with a group that includes 

Hepatitis B is a serious liver infection that, for most people, lasts less than six months. But for some, especially infants and children, it can become a long-lasting problem that can lead to liver failure, liver cancer and scarring called cirrhosis.

In adults, the virus is spread through sex or through sharing needles during injection drug use. But it can also be passed from an infected mother to a baby.

In 1991, the committee recommended an initial dose of hepatitis B vaccine at birth. Experts say quick immunization is crucial to prevent infection from taking root. And, indeed, cases in children have plummeted.

Still, several members of Kennedy’s committee voiced discomfort with vaccinating all newborns. They argued that past safety studies of the vaccine in newborns was limited and it’s possible that larger, long-term studies could uncover a problem with the birth dose.

But two members said they saw no documented evidence of harm from the birth doses and suggested concern was based on speculation.

The panel was to vote Thursday, but voted to postpone after some members said they had just received the densely-worded vote proposals and wanted clarification and more time to consider it.

Three panel members asked about the scientific basis for saying that the first dose should be delayed for two months for many babies.

“This is unconscionable,” said committee member Dr. Joseph Hibbeln, who repeatedly voiced opposition to the proposal during the sometimes-heated two-day meeting.

The committee’s chair, Dr. Kirk Milhoan, said two months was chosen as a point where infants had matured beyond the neonatal stage. Hibbeln countered that there was no data presented that two months is an appropriate cut-off.

Some observers criticized the meeting, noting recent changes in how they are conducted. CDC scientists no longer present vaccine safety and effectiveness data to the committee. Instead, people who have been prominent voices in anti-vaccine circles were 

The committee “is no longer a legitimate scientific body,” said Elizabeth Jacobs, a member of Defend Public Health, an advocacy group of researchers and others that has opposed Trump administration health policies.

In a statement, she described the meeting this week as “an epidemiological crime scene” — a slaughter of how disease control professionals usually examine and act on evidence.
