A seismic shift landed in American delivery rooms today. Health Secretary Robert F. Kennedy Jr. has overseen a CDC advisory vote to stop universally recommending the hepatitis B vaccine at birth, reversing decades of practice that built a safety net for every newborn. Hospitals and state programs are now scrambling to interpret what this means for parents, pediatricians, and public health. This is a watershed moment for infant care, and it arrives alongside fresh scrutiny of Kennedy’s leadership amid a personal controversy that is fueling questions about trust and motive.
What changed, and why it matters right now
The reconstituted CDC Advisory Committee on Immunization Practices, selected during Kennedy’s tenure, voted to limit the birth dose of the hepatitis B vaccine to babies born to mothers who have hepatitis B or whose status is unknown. For years, the standard was simple, every baby got the first shot within 24 hours. That universal step caught silent cases and blocked the most dangerous route of spread, transmission at birth.
Hepatitis B is a virus that attacks the liver. The risk of lifelong infection is highest when infection happens at birth. Many infected infants look healthy at first, then face liver damage, cirrhosis, or cancer later in life. The birth dose was designed to be a safety net, because prenatal testing sometimes misses infections, and delivery room chaos can lead to errors.
The hepatitis B birth dose has served as a backstop when lab results are wrong, delayed, or missing. Removing that backstop raises the stakes.
The science and the stakes
The move lands amid other changes pushed by Kennedy. The CDC has softened public statements that vaccines do not cause autism, despite extensive research that finds no credible link. He also pulled 500 million dollars in federal mRNA vaccine funding earlier this year, shifting priorities away from that platform.
Here is the health risk with today’s decision. When the birth dose is not routine, more newborns depend on perfect paperwork and flawless timing. That is not how real life works. Prenatal care varies, lab results can be lost, and some births occur outside traditional settings. Gaps mean missed opportunities, and with hepatitis B, a miss at birth can last a lifetime.
Universal policies are blunt, but they are reliable. Targeted policies can be efficient, but they are fragile. If clinics, hospitals, or families falter, infections rise. That is the lesson public health has learned again and again with preventable diseases.
What parents should do now
Parents do not need panic, they need a plan. Your hospital may keep universal vaccination. Some states may also hold their current standards while they review the vote. Ask, verify, and document.
- Ask your obstetrician for your hepatitis B surface antigen result, and bring it to the hospital.
- If your status is unknown at delivery, request immediate newborn vaccination.
- If you are hepatitis B positive, your baby needs the vaccine and added protective medication within 12 hours, confirm this in writing.
- If vaccination is delayed, schedule the first dose with your pediatrician as soon as possible, ideally within the first month.
Put your prenatal lab results in your hospital bag, and snap a photo on your phone. Redundancy prevents mistakes.

Politics, trust, and your health
The policy shift collides with a new storm around Kennedy’s personal life. A memoir released last week alleges a romantic relationship during his 2024 campaign, and the fallout has already cost a high profile journalist her post. Personal drama is not medical data, but it does shape trust. In vaccines, trust is oxygen. People decide to vaccinate based on a clear message, a steady messenger, and a system that feels transparent. When leadership is under a cloud, confidence drops, and disease can find space to spread.
Public health thrives on simple messages that hold up on busy days. The hepatitis B birth dose was one of those messages. Diluting it, while reshaping who sits on the nation’s vaccine advisory panel, invites confusion in clinics and at kitchen tables.
Confusion leads to missed shots. Missed shots lead to preventable infections. Preventable infections lead to preventable deaths.
Frequently Asked Questions
Q: Should my newborn still get the hepatitis B shot at birth?
A: If your hepatitis B status is positive or unknown, yes, your baby should receive it right away. If you are documented negative, your hospital may follow the new guidance or keep universal vaccination. Ask your care team and plan ahead with your pediatrician.
Q: Is the hepatitis B vaccine safe for newborns?
A: The vaccine has been used in newborns for decades with strong safety monitoring. Large studies have not found a link between vaccines and autism.
Q: What if I had all my prenatal labs and I am negative?
A: Keep copies of your lab results with you. If your hospital delays the birth dose, ensure your baby starts the series at the first pediatric visit, usually within the first month.
Q: Could this change lead to more hepatitis B cases?
A: That is the concern. Without a universal safety net, any gaps in testing or documentation can result in missed protection at birth, which raises risk for lifelong infection.
Q: Do states have to follow this new guidance?
A: States and hospitals set their own protocols within broad guidance. Many will review their policies in the coming days, and some may keep universal birth dosing.
The bottom line
A single vote can echo through every nursery in the country. Today’s shift on hepatitis B at birth puts more weight on perfect prenatal testing and flawless coordination. Families can protect themselves by asking early, confirming results, and planning with their pediatrician. The science on protection is clear, and the stakes for infants are high. We will keep pressing for clarity, because on day one of life, there is no room for doubt.
