DHS Reiterates Recommendations That Newborns Get Vaccinated For Hepatitis B

Wisconsin’s health department is reaffirming longstanding recommendations that all newborns get a vaccination for hepatitis B.

The Department of Health Services announced Thursday it has sent a memo to Wisconsin vaccination providers about the vaccine.

“DHS continues to recommend that all newborns receive the hepatitis B vaccine within 24 hours of birth, and then go on to complete the standard three-dose series within the first 18 months of life,” said Dr. Ryan Westergaard, chief medical officer in the DHS bureau of communicable diseases, at a media briefing Thursday.

Hepatitis B, a viral infection, can lead to lifelong liver disease, Westergaard said, including cirrhosis and liver cancer.

“Infants and young children are particularly at high risk,” he said. A baby infected with the virus has up to a 90% chance of developing chronic liver disease, he said.

Infants can be exposed during birth or through close contact with adults and caregivers “who may not even know that they carry the virus,” Westergaard added. “That’s why vaccination early in life is so important.”

DHS issued the announcement following a federal shift in vaccine policy, eliminating a recommendation in place since 1991 for newborns to receive the hepatitis B shot. The recommendation was eliminated Dec. 5 in a vote by the Advisory Committee on Immunization Practices at the Centers for Disease Control and Prevention.

In June, U.S. Health and Human Services Secretary Robert F. Kennedy Jr. replaced all 17 members of the advisory committee with a new group of appointees, many of whom are seen as vaccine skeptics.

The decision to end the recommendation for all newborns to get the hepatitis B shot dismayed the leaders of medical organizations, including the American Medical Association and the Association of State and Territorial Health Officials.

“For more than 30 years, the hepatitis B vaccine has been used safely and effectively in newborns,” Westergaard said Thursday. Since the 1991 recommendation was put in place, hepatitis B infections in children have declined by 99%, he said.

“This recommendation is grounded in decades of research showing that the vaccine is safe and effective, and it aligns with guidance of the American Academy of Pediatrics and other leading medical groups,” Westergaard said. “So, our message today is straightforward: hepatitis B and its long-term health consequences are preventable. And routine childhood vaccination remains one of our most effective tools we have to protect children’s health and prevent lifelong disease.”

Westergaard said there has been no change in insurance coverage for the vaccine and that the hepatitis B shot remains among the vaccines available through the Vaccine for Children’s program for patients without health insurance.

ACIP also recommended blood testing for antibodies before giving the rest of the hepatitis B series shots for infants and young children, but Westergaard said that recommendation is not supported by scientific evidence.

The presence of hepatitis B antibodies in adults is a good indicator that they are protected against an infection, he said. “There’s no science suggesting that that same strategy works for newborns and children,” he added.
