RFK Jr. Gets His Way as Advisers Change Hepatitis B Vaccine Guidance

A federal vaccine advisory panel handpicked by Health Secretary Robert F. Kennedy Jr. voted Friday to recommend delaying the hepatitis B vaccine for most newborns.

The 8–3 vote by the Advisory Committee on Immunization Practices reverses the government’s longtime stance that all babies be vaccinated at birth against the liver infection. Now the panel is recommending the vaccine—which has been credited with preventing thousands of illnesses—be given only to those infants whose mothers test positive or haven’t been tested.

If parents or guardians decide not to get the vaccination at the time of birth, the committee’s vote recommends that the baby should get the dose at two months. One committee member, Dr. Cody Meissner, expressed misgivings, saying, “We are doing harm by changing this wording, and I vote no.”

When asked Thursday by the Associated Press why the committee chose to reexamine this vaccine, committee member Vicky Pebsworth said it was because of “pressure from stakeholder groups wanting the policy to be revisited,” but did not elaborate. A spokesperson for Kennedy did not respond to a question on the subject. Senator Bill Cassidy, a doctor and liver specialist, called the committee “totally discredited” on Thursday.

In 2022, longtime vaccine skeptic Kennedy said the hepatitis B vaccine “was made for prostitutes and for promiscuous gay men.” The virus isn’t just spread through sexual contact, though: Even contact with small amounts of infected blood can put someone at risk.

Now the decision on whether to accept the recommendation goes to the acting head of the Centers for Disease Control and Prevention, Jim O’Neill. But the American Academy of Pediatrics plans to keep promoting the existing CDC guidance for babies to get the first dose of the vaccine at birth, followed by a second at one or two months with the third dose coming between six and 18 months.

At least one state will also continue recommending the hepatitis B vaccine at birth: Governor Maura Healey of Massachusetts said on CNN Thursday that “D.C., the Trump administration, RFK, that panel, they are not doing their jobs. And in the face of that, as governor, I’m going to do mine.”

Since newborns began getting the Hepatitis B vaccine in 1991, we’ve seen a 99% reduction in pediatric infections.

Now, RFK Jr. and his conspiracy theorists want to take away all that progress.
